Charmor™ micronized polyols are a rich carbon source for production of superior intumescent systems. Charmor™ PT40 is a micronized Pentaerythritol derivative. Charmor™ micronized polyols are a critical component in the formation of a thick fire resistant char barrier when intumescent coatings are exposed to high temperatures. In intumescent systems for plastics, Charmor™ PT40 is used as carbon source for halogen free systems demanding lower smoke release and non-toxic fumes.
