Tianwei new materials, focusing on the research and production of atomized alloy powder
Micron-level composite material filled stainless steel powder
Adding metal powder to polymers is primarily to alter the appearance or physical properties of the polymer. The growth in the automotive industry and related fields requiring lightweight, high-performance parts has led to an increase in the use of polymer-based composites. Many of these composites contain metal powder to give them the same metallic appearance as the parts they replace.

Product Details
Adding metal powder to polymers is primarily to alter the polymer's appearance or physical properties. The growth in the automotive industry and related fields' demand for lightweight, high-performance parts has led to an increase in the use of polymer-based composites. Many of these composites contain metal powders to give them the same metallic appearance as the parts they replace.
Tianwei's micron-sized stainless steel powder is filled into plastics by customers according to the end use, creating various shapes and sizes. The physical properties and functions of the affected polymers include: conductivity; thermal conductivity; electromagnetic shielding; anti-static surface; corrosion resistance; wear resistance.
The most widely used application of these composites is the use of stainless steel powder to fill polytetrafluoroethylene as a sealing material. It has a good reputation in practical applications. Filling it with snowflake-shaped micron-sized stainless steel powder makes it have a finer texture and better holding performance. This series of powders has been successfully exported to many countries such as Japan, Germany, and the United States, and the application volume is increasing year by year.
