Talc powder is an industrial raw material of magnesium silicate minerals, which is made by directly crushing natural talc ore (raw material of talc powder) sorted according to purity grade. The common fineness levels of talc powder include 325 mesh, 400 mesh, 600 mesh, 800 mesh, 1250 mesh to 10000 mesh. Talc powder is usually packed in woven bags and composite paper bags. Talc has the physical and chemical properties such as low hardness, lubricity, fire resistance, acid resistance, insulation, high melting point, chemical inactivity, good hiding power, softness, good luster, and strong adsorption. Talc powder is mainly used in plastics, rubber, paper making, paint and coating, chemical filler and rubber products anti-sticking agent and other industries.
TP-555L has high purity and low whiteness. It can be added to plastics as a modification filler to obtain better performance. It is suitable for plastic products with no requirements for whiteness.
Due to its low whiteness, this product has a high cost performance ratio and is widely used in automobile exterior trim parts, such as mudguards, bumpers, etc. which can then obtain higher toughness, strength, and flexural performance . Especially at low temperatures, the products modified by TP-555L can obtain better bending strength, and thus be safer and more reliable during impact.
TP-666L/TP-888L are upgraded from TP-555L, with higher purity and fineness. They can be used for dark interior and exterior trim products of automobiles, and effectively improve product performance after being applied in different resin systems.
