General description
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.
Features and Benefits
Surface activity is dependent on the EO/PO ratio. Lower foaming, greater defoaming and reduced gelling tendencies relative to Pluronic® surfactants. Terminal secondary hydroxyl groups have lower reactivity and acidity than the primary hydroxyl groups in Pluronic® surfactants.

The block polyethers PEO-PPO-ph-PPO-PEO (BPE) and PPO-PEO-ph-PEO-PPO (BEP) are synthesized by anionic polymerization using bisphenol A as initiator. Compared with Pluronic P123, the aggregation behaviors of BPE and BEP at an air/water interface are investigated by the surface tension and
