Semi-Finished Products  PE sheet/rod/tube 


Polyethylene (PE)

This polymer known as a thermoplastic can be manufactured in 4 commercial types:

1.       Low density

2.       Medium density

3.       High density

4.       Ultra high molecular weight

 

Product strengths:

·         High chemical resistance typical of polyolefin

·         Abrasion resistance

·         Low coefficient of friction

·         Low specific gravity

·         Suitable for easy machining

·         Good shock resistance even at low temperatures

 

 

Product weakness:

·         Inferior thermal and mechanical properties, e.g. tensile strength, elasticity and compactness, in comparison with other engineering polymers.

·         Typical polyethylene are more rigid than HMW-PE but less resistant to impact

 

Applications:

Mechanical: Used for bearings and mechanical parts not subject to high pressure even in water due to low coefficient of friction and non-hygroscopic.

Electrical: Waterproof and excellent dielectric properties.  

Chemical: Good acid and alkali resistance make it suitable for use in this industry.

Food contact: Physiologically inert and food contact approved by most standard organizations including FDA and widely used in machinery lines and pumps for liquid foods.
