Modified glass fiber reinforced polypropylene material is a kind of PP modified material with glass fiber as a reinforcing agent. The reasonable length of the glass fiber is controlled through a unique process and a combination of twin screws. The auxiliaries are optimized to make the glass fiber and resin have better performance. The compatibility and dispersibility of the material, thereby greatly improving the material rigidity, impact strength, tensile strength, heat resistance, and dimensional shrinkage. The materials can meet ROHS environmental protection requirements and are mainly used in parts such as washing machine drums, car fans, bottom guards, instrument skeletons, and housings of household appliances. TOPO engineering plastics can provide customized services according to the specific requirements of customers and is your trusted manufacturer of modified plastics.
