What is PEHD?
PEHD stands for Polyethylene High Density. PEHD is a thermoplastic with high wear resistance and chemical resistance and is therefore suited to machine parts and plastics for food production.
If you order PEHD from Induflex, the standard material supplied is FCM.
Several companies produce PEHD, and the material is known under several brand names such as Polystone® og Tivar®.
What can one use PEHD for?
PEHD is typically used in the food industry where it is made into slide rails or toothed wheels, for example. PEHD can often be used in extremely cold environments, right down to - 200 °C for PEHD 1000 and PEHD 2000.

Characteristics and advantages of PEHD
PEHD has a relatively low volume weight.
There are several types:
- PEHD 300 (HD)
- PEHD 500 (HMW)
- PEHD 1000 (UHMW)
- PEHD 2000 (UHMW)
The higher the molecular weight of a PEHD, the lower friction and higher wear resistance of the material. Yet the solution is not always to move up the scale, as the material becomes softer. If you are in doubt as to the type of PEHD best suited to your project, we will be happy to advise you.
Irrespective of type, PEHD has a number of general advantages:
- High wear resistance
- Good chemical resistance
- Minimal water absorption
- A good electrical insulation material
- Good friction
- Ability to withstand low temperatures
PEHD is not UV-resistant, however in black it performs better than other colours. PEHD is not suited to printing, which places high demands on mechanical stability.
We perform CNC turning and machining of your PEHD products and machine parts.
PEHD is supplied in sheets and rods, in many colours such as natural, black, yellow, green, red and blue.
PEHD at Induflex
PEHD stocks in our warehouse stand at the ready to produce your items. As standard we keep sheets and ranks of PEHD 300 and PEHD 1000 in natural and black, as well as sheets of PEHD 300, PEHD 500 and PEHD 1000 from 1 mm – 120 mm in natural, black, yellow, blue and green.
If you would like a particular colour or type, this can be ordered for delivery to you.
