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
· 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
· 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
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.
