PTFE Micropowder Engineering Plastic Grade
1. Product Introduction
PTFE micropowder could improve the friction resistance of engineering plastics obviously, reduce the friction coefficient, improve self-lubrication and reduce noise. PTFE micropowder can be used in gears, bearings, pulleys and other parts which need high wear resistance requirements, and can also be used to replace metal parts for lubrication function, thus reducing the weight and cost of the parts.
It could be widely used in engineering plastics such as polymethylol (POM), nylon (PA), polycarbonate (PC), polyether ether ketone (PEEK), polyester (PET), polyphenylene sulfide (PPS), etc. Special grade can be used in high temperature (420℃) molding and processing of engineering plastics.
