Clariant Flame Retardant Exolit AP 766 (TP) is a halogen-free flame retardant based on phosphorus-nitrogen synergy. It adopts an intumescent flame-retardant mechanism—when thermoplastic foams or crosslinkers contact flame, it forms a stable surface barrier. This barrier provides thermal insulation, reduces oxygen access, and prevents molten polymer dripping.
