【Introduction】
POEM Viscosity reducer is a kind of good non-ionic surfactant, with high wettability, dispersity and visocity reducing property. It is mainly used to produce and process PVC resin, to reduce the visciosity and improve the properties of EPVC. It is also widely sued as wetting agent, emulsifier and viscosity reducer in petroleum, detergent, pesticide, textile and such industries.

Application technique
POEM Viscosity reducer After the emulsion polymerization of EPVC has finished, add the viscosity reducer (0.1-1.0% of emulsion), stir it to uniform, and dry it to EPVC resin of low viscosity. Or add the viscosity reducer (0.5-2.0% of resin) according to the viscosity when producing EPVC.
POEM Viscosity reducer Please preheat it before use when the room temperature is lower than 10 ℃ to keep its high fluidity.
