Reofos TPP Flame Retardant Plasticizer from China

Reofos TPP is a commercial-grade triphenyl phosphate serving as a high-boiling plasticizer and flame retardant for engineering plastics like polycarbonate blends. Classified under HTS 2919.90.1500 due to its aromatic structure and explicit plasticizer function as a phosphoric ester, aligning with chapter requirements for separate chemically defined compounds. It imparts flexibility and fire resistance without altering the base polymer significantly.
