HDPE管材

HDPE管材
   HDPE是一種結晶度高、非極性的熱塑性樹脂。原態HDPE的外表呈乳白色，在微薄截面呈半透明狀。PE具有優良的耐大多數生活和工業用化學品的特性。某些種類的化學品會產生化學腐蝕，例如腐蝕性氧化劑（濃硝酸），芳香烴（二甲苯）和鹵化烴 （四氯化碳）。該聚合物不吸濕并具有好的防水蒸汽性，可用于包裝用途。HDPE具有很好的電性能，特別是絕緣介電強度高，使其很適用于電線電纜。中到高分子量等級具有抗沖擊性，在常溫甚至在-40F低溫度下均如此。
   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.
