Block Copolymer
Block copolymers are an extremely versatile range of non-ionic low-foaming surfactants of ethylene oxide and propylene oxide. The composition is a PO block flanked by polyethylene oxide chain, generating two primary functional hydroxyls.
The wide speared application of block copolymers is due in part to their low foam level and to their unusually low odor and toxicity. They are used as defoamer or antifreezing agent, in the formulation of dry-cleaning detergents.

We can produce other types of Block Copolymers (KEBPs), moreover customized packing will be available according to customer’s request.
Full information on the safety, handling and storage of KEBPs is available in the corresponding Material Safety Data Sheet (MSDS).
