[材料性能] Material performance
EVOH （乙烯—乙烯醇共聚物）是一种具有链式分子结构的结晶性无规共聚物，是一种新型的阻隔材料。EVOH树脂是目前世界上工业化生产的三大阻隔树脂之一 （PVDC\EVOH\PA） 是二种集乙烯聚合物的加工型和乙烯醇聚合物的隔主性于一体的新型高分子材料。其阻氧性 （阻O2\水、CO2） 比 （聚酸胺） 高100倍，比PE\PP高10000倍，比日前常用的醇阻氧性材料PVDC（聚偏二氯乙烯）高10倍以上。此外，EVOH的透明性、机械挤度、伸缩性、耐寒性都非常优越。EVOH阻氧材料，提高了阻氧性能，彻底解决了透氧问题。
采用日本进口粘接性很强的专业粘接剂，使PB材料与阻氧层之间永不脱层。
（EVOH）有极高保证管道系统运行的安全性和畅通性。彻底解决了渗氧造成的氧化腐蚀问题，从而增加了采暖管道系统的使用寿命。
阻氧PB它具有很高的耐温耐压性能、持久性、化学稳定性和可塑性，无臭无味,对水质不造成二次污染，是世界上尖端的化学材料之一，该材料重量轻；柔韧性好；耐腐蚀；不结垢；施工简便等优点。可在 -30℃-100℃下长期使用，使用寿命长达 50-100年。
