Description
PP is the base resin and it is uniformly mixed with fire retardant, glass fiber, POE and processing modifier in a high speed. After twin-screw kneading granulation, reinforced polypropylene compound (PP+POE granules) is formed. Its flame retardant grade is UL94 V-0. This halogen free flame retardant compound owns excellent mechanical strength, excellent resistance to stress cracking, heat resistance and good workability. This reinforced polypropylene compound is used for electroplating processing and also applied in home appliances, electronic appliances and other fields.
