Reinforced PP has glass fiber reinforcement and mineral filling reinforcement.

PP glass fiber reinforced, because the glass fiber is added to the PP material, the mutual movement of the polymer chains in the plastic is restricted, and the shrinkage rate is reduced. After glass fiber reinforcement, the rigidity, tensile strength, compressive strength, bending strength and flame retardancy of the PP material are improved, and the heat-resistant temperature of the material is also improved. Mainly used in smart toilet accessories, water tank accessories, and sports equipment.

Mineral-filled PP usually adds non-metallic mineral powder materials to the plastic, such as calcium carbonate, dao lime, talc powder, mica powder, kaolin, wollastonite powder, aluminum hydroxide, magnesium hydroxide or brucite powder, Precipitating barium sulfate or barite powder, etc. Increase the thermal deformation temperature of PP plastics, increase product dimensional stability, reduce molding shrinkage, increase rigidity, and reduce costs. Mineral-filled PP modified plastics are mainly used in small household appliances shells, outdoor units of air conditioners, various electronic and electrical components, engineering structural components, etc.
