Talc powder masterbatch is a kind of plastic modified filler, which mainly consists of talc powder. Haicheng talc powder is granulated by mixing with polymer or other carriers. It is mainly used to improve the functions of rubber, plastic resin and so on. It can obviously improve the stiffness, high temperature creep resistance and heat resistance of filling materials.

Talc powder masterbatch is a kind of plastic modified filler, which is composed of talc powder, which is mixed with polymer or other carriers to granulate. It is mainly used to improve the functions of rubber, plastics and resins. Compared with talc powder, talc powder masterbatch has better processing function and improves the problem of talc powder evaporation.

Talc is a water-bearing silicate deposit with layered structure. Chemical formula: Mg3 (Si4O10) (OH) 2. Its chemical composition is 31.8% MgO, 63.37% SiO 2 and 4.7% H 2O. It often contains a few elements such as Fe and A1. The density of talc is 2.7-2.8g/cm, and its hardness is the smallest one in ore filling guess. Its Mohr hardness is 1. It has a soft and slippery feeling. Its colours are white, grey green, Milky white, light red, light blue, light grey, etc., with pearl or fat luster. Associated water can be lost at 380-500 (?) C and crystalline water can be lost at 800 (?) C. Talc is slightly alkaline in water with a pH of 9.0-9.5.

The talc has a layered structure, and the adjacent layers are combined by a weak van der Waals force. When the external force is applied, it is very easy for the adjacent two layers to slip or separate from each other. Therefore, the basic shape of talc particles is flaky or scaly.

The lamellar structure of talc powder has greatly improved some functions of talc powder filled plastics. Some people regard talc powder as reinforcing filler. The primary talc powder can improve the stiffness of filling materials and creep resistance at high temperature. When talc particles are placed along the direction of material movement during processing, according to the principle of minimum resistance, they are basically placed in sheet shape, from small pieces to large pieces. Therefore, data stiffness can be significantly improved in a specific direction. Secondly, talc powder can significantly improve the heat resistance of filling materials. The thermal deformation temperature used to measure the heat resistance of data refers to the temperature when the sample is tortuous to a certain degree under load effect, and the sheet talc powder can improve the thermal deformation temperature of data in a specific direction

Among the silicon filling guesses, talc powder is the cheapest and can reduce costs.
