BP24S
PVA
长春粉末
中国台湾长春是水溶性生物可降解聚合物，固体，有粉末和颗粒两种形态。是一种水溶性环保型高分子聚合物，无毒无污染，具有很好的成膜性能，乳化性能、粘结性能和纺丝性能。它形成的膜具有优异的接着力，耐溶剂性，耐摩擦性，伸张强度与氧气阻绝性。因为同时拥有亲水基及疏水基两种官能基，因此具有界面活性的物质，所以可以作为高分子乳化，悬浮聚合反应时的保护胶体。

二、主要用途(Application)
PVA当作水泥添加剂可有效地增加水泥的接著力，流动性及减缓水泥表面干燥时间，增加涂工适性，防止水泥涂布面的龟裂，适合于墙壁，天花板粉饰及瓷砖的贴合。
S-series is specially designed for cement additives and building industy.They improve plaster properties such as flexibility,water retention,ａnd increase plaster viscosity as well.In addition,they do not only reduce the friction of plaster but also enhance its working capacity and quality.(prevent cracking and shedding of plaster,increase adhesion and smothness of cement.)To mix desired amount of PVA with cement well bifore water is added prevents the lumping of PVA.
