HF-T914 DOPO-DDP Reactive Flame Retardant Halogen-Free Phosphorus-Based For PET

Product Specification

HF-T914 DOPO-DDP Reactive Flame Retardant | Halogen-Free Phosphorus-Based | For PET Fibers/PU Foams | Wash-Resistant | RoHS/REACH Compliant

Product Overview

HF-T914 is [(6-Oxido-6H-dibenz[c,e][1,2]oxaphosphorin-6-yl)methyl]butanedioic acid (DOPO-DDP, CAS: 63562-33-4), a reactive phosphorus-based flame retardant with dual gas-phase radical quenching and char-forming mechanisms. Designed for fiber and foam applications, it offers permanent flame retardancy without migration.
