Description

This halogen free flame retardant has a wide range of expansion temperature and can be used for foams, paints, resins, rubber and more. Expandable Graphite is a stratiform graphite and contains acids between each stratums. Once it’s heated, acid generates gas and stratiforms are expanded. This expanded stable structure puts off a fire by cutting off the supply of air. (LOI is 28 by adding 15% in Polypropylene)
