Graphenano Composites is a pioneer in the development of composites with graphene additive. For the construction sector, Graphenano manufacture a wide range of resins doped with graphene for profiles .

Graphenano Composites works with commercial thermo stable resins (polyester, vinylester and epoxy), these doped with graphene.
Glass fibre is a good heat insulator, inert to acids and capable of withstanding high temperatures. Resins doped with graphene provide more advantages to the final composites such as greater strength, greater rigidity and anti-corrosion, fireproof and self-extinguishing properties.
In the pultrusion process, the glass fibres impregnated with resins are subjected to pulling operations and enclosed in a closed mould at high temperature so that the polymerising and curing process of the resin occurs in their interior.
Its advantages compared to other processes notably include:
- High rigidity and consistency of the end products.
- Versatility of shapes, depending on the geometry of the mould.
- Profiles cut to measure. Possibility of obtaining long lengths.
- High production speed and continuity.
- Good surface finish.
