Due to its thermal and mechanical properties, this semi-crystalline material belongs to the polymer group of standard plastics. PE-UHMW belongs to the family of polyethylenes and polyolefins.
In the group of polyolefins, the homopolymeric Polyethylene-Ultra-High-Molecular-Weight stands out for its very low density, very good sliding properties and at the same time high toughness. The chemical resistance is very high. Due to the very low dielectric loss factor, high-frequency welding is not possible. However, all other appropriate welding procedures should work without problems. The continuous operating temperature for PE-UHMW ranges between -150 °C and approximately +90 °C. Our round rods in natural, black and blue colour comply with the food contact regulations according to 10/2011/EC.
