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
