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.
