Polyethylene (PE) Machined Parts

A Guide to Polyethylene CNC Milled & Turned Parts: Properties, Applications and Design Considerations

What is Polyethylene?

Polyethylene (PE) also known as Polythene (IUPAC name polyethene) is a semi-crystalline thermoplastic. PE offers high levels of toughness with low strength and hardness. Its versatility has made it one of the most popular plastics globally.

There are many well-known variants of Polyethylene – a breakdown of the most common can be found in the ‘notes for designers’ tab below. 

Main Attributes of Polyethylene:

The attributes of polyethylene depends on the type although the below properties are largely universal:

  • High toughness
  • Excellent chemical resistance
  • High impact strength
  • Low moisture absorption
  • Very good electrical insulation
  • Excellent machinability
  • Most grades suitable for food contact
  • Lightweight
  • Good resistance to high energy radiation
  • Good stability to temperature
  • Lower thermal and mechanical properties (tensile stress, flexural and compressive strength) than engineering plastics
  • Relatively low cost
