Chemical Resistance

Chemical Resistance

PE shows high resistance to chemical attacks with its non-polar structure like high molecular weighted hydrocarbons. PE cannot be decayed, worn out, or weakened mechanically, by electrical or chemical reactions.
PE shows high resistance to acids, alkaline solutions, solvents, alcohol and water, and low resistance against oxidant acids, ketones, aromatic hydrocarbons and chloral hydrocarbons.
Level of chemical resistance, depends on chemical’s concentration, temperature and working pressure. This three specifications determine pipe’s life.

 

A: High Resistance - B: Limited Resistance - C: No Resistance
