Polyethylenes are semi-crystalline materials with excellent chemical resistance, good fatigue and wear resistance, and a wide range of properties (due to
differences in length of the polymer chain.) Polyethylenes are easy to distinguish from other plastics because they float in water. Polyethylenes provide goo
resistance to organic solvents, degreasing agents and electrolytic attack. They have a higher impact strength, but lower working temperatures and tensile
strengths than polypropylene. They are light in weight, resistant to staining, and have low moisture absorption rates.
