Superfine composite reinforcing powder
.jpg)
Composite reinforced powder is specialized in inorganic reinforced powder produced in the rubber and plastic industries. It can improve the hardness, toughness, bending strength, weather resistance, and scratch resistance of material products. It not only increases weight and strengthens, but also effectively reduce production costs.

In plastics: can replace part of asbestos glass fiber for reinforcement. In epoxy, phenolic, thermosetting polyester, polyolefin and other plastic applications, it is mainly used to improve tensile strength, flexural strength, thermal stability and surface color.
In rubber: it can replace part of carbon black and white carbon black, reduce the production cost of rubber products, improve the mechanical properties, tensile strength, tear strength, elongation at break, abrasion resistance and other properties of rubber, and endow the rubber itself with No special features.
