Glass Fiber reinforced Polypropylene(PP) PALL RING
Glass fiber reinforced PP is the modified plastics with good mechanical properties, heat resistance good resistance to chemical, good flow and processibility.
Glass fiber reinforced PP is used for structure and function parts, such as washing machine parts, automobile fan, skeleton of instrument panel, household water meter, centrifuge and axial fan blades of industry, housewares, irrigation equipment parts, textile equipment parts, sewage disposal equipment parts, etc.
