Chemical, weathering, and abrasion resistance for PE

Due to its non-polar nature as a hydrocarbon of high molecular weight, polyethylene shows a high resistance against chemical attack. PE is resistant to acids, alkaline solutions, solvents, alcohol and water. Fat and oil swell PE slightly. PE is not resistant against oxidising acids, ketones, aromatic hydrocarbons and chlorinated hydrocarbons. For additional information, please refer to the detailed list of chemical resistance tool on the GF Piping Systems website. If polyethylene is exposed to direct sunlight over a long period of time, it will, like most natural and plastic materials, be damaged by the short wave UV portion of sunlight together with oxygen in the air, causing photo-oxidation. Because of this, GF black polyethylene grades are effectively stabilised against UV light by adding carbon black. PE also has excellent resistance against abrasion. As a result, PE piping systems are used in numerous applications for transporting solids and...
