Polyethylene (PEHD)

If you are looking for a thermoplastic with high wear resistance, PEHD is a good choice. We offer processing of PEHD in many colours and various types. Your plastic items can be produced in exactly the colour and with exactly the features that best meet your requirements.

HDPE

What is PEHD?
PEHD stands for Polyethylene High Density. PEHD is also known as HDPE (High Density Polyethylene).
PEHD is a thermoplastic with high wear resistance and chemical resistance and is therefore suited to machine parts and plastics for food production.
PEHD can be supplied in sheets and circular blanks in many colours such as nature, black, yellow, green, red and blue.
What can one use PEHD for?
PEHD is typically used in the food industry such as:
Slide rails，Toothed wheels，Rolls，Support，Belts，Screen enclosure，Bottom bend
Cutting pads.
PEHD is also used for products such as:
Plastic bags ，Equipment for playgrounds Bins，Fuel tank for cars.
PEHD can often be used in extremely cold environments, right down to - 200 °C for PEHD 1000 and PEHD 2000. It is therefore used in skating rinks.
Read more about the various temperature scenarios in our table on technical plastic.
PEHD has a relatively low volume weight.

There are several types:
PEHD 300 (HD) - also known as HDPE 300
PEHD 500 (HMW) - also known as HDPE 500
PEHD 1000 (UHMW) - also known as HDPE 1000
PEHD 2000 (UHMW) - also known as HDPE 2000
The number in the name indicates the molecular weight (molecular chain's length).
The lower the number the lower molecular weight.
For instance PEHD 300 has a lower molecular weight than PEHD 2000.
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.

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.
PE also comes as LDPE (Low Density Polyethylene) and MDPE (Medium Density Polyethylene). Both LDPE and MDPE are mainly used for packaging.
