Schockproof polyester-injected parts

摘要

Polyester injection-moulded parts based on a polyester (A) and on a copolymer (B) of ethylene and of an unsaturated epoxy, such that weight % (B)xMFI (A+B)/MFI(A) is greater than 3 and in this expression:MFI (A+B) denotes the melt flow index of the modified polyester, that is to say the blend of (A) and (B) and of any fillers;MFI (A) denotes the melt flow index of the polyester (A) and of any fillers (without (B)); andweight % (B) denotes the percentage by weight of (B) in the blend of (A) and (B) and of any fillers.
