Talc powder as a plastic filler can increase the hardness of products

Talc with lubricity, sticky, flow resistance, fire resistance, acid resistance, insulation, high melting point, chemical inertness, good covering power and soft, good luster, strong adsorption force and other excellent physical and chemical properties.

In many applications, talc can not only play the role of general fillers to reduce the cost of products, but also can significantly enhance the performance of these products. As a filler, talc is widely used in papermaking, plastic, paint, ceramics, cosmetics, medicine, rubber, agricultural products, fertilizer and other industries.

Haicheng talc is not lively, soft and greasy, it is a typical plate filler. Its crystalline monoclinic system, a six square or rhombic, often flaky, scaly or density lump, flake cleavage completely, talcum powder and chemical composition of hydrous magnesium silicate, is composed of basic unit, formed on the lower again, by weak van der Waals force between the layers combination, applying force so easy to peel, slippage between layers.

Talc powder, as a plastic filler, can improve the hardness, fire resistance, acid and alkali resistance, electric insulation, dimension stability and creep resistance of products. However, due to the different chemical composition and crystalline structure of talc from different producing areas, the properties of filling plastics are also different. Talc powder is a kind of plate filler, so it can be used to process large and flat products with large rigidity and small anisotropy.
