Intumescent Resins with Graphene

Advanced Fire Protection

At Graphenano Composites, we develop next-generation graphene-based intumescent resins, designed to provide maximum fire protection without compromising the mechanical properties of the material.

Our Poligraph, Vinilgraph, and Epoxigraph product lines can be formulated with halogen-free flame retardants, such as ammonium polyphosphate, achieving ultra-resistant composite materials that meet the highest safety standards.

 

What is intumescent protection?

Intumescent technology actively responds to fire:

  • At high temperatures, the additive acts as an acid donor
  • An expanded carbonaceous foam is generated
  • This layer acts as a protective thermal barrier

The result is effective protection of the composite’s structural core, reducing fire spread and limiting temperature rise.

Available Versions

We offer fire-retardant versions across the following resin families, all adaptable to the specific requirements of each project:

Epoxy Resins (Epoxigraph)

These formulations are already used in advanced systems such as Epoxigraph Ceramic, a graphene-reinforced epoxy system designed to enhance structural strength in ceramic materials, marble, and stone—while also providing flame retardancy, thermal stability, and durability in aggressive environments.

Polyester Resins (Poligraph)

Thanks to their ease of processing and compatibility with reinforcements, fire-retardant Poligraph resins are an excellent choice for sectors such as construction, infrastructure, and automotive, where the balance between performance, safety, and efficiency is essential.

Vinyl Ester Resins (Vinilgraph)

Fire-retardant Vinilgraph vinyl ester resins combine fire protection with outstanding chemical and corrosion resistance, making them the ideal solution for highly aggressive environments.
