What is Vytex® Natural Rubber Latex?

A fully commercialized source material, using a multi-patented

process and green chemistry to significantly reduce non-rubber

components, including antigenic proteins, for a more

consistent, stable and cleaner natural rubber latex

Vytex® NRL Technology

Vystar® Corporation Covers the Market

Vytex Production

New Standard of Latex

Vytex® NRL Meets the New ASTM D1076-10 Category 5 Standard

“Centrifuged Hevea natural latex treated with aluminum hydroxide or by

other means, preserved with ammonia……containing less than

0.5 % non-rubber content.”

Clean Room and Specialty Gloves

Clean room gloves made with Vytex® require

~ 50% less leaching to remove non-rubbers

and chemical particles • Lower product rejection rates due to extensive alkaline washes

• Decreased energy, water and waste usage

Vytex® use with common antimicrobials is superior to NRL- will not

react and de-stabilize

Protein Results in Clean Room Gloves Using Comparative Leaching Processes

Testing conducted by Malaysian Glove Manufacturer

Vytex® NRL Advancements: Condoms

Naturally whiter, more translucent

condoms

Condoms made with Vytex® NRL

contained 35% fewer nitrosamines than traditional latex*

Significantly reduced odor compared to NRL

US FDA protein claim “less than 2 µg/dm2 antigenic protein”

* Customer Test Data

Whiter, cleaner balloons for brighter,

truer colors with less pigment usage

Reduced usage of pigments and

whiteners (TiO2)

Better air and helium retention in balloons

Vytex® NRL Advancements: Adhesives

Spray Adhesives

Less non-rubber debris for cleaner spray

Absence of non-rubber debris reduces spray-head clogging;

decreased equipment/line downtime

Cleaner adhesives flow easily; allowing for gravity-fed system

vs. pump system using propellants

~ 40% faster tack time in some formulations compared to

traditional latex

How Vytex® NRL is Helping to Solve Customer Product

Development Challenges:

Adhesives for Personal Care Products

Safe and effective skin adhesive which can be easily and

safely removed

Result:

Material with excellent adhesive quality

Low levels of protein

Adhesive can easily be removed with soap

Vytex® NRL Advancements: Foam Products

Virtually Odor Free

Significantly reduced leaching

No fragrances required to mask or eliminate odor

Vytex® process eliminates microbial food sources that

break down to cause odor and accelerated aging

Whiter, Cleaner Foams

Customized Foams

Goal: a greener, naturally based foam with slow recovery properties

Vytex® NRL Threads: Lower Modulus/Higher Elongation Easier Donning and Greater Comfort

Testing conducted by North Carolina State University, College of Textiles

Specialty Fabrics for Personal Protection Products

Goal: • Latex based apparel that can worn daily

• Fabric must retain fluids to prevent leakage

• Fabric must be easy to don and comfortable to wear

• Production process does not include a leaching step

Result: • Low levels of antigenic proteins

• Tight film structure minimizes leakage

• Low modulus material for easy donning

Opportunities for Further Enhancements to Vytex® NRL

No Ammonia Alternative

Ammonia Preserved CL 60 is the Industry Standard

• Current low ammonia levels to 0.20 – 0.35%

• However, TMTD used as a preservative and therefore CL60 is not

Nitrosamine-free

Growing demand for improved lattices:

• Low VOCs for use in enclosed factory spaces

• Specialty end use applications such as body paints, adhesives, etc.

• Without ammonia or TMTD used at any stage of preservation

Very Low Ammonia Vytex NRLO5 (<.05% ammonia) currently available

Conclusions

Vytex® NRL Multi-patented Process

Physically removes non-rubbers, including proteins,

from liquid natural latex

Meets new Category 5 standards of ASTM D1076-10

Conclusions

Products Made with Vytex® NRL

Exam gloves and condoms: FDA 510(k) allowances of protein claims

Foams: naturally whiter with minimal latex odor

Balloons: truer colors and better air/helium retention

Dipped goods: less leaching/improved environmental impact

Vystar R&D focuses on addressing our customers’ varied

product and production challenges
