Technical Datasheet | Supplied by GreenChemicals SPA
GC RE DDP by GreenChemicals acts as a halogen-free reactive flame retardant. It is a 2-(6-Oxido-6H-dibenz,c-e, 1,2 oxaphosphorin-6-y) methyl butandioic acid. It is free of heavy metals and derived from organophosphorus substances. It exhibits high purity and indispensable property in chemical synthesis. It can be diluted in dimethylformamide (DMF), dimethyl sulfoxide (DMSO), organic solvents and ketones. It offers excellent thermal stability, resistance to hydrolysis & hygroscopicity and color stability in polymerization. GC RE DDP shows compatibility with polyesters, polyamides and TPUs.
