Combustion modified high resilience foam

Combustion modified high resilience foam

CH foams are fire retardant, high-resilience polyurethane foams. They offer quality support in cushioning with a range of different comfort feels whilst providing all characteristics of a flame retardant foam.

CMHR (Combustion Modified High Resilience) foams are primarily used in the furniture industry in order to conform to fire safety standards. CMHR foam grades typically range in density from 25 to 45 kg/m3.
