Close Mold Flow Mat FR (Fire Resistant) is a newly developed sandwich material made from glass fibers that meets the strict hazard level (HL) classifications under the EN 45545 standard, which sets the European benchmark for fire protection in railway vehicles.

This material has successfully undergone the FIRST tests, which assess Flame spread, Ignitability, Rate of heat release, Smoke opacity and Toxicity of smoke. It has also met the most stringent certification requirements for underground vehicles such as metro, rapid-transit trains, and sleeper trains.

The EN 45545 standard was established in Europe in 2013 and is set to become effective in 2016. Its goal is to reduce the likelihood of incipient fires and contain the spread of fire to minimize the impact on passengers and onboard personnel.

RTM Flow Mat (Fire Resistant) is an excellent addition to the Flow Mat series, specifically designed for producing composite parts that are fire-resistant. Its unique porous core construction is halogen-free, which minimizes smoke toxicity in case of a fire.

This product is ideally suited for closed mold processes such as RTM, Light-RTM, and infusion. Its core design makes it particularly effective for low-pressure injection processes.

Despite the changes to the core, RTM FLOW MAT retains all the advantages of the Flow Mat range, including excellent conformability, elongation, and resilience. It adapts well to varying thicknesses of composite parts and ensures uniform wet-out throughout the reinforcement.

Using RTM FLOW MAT saves time and reduces costs. Its main benefit lies in its fire-resistant properties, making it an ideal option for obtaining an HL3 rating according to the new NF EN 45 545 standards.
