摘要

Injection molded automotive component made from polyester composites, comprising of at least a polyester, glass filler, epoxy additive, antistatic agents, thermal stabilizers, process stabilizers and antioxidant additives; wherein polyester composite comprises combination at least two different IV of polyesters, preferably recycled poly ethylene terephthalate (RPET) resin 55-92% by weight and the RPET resin having the IV range from 0.1 - 1.5; wherein these two IVs are from two different consumer used sources, one IV is from PET bottles and another IV is from non bottle source like PET films and fibers; wherein most optimized range of glass filler (silica fibers) is 22 - 36 % by weight; wherein epoxy additive of low molecular weight (100 to 3000 gram/mole) is 0.05 to 3% by weight; wherein antistatic agents are from metal alkyl sulphonate derivatives and is 0.02 to 5% by weight; wherein process stabilizer is 0.05 to 1% by weight of stearate based additive.
