PE 介绍
HDPE 高密度聚乙烯，
英文名称为:“High Density Polyethylene”。
物化性质
熔点约为131℃，密度0.941~0.960它具有良好的耐热性和耐寒性，软化点125~135℃脆化温度-70℃，使用温度可达100℃耐磨性能也较好。电绝缘性能、韧性、耐寒性都很好，但略差与低密度聚乙烯。收缩率：1.5%到4%
HDPE high density polyethylene,
Physical and chemical properties:
Melting point of about 131 ℃, density of 0.941 ~ 0.960 that it has
good heat resistance and cold resistance, softening point of 125 ~
135 ℃ embrittlement temperature of -70 ℃, 100 ℃ temperature up to
have better wear resistance. Electrical insulation, toughness, cold
resistance are good, but slightly worse with the low-density
polyethylene. Shrinkage: 1.5% to 4%
MDPE 中密度聚乙烯，
英文名称 medium density polyethylene,
物化性质
密度0．926～0．940g／CC，软化温度110~115℃，除兼有高、低密度聚乙烯的性能外，还具有优良的抗应力开裂性、刚性及耐热性。脆化温度-140~-100℃
Physical and chemical properties:
Density of 0.926 ~ 0.940g/CC, softening temperature of 110 ~ 115 ℃,
except both high and low density polyethylene of the performance,
but also has good resistance to stress cracking resistance, rigidity
and heat resistance. Brittleness Temperature -140 ~ -100 ℃
LDPE 低密度聚乙烯
英文名称：low density polyethylene。
物化性质：
耐寒性较好；在-70~-80℃仍能保持稳定。密度范围为0.916～0.922 软化点90～100℃较低,透光率85%.
Physical and chemical properties:
Good cold tolerance; to -70 ~ -80 ℃ still remain stable. Density
range of 0.916 ~ 0.922 90 ~ 100 ℃ softening point lower rate of 85%
light transmission.
