Polyethylene (PE) Plastic Machining
A Guide to Polyethylene CNC Machined Parts: Properties, Applications and Design Considerations
What is Polyethylene Plastic?
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 variants of Polyethylene plastic – the most well-known being HDPE, LDPE, UHMWPE and HMWPE. A breakdown of these can be found in the ‘notes for designers’ tab below.
Main Attributes of Polyethylene Plastic:
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
Detailed information about Polyethylene for designers can be found in the tabs below. Please note: this information is provided as a guide only.
