HDPE

GEHR HDPE®

High Density Polyethylene has a good chemical resistance to almost all acids and bases, detergents and hot water. HDPE has good insulation properties and is easy to weld. The operating temperature is from -58 °F to +194 °F.

Properties:

  • low density
  • high toughness (also at low temperature)
  • high elongation
  • 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

Applications:

Transport containers, pumps and valve parts, parts in the tank construction, components with medical applications, gaskets, sliding profiles, components for the food industry.

GEHR HDPE-ELS® (electrically conductive)

A variant of HDPE with improved electrical conductivity.
Volume resistivity ≤ 104 Ω x cm
Surface resistivity ≤ 105 Ω
