国内涂覆级 LDPE 市场及应用概述

摘要

The paper summarized the national market and application situation of LDPE special resin for coating , analyzed the performances differences between two types of LDPE crude materials for coating which were produced respectively by autoclave and tubular process . Requirements of the consumers on LDPE special resin for coating were lesser crystallite and the smallest neck in.The LDPE special resin for coating made from autoclave process possessed higher attractiveness than the resin made from tubular process , consumption of the latter was less.Considering great market demand lack of domestic LDPE special resin for coating and fas-ter growth rate of the coating articles , national companies should increase research and develop-ment efforts and develop new LDPE resins for coating with better properties.%分析釜式法与管式法生产的涂覆级LDPE的性能差异，综述国内涂覆级 LDPE 的市场及应用概况。结果表明，用户对涂覆级LDPE的要求是较少的晶点及尽可能小的缩幅，釜式法生产的涂覆级 LDPE在用户中具有较高的认知度，管式法生产的涂覆级LDPE用量较少。据此提出研发建议。
