Talc filled polypropylene for central air conditioning air intake grilles

As we all know, PP has the advantages of low density, chemical resistance, low cost, high temperature resistance, etc. However, PP material has a large shrinkage rate, low rigidity and hardness, and is prone to deformation when producing large parts. PP+ filling can effectively solve this problem. 

Talcum powder is widely used for filling modification of PP. When a small amount of talc is added to polypropylene PP, it can act as a nucleating agent, refine the grains, and improve the crystallinity of polypropylene, thereby improving the mechanical properties of polypropylene and improving its transparency.

Talcum powder-filled polypropylene is divided into two categories. One type has a filling amount of 30% to 40%. After modification of the polypropylene, the heat deformation temperature and flexural modulus can be increased; the other type has a filling amount of 10% to 20%. , can improve the surface finish of polypropylene.

Filling modified PP with activated talc powder greatly improves the rigidity of the material and overcomes the warping deformation of the washing machine impeller. At the same time, toughening agents and talc powder are added to make the PP spherulites smaller, have good dimensional stability, and improve the mold quality. Strength, elastic modulus and impact resistance, increase firmness and reduce shrinkage.

After talc powder modifies polypropylene, the mechanical properties and planar structure of the talc filler have a great influence on the crystalline arrangement of polypropylene. Slightly increasing the amount of talc powder will change the crystalline state of polypropylene. Change is the main cause of macro effects.

Talc acts as a nucleating agent for PP. In addition, filling PP with talc powder can greatly improve the bending strength and notch impact strength of waste PP plastics, and reduce the molding shrinkage of waste PP, in addition to a slight decrease in the elongation at break. Talc powder has a great effect on improving the rigidity and heat resistance of PP. When PP with high rigidity and high heat resistance is required, talc powder is often used to fill PP. The dimensional stability of talc-filled PP is better than that of calcium carbonate-filled PP. Therefore, talc-filled PP has a wide range of uses and has been dominantly used in automobiles, home appliances and other fields.
