What is PE-UHMW?
Very-high-molecular-weight polyethylene - UHMW-PE or PE-1000 - is a very strong material without PFAS. Its molecular chain is very similar to that of PTFE. However, in the case of UHMW-PE, the carbon atoms are bonded to hydrogen atoms instead of fluorine atoms. This difference also varies the possible applications.
Properties of PE-UHMW:
- Non-stick surface
- Low coefficient of friction of approximately 0.2 to 0.25 => very good sliding properties, even during dry operation.
- Very good wear resistance, even without load.
- Excellent chemical resistance to most solvents, acids and bases.
- Temperatures: from -260°C to approx. 80°C.
- Physiologically harmless (food approvals, e.g. according to the FDA).
- No thermal expansion => multifunctional solutions possible.
