Pyrell ®

An Intumescent Fire-Retardant Foam
By Foamex

General Description

Pyrell ® Foam is a combustion modified, flexible polyester polyurethane foam. When flame is applied, Pyrell ® intumesces. The surface chars, tending to form a protective shield between the flame and the foam underneath. This carbon char has low thermal conductivity and high oxidation resistance.

Unlike conventional urethane foams, Pyrell ® Foam will not melt and drip. It virtually eliminates the danger of hot or flaming droplets, and helps protect against the possibility of secondary fires.
