Silicone Elastomers for rubber industries

> Why choosing Silicone Elastomers?

n Stable, high performance polymersSilicones outperform most other polymers: Silicones have remarkable spreading capability coupled with outstanding resistance to extreme temperatures, UV and IR radiation as well as to attack from a multitude of other external agents. Without question, means that silicones rank among the very highest performance polymers.

n A wide range of applicationsSilicone elastomers, outstanding properties are used for many different industrial applications: piping in fluid circuitry and sealing (joints for building construction and aeronautical application, automotive gasket, boots and hoses), electrical protection (office equipment, safety cables and insulators for electrotechnical applications, spark plug boots, cables and connectors for automotive application). Food, pharmaceutical and biomedical applications (tubes, profiled sections) are made using heat cure elastomers from the Silbione range, which are specially formulated to comply with European and American regulations.

n Macromolecules with unlimited structural possibilitiesSilicones (or polyorgano-siloxanes) have a chemical structure based on alternating units of silicon and oxygen. The originality of silicones compared with natural silica, lies in the organic, carbon-containing groups that are included in their molecular framework.According to the type of organic groups attached in this way, and the production and compounding methods used, a great variety of products can be obtained: their final texture can be free flowing, viscous or paste-like, elastomeric or even rigid.

n A mineral - plastic hybridThe difference between silicones and other organic polymers (i.e. plastics) lies in the fact that they contain a semi-inorganic element, silicon bonded to oxygen atoms with Si-O- bonds.The bonds formed between the silicon and oxygen atoms go to make up the macromolecular framework and are exceptionally stable. They are much more difficult to break than the carbon-carbon bonds found in organic polymers.

Main outstanding properties of silicone elastomers

u Heat stability in continuous use from - 50 to 200 °C (can be increased up to 300 °C using specific additives).

u Exceptional ageing resistance (even under extreme conditions).

u Great versatility of use.

u High innocuity due to the inorganic Si-O-Si chain.

u A wide range of Color Master Batches available and possibility to produce transparent products.

> A complete range of silicone elastomers for the rubber industry including numerous different technologies. Rhodorsil® HCRHeat cure silicone elastomers are basically made from reactive silicone gums and specific silica fillers.Rhodorsil® HCR have outstanding properties and are far superior to conventional organic elastomers. They exhibit exceptional mechanical strength at temperatures ranging from - 50 °C up to + 300 °C. The ageing resistance of these elastomers highlights fundamental qualities such as the fact they are chemically inert, photo-oxidative stable and are absent of residual reactive groups once cured. A wide range of colors is available.HCRs are available as rubbery breads and supplied in two forms: master batches (without incorporated catalyst) or as ready to use compounds (through Bluestar Silicones’ Mix & Fix Centers®).

Rhodorsil® FIMRhodorsil® FIM Polyaddition HCR (Fast Cure Injection Molding) is a range of platinum catalyzed HCR silicones. The polyaddition crosslinking reaction is much quicker than that initiated by peroxides and does not generate any toxic by-products. This is why Rhodorsil® FIM allows improved productivity and represents an excellent combination between mechanical properties, respect for the environment and improved working conditions.Rhodorsil® FIM is easily processed using mold and injection presses already used in the rubber industry, without further investment.

Silbione® HCR and LSRSilbione® LSR are two-component systems in which viscosities are generally between 10 000 and approximately 106 mPas. This type of formulation forms an elastomeric network thanks to reactions of polyaddition in the presence of a platinum catalyst.The processing and product performance advantages of liquid silicon rubber (LSR) are utilized in many existing and new applications. This type of rubber can associate essential properties of silicone polymers and easy injection molding processing.After mixing A and B parts in a static or dynamic mixer, the largest means of transformation are: injection-molding machines working at medium or high pressures, or pumps directly feeding a mold at ambient pressure. These mixtures are vulcanizable from 60 °C to around 150 °C.Silbione® are a range of silicone elastomers dedicated to food contact, pharmaceutical and biomedical applications. Silbiones are HTR or LSR whose raw materials are in accordance with regulations (ie: positive lists). They are manufactured, then controlled according to a specific process protocol. With the Silbione range you are certain to implement only elastomers in conformity with the regulations in place.

Additives & Colors> Additives: they can be used in all HCR master batches and are distributed in two categories: Processing enhancing additives and Performance enhancing additives.> Color Master batches: many different colors.

Heat resistanceIn order to produce products answering strict criteria in terms of heat resistance, Bluestar Silicones developed a very high temperature resistance range, which can resist until 300 °C without significant deterioration of its properties.Bluestar Silicones also offers a complete range of additives allowing the improvement of the heat stability of all master batches.

> THT series

Oil resistanceGenerally, the aggressiveness of the engine oils with elastomers increases with temperature, and espacially with temperatures higher than 100-120 °C. Beyond 150 °C, only silicones can ensure a sufficient sealing for automobile gasketing.

In order to produce products answering strict criteria in terms of oil resistance, Bluestar Silicones proposes one series of products:

> 600 series

Coolant resistanceThe severe conditions under the hood are requiring new generation of coolant fluids which are rather agressive versus elastomers pipes. 700 series are designed to produce hoses and parts with extended life.

Rhodorsil® FIM polyaddition HCR for increased productivity

n Significant increase in productivity> Cure kinetics 2 to 3 times quicker than those measured on peroxide grades.

n Outstanding processability> Excellent demolding (no surface tack).> Significant reduction in reject rate: very good tear strength at high temperature, curing relatively insensitive to temperature uniformity (complex molds, multi-cavity molds, thick-section part, etc.).

n Very good mechanical properties> Excellent compromise between elongation at break / tear strength / compression set.

n Low temperature curability> Energy savings, insert molding of sensitive parts.

n Respect for the environment and improved conditions at work> Free of peroxide residues.> Odorless vulcanizing.

> Advantages of Rhodorsil® FIM polyaddition HCR

Optimized productivity is often achieved by complex mold design

(increasing number of cavities). This in turn makes temperatures and

material critical parameters more difficult to control. Part quality can

consequently suffer with anormally high reject rates.

Constantly at the forefront of innovation, Bluestar Silicones is offering

a range of platinum catalysed silicones (polyaddition reaction):

> Rhodorsil® FIM polyaddition HCR (Fast cure Injection Molding).

> Rhodorsil® FIM polyaddition HCR can be easily processed using mold

and injection presses already used in the rubber industry, without further

investment.

“Mix & Fix Centers®” have the job of preparing samples for approval and delivering special ready-mixed products, in the best timing.

“Mix & Fix Centers®” represent an invaluable potential resource for rubber converters, engineering offices, R&D establishments and materials testing facilities.

Scorch time (TS2)The scorch time for Rhodorsil® FIM polyaddition HCR blends can be increased or decreased without significantly changing the cure rate or cross link density.

> Rhodorsil® FIM polyaddition HCR offers the possibility of optimizing molding characteristics to your requirements.

When using peroxide blends, it is common to vary the peroxide content to improve the scorch time. The small gain in scorch time obtained is always accompanied by a significant change in cure rate and cross link density.

Reduction in reject ratesIt is also possible to increase the scorch time (TS2) by reducing the mold temperature without significantly affecting productivity. For peroxide blends, a lower molding temperature causes a dramatic increase in cure time.

Impact of temperature variations

> The FIM system is much less sensitive than peroxide systems to temperature variations.

Depending on the geometry of the molded part and elastomer used, the temperature can vary by between 10 and 20 °C from the center to the mold surface. With peroxide blends, these temperature differences can cause wide variations in cure kinetics and in the elastomer’s physical properties: in a multi-cavity mold, certain parts can be correctly cured while others are still under cured.

The platinum system in Rhodorsil® FIM polyaddition HCR means that the cross link density changes very little: the end properties of the elastomer are uniform and all the parts in a complex mold are cured at the same time.

Vulcanization technology: compared curing levels

The graphs opposite illustrate the differences between the two reactions.The graph for platinum, due to a very high cure rate, reaches maximum torque very quickly. The much quicker kinetic of Rhodorsil® FIM polyaddition HCR causes a significant reduction in finished article production costs.The injection-molding cycle time can be cut by two or even three times compared with peroxide versions, according to the dimensions and complexity of the part to be molded.The much slower cure rate of peroxide elastomers means multi-cavity molds must be used to achieve reasonable production yields. It becomes more difficult to achieve optimum quality levels and reject rate increase.The much faster cure rate of Rhodorsil® FIM polyaddition HCR enable less complex molds to be used (cheaper to produce). Better temperature control and better control of material flow properties make it possible to produce finished parts to much tighter specifications.

Polyaddition crosslinking reactionThe polyaddition crosslinking reaction (first order reaction) is much quicker than that initiated by peroxides and does not generate any toxic by-products.> No reaction by-product.> Respect for the environment.> Odorless.> Improved conditions for employees.

Tubing for fluid handling

n For end usersThese products have all the advantages: > High innocuity due to the inorganic Si-O-Si chain.> High level of transparency.> Suitable composition: absence of compounds affecting taste.> Absence of nitrosamines either in the elastomer or in the initial compound.> Excellent mechanical characteristics.> Outstanding physico-chemical stability:- wide range of use (-50 °C + 200 °C) with excellent resistance to thermal ageing and oxidising agents (oxygen, ozone, UV)- excellent behaviour when sterilised.


Silbione® HCR

> A perfect match between characteristics / applications

High level of transparencySilbione® HCR’s high level of transparency is achieved through the use of products with a very high level of purity enabling excellent observation of conveyed liquids.

Absence of nitrosaminesThe high transparency, combined with the absence of nitrosamines in Silbione® HCR master batches, makes them ideally suited to producing articles for infant applications (baby bottle teats, soothers, toys). Tests have been performed to demonstrate the absence of nitrosamines. The reports are available upon request.

Very low level of post-curingDue to the low volatile content in Silbione® HCR master batches, these products conform to regulation after short post-curing cycles such as 4 hrs at 200 °C. The recommended minimum amount of air is 100 l/min per kg rubber.

Excellent mechanical characteristicsThe mechanical characteristics of Silbione® 71000 series HCR’s are particularly well suited to these application types: > tear strength, tensile strength especially for infant applications> high resilience for drain and catheter applications, and peristaltic pump accessories.

Safe and biocompatibleThe carefully selected components that make up Silbione® HCR’s enable safe articles to be manufactured according to the criteria set down in the Pharmacopoeia. When processed under optimum conditions, the articles meet the biocompatibility criteria generally applicable to products based on silicone elastomers such as:> the absence of hemolysis> the absence of tissue and bacterial adhesion.Silicones have these qualities due to their ability to produce non-polar surfaces which therefore have very little interaction with biological systems and pose no health risks.

Conformity with regulationThe elastomer obtained by curing and post-curing Silbione® HCR master batch for 4 hrs at 200 °C only contains substances authorised by the following regulations:> France: Journal Officiel dated Nov. 25, 1992 - Brochure 1227.> Italy: Gazetta Officiale decreto 1973 and addendum.> Germany: BfR Part XV Silicones.> USA: FDA Code of Federal Regulation 21 - Chap. 177.2600.

A Silbione® LSR range is also available.Refer to the data file Silbione® LSR.

The Silbione® LSR range is well adapted to pharmaceutical and

health care applications due to the good biocompatibility of silicone

and their ability to produce non polar surfaces which therefore have

very little interaction with biological systems. Due to their high level

of mechanical properties and clarity, Silbione® LSR are particularly

suited for highly transparent molded parts such as baby nipples,

pacifiers, stoppers and valves. These grades show an excellent

resistance to standard sterilization technologies.

Rhodorsil® Additives & Color Master Batches






Color master batches for Rhodorsil® HCR provide a guarantee of quality and performance for all silicone heat cure elastomers which require pigmentation for technical or aestetical reasons.

> High pigmentation with economical levels.> Optimum consistency, which allows fast addition on a 2-roll mill.> To obtain good mixing it is advised to add the Color Master Batch(es) after the curing agent and any other additive(s).

Bluestar Silicones ref. RAL equiv.

Recommended levels and colorsThe recommanded levels are 1,2% for most color master batches but for grey and black colors 0,4 to 0,5 % are sufficient. The above recommanded levels give the shade of colour in ASTM slabs using Rhodorsil® MF 175 USP catalysed with 2,5 -dimethyl -2,5 di(tertiobutylperoxy) hexane, cured 10 min. at 170 °C and post-cured 4 hours at 200 °C.

Quality and consistency of the colorsThe colors are tuned by trichomatic spectrometry to minimize the variation of shade from one batch to another.

High temperature performanceMaster batches for silicone heat cure elastomers from Bluestar Silicones have particularly good resistance to thermal aging (and in the case of the “THT” range, extremely good resistance) they have been selected for their outstanding resistance to high temperature over extended periods.
