Cables used in buildings, automotive public transportation and power networks are required to have strong fire resistance and low smoke generation. Halogen Free Flame Retardant (HFFR*) compounds are made of polyethylene, Lotryl®/Evatane® copolymers, high mineral fillers loading (ATH or MDH) and Orevac®/Lotader® coupling agents. Coupling agents facilitate compounding with high filler content, as well as improve flame retardancy and mechanical properties (before and after ageing).

* Also called:​ Low smoke non halogen (LSNH)​ / Low smoke 0-halogen (LS0H, LSZH)​ / Eco-product (In Japan)
