Avanzare not only commercializes graphene and its derivatives, but since the
beginning we have been closely linked to the nanomaterials sector. Avanzare offers
different solutions: by one hand, solutions only based on nanomaterials; and on the
other, products in which we are looking for synergistic effects between different
types of materials.

What allows us to offer nanotechnology when designing a chemical
tademark additive?
• They allow differentiating your material/blend so that illegitimate claims will
be avoided.
• Disincentive and entry barrier for unsafe raw materials suppliers.
• They enable to reduce costs on civil liability insurance.
• Tailor made in terms of design and security levels preferences.
• Very low required dosage and cost repercussion.

The results showed that graphene acts as a nucleant agent at very small (0.3
wt%) amount leading to a foam with a smaller average cell diameter with
respect to un-filled foam
At that level (0,3 wt%) the thermal conductivity is lower (18%)

Flame Retardant
• Each type of material presents different fire behavior, so there must
be different solutions.
• Depending on the type of material (GOx, graphene, GNPs ... other
FR materials) there will be a different fire behavior:
- Active / reactive against fire
- Catalytic Properties
- Barrier or Chart Effect
- Anti-drip

Physical:• Cooling effect (releasing water, etc.)
• Formation of protective layer
• Dilution
• Decrease in dripping effect
Chemistry:• Free radical scavenger
• Catalytic degradation of the polymer and / or chart creation
• Reduce the concentration of flammable gases in the polymer and / or O2
• Creation of intumescent layers, alone, or combined with other FR

How does graphene work?
• Barrier formation
• Migrating graphene .... Small size
• Other effects:
o Prevent the movement of macromolecules by crosslinking
the polymer chains
o Catalytic formation of intumescent layers type chart
o Active RF encapsulation / intercalation: ammonium salts ....
o Capture of radicals .... Usually by metals in the layer of
graphene .... "Graphene decorated"
o Smoke Reduction
o Anti-drippingavanzare
