概述
聚合物的表面活性取决于 EO/PO 比率。与普朗尼克 ® 表面活性剂相比，PPG-PEG-PPG 表现出较低的起泡性、较大的消泡性和较低的凝胶化倾向。PPG-PEG-PPG 的末端仲羟基与普朗尼克表面活性剂中的伯羟基相比，具有较低的反应活性和酸性。
应用
PPG-PEG-PPG 普朗尼克 ® 31R1 可作为表面清洗剂（软质和硬质）、涂料中的消泡剂、水处理中，金属加工中的润滑剂，线性和交联聚酯和聚氨酯的消泡剂和填充剂。 软硬表面清洁剂、涂料和水处理中的消泡剂。金属加工润滑剂，线性和交联聚酯及聚氨酯的消泡助剂和增量剂。
Surface activity of the polymer is dependent on the EO/PO ratio. PPG-PEG-PPG exhibits lower foaming, greater defoaming and reduced gelling tendencies relative to Pluronic ® surfactants. Terminal secondary hydroxyl groups of PPG-PEG-PPG have lower reactivity and acidity than the primary hydroxyl groups in Pluronic surfactants.
Application
Hard and soft surface cleaners, defoamers in coatings and water treatment. Lubricant in metal working, anti-foaming aid and extender for linear and cross-linked polyesters and polyurethanes. PPG-PEG-PPG Pluronic ® 31R1 can be used as surface cleaners (soft and hard), defoamers in coatings, in water treatment, lubricant in metal working, anti-foaming aid and extender for linear and cross-linked polyesters and polyurethanes.
