Reinforced polypropylene (PP) is a high-performance composite material made by incorporating glass fiber reinforcement components into polypropylene resin. The addition of glass fibers improves the material's heat resistance, limitingthe movement between the plastic-polymer chains. Therefore, the shrinkage of glass fiber reinforced polypropylene isreduced, and the rigidity, impact resistance, tensile strength, compressive strength, flexural strength and flame retardancy are all improved.It has better strength and toughness, and its comprehensive performance reaches and exceeds that of general-purpose plastics. Good mechanical strength and high modulus, can work under considerable load. It has good heatresistance, excellent impact toughness, and good chemical stability, and can maintain its performance under theinfluence of many chemical media. It is used in electronic components, distribution boxes, capacitor terminal boards,household appliances and chemical equipment.
