Description

Polyethlene 

English name: Polyethylene (PE) as the proportion of 0.***0.*6 g cubic centimeter molding shrinkage rate: 1.5 3.6% molding temperature: ******0 ℃classfication:
HDPE: high density polyethylene, low pressure polyethylene
LDPE: low density polyethylene, high pressure polyethylene

Polyethylene odorless, non-toxic, feel like wax, has good low temperature resistance performance (minimum use temperature up to *0 ~ **0 ℃), chemical stability, ability and erosion (not most has the nature of the oxidation resistance acid), under normal temperature insoluble in general solvent, water, but because of its small for linear molecules can slow soluble in some organic solvent, and don't happen swelling, electric insulation good performance; But for environmental stress (polyethylene chemical and mechanical function) is a very sensitive, heat ageing sex differences

Features: corrosion resistance, electrical insulation (especially high frequency insulation) is good, can chlorinated, chemical crosslinking, radiation crosslinking modification, can use glass fiber reinforced. Low pressure polyethylene melting point, rigid, hardness and high strength, small water imbibition, good performance and resistance to the radioactive; High pressure polyethylene softness, elongation, impact strength and permeability is better; Ultra high molecular weight polyethylene impact strength, high resistance to fatigue, low pressure polyethylene production wear-resisting. Suitable for corrosion resistant parts and insulation parts; Suitable for high pressure polyethylene thin films, etc.; Ultra high molecular weight polyethylene suitable for making suspension, wear-resisting and transmission parts.
