CAS号:

性质: 由1-丁烯均聚或与少量其他α-烯烃共聚而成的一种热塑性树脂。结晶度50%~55%,密度0.91~0.915g/cm3。拉伸强度28~32MPa,悬臂梁缺口冲击不断,邵氏硬度D32~55。脆化温度<-187℃,维卡软化点113~121℃。有突出的耐环境应力开裂性,而且抗蠕变性、耐磨性、耐化学药品性、耐热性好,可在-30~100℃下长期使用。可采用齐格勒-纳塔催化剂,经浆液聚合、本体聚合或气相聚合制得。在加工成制品时存在晶形转变问题。在室温和常压下,大约5~7天后才逐渐由不稳定的II型晶态转变成稳定的I型晶态。主要用于热水管、工业用管、气体管等,用以代替铜管或铝管,也用于薄膜,板材、容器、密封件、单丝等。
