Engineering Plastic

Polyethylene Engineering Plastic

High-quality general-purpose engineering plastic materials; the chemical name is polyethylene. It’s available in a range of grades and forms to suit many applications.


The machining of polyethylene is uncomplicated provided the component tolerances allow for polyethylene’s relatively high coefficient of thermal expansion and tensile elongation values. Full machining instructions are available on request.

Chemical Resistance

HD-PE has extremely good resistance to aqueous solutions of acids, alkalis and salts and also in alcohol and many solvents. Slight swelling may be caused by permanent contact with grease, oil and wax, but generally not enough to limit the use of the material. Aromatics and halogenated hydrocarbons will cause a reduction in useful working life. The material has no resistance to strong oxidising agents such as nitric or chromic acids, and halogens. The UHMWPE grade has even better chemical resistance; strong oxidising agents only cause surface swelling.

Typical Applications

Commercial applications for this engineering material include:

  • Transport containers
  • Pump and valve parts
  • Tank construction
  • Medical components
  • Gaskets
  • Slide profiles
  • Food industry parts

We stock Polyethylene in round bar, round tube and hollow bar.
