Polystone UHMWPE - The Great All-Rounder
Ultra high molecular weight polyethylene (UHMWPE), is the great all-rounder in thermoplastics. It has extremely long molecular chains, with a molecular weight numbering in the millions, usually between 2 and 6 million.
Rochling Polystone UHMWPE exhibits a molecular weight of over 7 million which is significantly more than other commercial grades of UHMWPE available. This results in an extremely tough material that exhibits an impressive array of characteristics. A higher molecular weight of Polyethylene has a significant influence on important technical properties.
Polystone UHMWPE offers:
- Highest impact strength, even at low temperatures
- High resistance to corrosive chemicals
- Weatherproof - Extremely low moisture absorption
- Very low coefficient of friction
- High dielectric resistance
- Lightweight and easy to handle
- Self lubricating - No need for lubricating agents that could cause contamination
- Highly resistant to abrasion - 15 times more resistant to abrasion than carbon steel
- Coefficient of friction comparable to that of Teflon, but with better abrasion resistance
- Physiologically inert - Odourless, tasteless and non-toxic
- Low cost per kg when compared to metal
- Pressed and planed for optimum flatness
