PVA产品拥有水溶性、造膜性、粘接性、乳化性、耐油性、耐药品性等特性，被使用于纸张加工剂、粘接剂、氯乙烯聚合分散剂以及汽车挡风玻璃的中间膜原料等各种用途。除了通用产品之外，还提供赋予了各种特性的高功能聚合物产品。
可乐丽PVA的性质
可乐丽PVA是白色粒状的水溶性合成树脂，化学名称为PolyvinylAlcohol，简称PVA。PVA的主要性质是由分子的醇解度和聚合度而定的，并具有如下性质：
1、水溶性：易溶于水，不溶于几乎所有的有机溶剂
2、水溶液的粘度：PVA水溶液的粘度是随聚合度和温度以及溶液浓度变化而变化的
3、成膜性：PVA水溶液易成膜，其皮膜有优异的抗拉强度和耐磨强度等物理性能
4、吸湿性：PVA的皮膜有较低的吸湿性，吸湿性随湿度的变化也比其他水溶性高分子小
5、耐药品耐油性：PVA具有很强的耐弱酸性和耐弱碱性，还有优异的耐油脂性
可乐丽PVA应用推荐：
长短纤维加工、纸张、粘结剂应用（纸用、再湿粘结、胶合板粘结、无机材料粘合），醋酸乙烯乳化剂、氯乙烯悬浮聚合、PVA薄膜、照相刻蚀、建材用添加剂、分散剂、挤出塑料加工、高阻隔包装材料
