Product introduction
JHT-200 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
10,000~30,000. 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. JHT-200 can be used between -190℃
to 300℃.
JHT-200 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.

Main Application
JHT-200 is mainly used as a processing aid for various thermoplastic/thermosetting plastics, rubber and elastomers. It can reduce the friction coefficient of the material surface, improve the wear resistance of the material, prevent the surface of the material from being scratched, and at the same time perform internal lubrication and mold release. It can also improve the anti-adhesive and anti-friction properties of the resin, and avoid surface defects and fouling of injection molded parts. The amount of JHT-200 added is generally between 5-20% (by weight).
The plastic fields mainly used by JHT-200 include nylon (PA), polyoxymethylene (POM), polycarbonate (PC), polyester, polyimide (PI), polyphenylene sulfide (PPS), polyether ether (PEEK), polysulfone, etc.
Package and transportation
JHT-200 is packed in composite paper bag, net weight: 25kg/bag, convenient for transportation and storage.
This product is non-dangerous, please store it away from fire sources and strong oxidants. Do not smoke when operating the PTFE powder, to avoid some toxic gases produced by the burning of the PTFE powder.
