About this product
Glass-Fiber Reinforced PP Compounds (10–40%) — product overview
Auto-GRPP is Allzone's chemically-coupled glass-fibre reinforced polypropylene programme, offered in loading levels between 10% and 40% glass. GF-PP is the workhorse structural polymer for under-the-hood brackets, bumpers, front-end modules and appliance frames because it delivers a high stiffness-to-weight ratio at moulding cost significantly lower than engineering resins. Actual tensile strength, HDT and shrinkage are strongly driven by glass loading, fibre length retention through the moulding process, and gate design — a small design change on the part can shift mechanical performance more than a switch of GF loading. Loading level, coupling chemistry and colour options are confirmed at RFQ; validation on the customer's own tool is recommended.
