Description

Product: polyethylene

Polyethylene is half crystallization thermoplastic materials. Their chemical structure, molecular weight, the degree of polymerization and other performance to a large extent are dependent on the use of polymerization methods. Polymerization method determines the type of branch chain and a chain degrees. Depending on the chemical structure of polymer crystallinity and processing conditions.

Chemical properties：

Polyethylene has excellent chemical stability, resistance at room temperature hydrochloric acid, hydrofluoric acid, phosphoric acid, formic acid, amine class, sodium hydroxide, potassium hydroxide etc all kinds of chemical substances, and nitric acid of sulfuric acid polyethylene strong damage. Polyethylene easy to light oxidation, thermal oxidation, ozone decomposition in ultraviolet ray, under the action of degraded to a well of polyethylene, carbon black light shielding effect. By radiation can occur after crosslinking, broken chains, formation unsaturated groups and reflect.
