Polyethylene (PE) Machining
A Guide to Polyethylene CNC Machined 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
- 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
