Polystone MR is an ultra-high molecular weight polyethylene (UHMWPE) grade characterised by excellent abrasion resistance and a low coefficient of friction. With a dynamic coefficient of friction of 0.13, it minimises sliding wear and energy loss in moving parts.
This engineering plastic maintains its mechanical properties across a wide temperature range from -100°C to 80°C and offers high resistance to many chemicals. Dotmar supplies Polystone MR in sheet format, ready for precision machining and fabrication to meet specific industrial requirements.
Key Features
- Low coefficient of friction (0.13) for reduced wear
- High abrasion resistance for long service life
- Service temperature range from -100°C to 80°C
- High chemical resistance to many industrial chemicals
- Supplied in sheet format for machining and fabrication
