Polyethylene rod PE series

The homopolymeric Polyethylene High Density has a very low density combined with high toughness. Due to its good chemical resistance, PE-HD is insensitive to most acids, bases, many organic solvents and hot water. The material is a good electrical insulator and, apart from high-frequency welding, can shows good weldability. The continuous operating temperature for PE-HD in natural colour ranges between -50 °C and approximately +90 °C. GEHR PE-ELS® This polymer is a variant of PE-HS with improved electrical conductivity. By means of a special conductive carbon black, the volume resistance could be reduced to ≤104 Ω and the surface resistance to ≤105 Ω. PROPERTIES GEHR PE-HD® Low density High toughness (also at low temperature) High elongation at break Very good electrical and dielectric properties Very low water absorption Low steam permeability High chemical resistance Good protection against stress cracking Food safe Soft surface (low tensile strength) HF welding not recommended Natural color is not weather resistant
