新研博美PEG衍生物种类介绍

PEG衍生物依分子量不同而性质不同，从无色无臭黏稠液体至蜡状固体。分子量200～600者常温下是液体，分子量在600以上者就逐渐变为半固体状，随着平均分子量的不同，性质也有差异。从无色无臭粘稠液体至蜡状固体。随着分子量的增大，其吸湿能力相应降低。本品溶于水、乙醇和许多其它有机溶剂。蒸气压低，对热、酸、碱稳定。与许多化学品不起作用。有良好的吸湿性、润滑性、粘结性。无毒，无刺激。平均分子量300，n=5～5.75，熔点-15～8℃，相对密度1.124～1.130。平均分子量600，n=12～13，熔点20 ～25℃，闪点246℃，相对密度1.13 (20℃)。平均分子量4000，n=70～85，熔点53～ 56℃。陕西新研博美生物科技有限公司的PEG衍生物种类如下：
