defoamer for PU elastomers

Our defoamer for PU elastomers series is designed for manufacturers of molded elastomeric parts who require consistent surface quality and mechanical precision. This formulation prevents microbubbles during mixing, degassing, and casting, resulting in defect-free elastomer production. Used by OEM factories in wheels, rollers, gaskets, and coatings, it enhances appearance and dimensional stability. The defoamer remains stable under high shear, ensuring compatibility with both MDI and TDI systems. Its low-VOC composition supports sustainability and regulatory compliance. As a trusted additive partner, we deliver customized performance to elastomer producers worldwide seeking better flow, faster degassing, and consistent curing efficiency.

defoamer for PU elastomers

The defoamer for PU elastomers chemically disperses within the polyurethane matrix to collapse entrapped air and reduce surface tension during curing. It ensures uniform flow, stable viscosity, and smooth demolding in both hot-cast and cold-cure systems. Its silicone-modified formulation resists temperature fluctuation and prevents crater formation, ensuring clear, defect-free surfaces. Suitable for industrial elastomers like rollers, bushings, seals, and vibration dampers, it supports uniform polymerization and optimized curing kinetics without altering hardness or tensile properties.
