上海慧友防腐技术工程有限公司研制开发的辐射交联聚乙烯热收缩材料是采用特殊配方的聚乙烯作原料 ,经热熔延压成板带材 ,用高能射线辐照使其原直链分子结构变成网状交联状态 ,再经后处理工艺制成具有“记忆”效应的热收缩材料。该材料为无污染的绿色材料 ,它的问世改变了我国
Shanghai Huiyou anti-corrosion Technology Engineering Co., Ltd. research and development of radiation cross-linked polyethylene heat shrinkable material is the use of special formulations of polyethylene as raw material, hot-melt pressed into plate strip, with high-energy radiation to the original straight chain molecules Structure into a network of cross-linked state, and then made by post-processing has a “memory” effect of heat shrinkable material. The material is pollution-free green material, its advent has changed our country
