高密度聚乙烯板材

高密度聚乙烯板材
  高密度聚乙烯板材的主要材料高密度聚乙烯，英文名称为“High Density Polyethylene”，简称为“HDPE”。HDPE是一种结晶度高、非极性的热塑性树脂。原态HDPE的外表呈乳白色，在微薄截面呈半透明状。PE具有优良的耐大多数生活和工业用化学品的特性。某些种类的化学品会产生化学腐蚀，例如腐蚀性氧化剂（浓硝酸），芳香烃（二甲苯）和卤化烃 （四氯化碳）。该聚合物不吸湿并具有好的防水蒸汽性，可用于包装用途。HDPE具有很好的电性能，特别是绝缘介电强度高，使其很适用于电线电缆。中到高分子量等级具有好的抗冲击性，在常温甚至在-40F低温度下均如此。
   High density polyethylene sheet main materials of high density polyethylene, English name is "High Density Polyethylene ", referred to as the "HDPE ". HDPE is a high degree of crystallinity, non-polar thermoplastic resin. The original state HDPE appearance is milky white, in the small section are somewhat translucent. PE has good resistance to most living and industrial chemical characteristics. Some kinds of chemicals have a chemical corrosion, such as corrosive oxidant ( nitric acid ), aromatic hydrocarbon and halogenated hydrocarbon ( xylene ) ( CCL ). The polymer does not absorb water and has good waterproof steam, can be used for packaging purposes. HDPE has a very good electrical properties, in particular the dielectric strength is high, make it very suitable for wire and cable. In the high molecular weight grade with excellent impact resistance, in room temperature even in -40F low temperature are so.
