PI650标准和PI620标准将继续发挥重要作用，促进塑料瓶的回收和再利用。

除蜡脱脂异丙醇酰胺
除蜡水的配置过程中，最为关键的是，对表面活性剂的选择。

在过去的除蜡水生产过程中，常用6503,6501等表活剂，但是这些产品的综合性能远远不能达到现代日益更新的除蜡洗涤产品的要求，所以异丙醇酰胺6508，作为6501,6503，OP等产品的替代品，应运而生。

异丙醇酰胺，又名速蜡剂，稳泡剂，乳化剂，是除蜡水必须材料之一，在除蜡工业中，作蜡渍的洗涤剂，性能优异。

与油酸皂一起使用时，耐硬水性好，并广泛用于除油粉剂，脱脂粉、印刷油墨、绘图用品等产品。

同时可以用作其它洗涤剂的配料和增稠剂。

异丙醇酰胺，具有超强净洗、乳化、分散、柔软等性能，是体洗涤剂、除蜡水剂、清洗剂等各种洗涤产品不可缺少的原料，清洗能力远超OP,NP系列产品。

其对阴离子表面活性剂有较好的稳泡作用，属于非离子型，易溶于水，PH值为8.5-10.5（1%水溶液）。

异丙醇酰胺，为浅黄（深黄）色，粘稠液体。
