The HFFR compound that redefines the limit.

High-performance Halogen-Free Flame Retardant formulations for cables, construction and critical infrastructure. Engineered in Italy by the STIR laboratory.

HFFR Technology

Zero halogens. Zero compromises.

Evolut HFFR is the Halogen-Free Flame Retardant compound line developed by STIR Compounds for high-criticality applications. Total absence of halogens, reduced emissions in case of fire, maintenance of mechanical properties even at high temperature.

Every formulation is born in the STIR laboratory and is optimised based on the customer's extrusion process, guaranteeing compatibility with existing lines and batch-to-batch reproducibility.
