Introduction
BDDP is a kind of high performance flame retardant containing both aromatic bromide and aliphatic bromide，good thermal stability and light stability. Because ，can be melted into a homogeneous dispersion and mixed with the plastic in the general plastic processing temperature, and no layered, no blooming. Especially applicate in PP，only need 8—10% with 2—3% Sb2O3 can make PP meet the UL94-V0 requirement，is one of the best flame retardants used in PP.
