JH-220 type polytetrafluoroethylene (PTFE) micro powder is a low-molecular-weight micron-sized polytetrafluoroethylene white powder prepared by a special method, with a molecular weight of 80,000~100,000. It not only basically maintains the excellent characteristics of PTFE, but also has many unique properties, such as high crystallinity, good dispersion, and easy mixing and adding, so it is widely used in the blending modification of polymer materials.
Adding this product to engineering plastics can significantly improve the wear resistance,lubricity, non-stickiness and flame retardancy of the base material, and significantly improve the performance of the base material. JH-220 can be used between -190℃ to 300℃.
JH-220 is usually used as a processing aid, and can also be used alone as a lubricant. But it cannot be used to replace high molecular weight PTFE suspension or dispersion resin for extrusion or compression molding.
