Valmont Utility has chosen TFP’s non-halogenated fire protection nonwovens, enabling new composite structure poles to resist 1150°C without structural loss. Valmont is a global leader in engineered products for infrastructure, communication and energy transmission structures and industrial construction. pinfa-na member TFP (Technical Fibre Products Ltd)’s PIN FR nonwoven mat is integrated into Valmont’s new composite poles, by centrifugal casting and filament winding, and protects the structure from fire by intumescent char. Utility poles must ensure integrity of transmission infra-structure in wildfires. The new composite poles pass the USA Utility Company Consortium Fire Test, UL94-V0, ASTM E84 (Steiner Tun-nel, Class 1) and pre- and post-burn ASTM D1036 Pole Bending Test.
