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.

Polym. Adv. Technol. 2016, 27 303–307

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

advanced materials

49

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
