What kind of plastic talcum powder is good?
As a plastic filler, talc can not only save the use of resin, but also significantly improve the physical properties of the product and play a reinforcing role.
Sufficient fineness of talc can significantly improve product stiffness, impact strength, creep resistance, hardness, surface scratch resistance, heat resistance and heat distortion temperature. For the modification of polypropylene plastics for automobiles and household appliances, the price/performance ratio of talc is unmatched by any other non-mineral material. Talcum powder has a significant reinforcing effect on plastics, but not all talc powder products have a reinforcing effect. The enhancement effect varies significantly depending on the talc quality. It is difficult to come up with a uniform and specific standard for talc used in the plastics industry. (The general principle is: try to use pure talc products with suitable particle size, and do not need to be as fine as possible.) The source of talc raw materials must be fixed, and the quality of talc powder, especially particle size distribution, wet whiteness and color tone, must be stable and continuous. Given the variety of talc products, the correct use of talc products for best results requires technical support from the manufacturer. When choosing talc, at least consider the "four degrees" of talc itself, namely: purity, whiteness, flakes and fineness.
In general, in order to evaluate the quality of talc products, at least the above four factors should be considered. Judging quality by just a single metric may not be comprehensive. It is controversial if the quality of talc is judged solely on the basis of the average particle size.
