PE300
Antiacids
Rods, sheets, tubes
Description
Molecular weight 300.000 polyethylene similar to the type 500 with higher rigidity and lower resistance to continuos shocks. The applications are similar to those of PE 500, being more commonly specified when a slightly more rigid material is required.
Features
- Chemical: high chemical resistance typical of the polyolefins. Shock resistance, good even at low temperature
- High abrasion resistance
- Low friction coefficient
- Low specific gravity
- Easy machinability
- Colour natural
Weak Point
- Compared to the engineering plastics it has lower thermal and mechanical properties: tensile stress, flexural and compressive strength, etc. Compared to high molecular weight PE, it is more rigid and its resistance to continuous shock is therefore lower.
Application
Mechanical: The low friction coefficient and its non hygroscopicity make it suitable for use as a bearing or mechanical parts with low loads, even when operating in water -
Food contact: physiologically inert, it is approved for food contact by the most important standards organisations. Thanks to this feature, it is widely used for components in food machinery, pumps for liquid food etc. 
Electrical: very good dielectric properties, weatherproof -
Chemical: thanks to the high resistance to acids and alkali it is used for components in the chemical industry
