Pluskim – SAN-Filled Polyester Polyol Production

In polyurethane systems, polyester polyols play a crucial role in determining foam properties. One of the most effective ways to enhance these polyols is by incorporating SAN (Styrene Acrylonitrile) fillers. Pluskim manufactures SAN-filled polyester polyols to improve mechanical strength, cell stability, and viscosity control —all without compromising reactivity.

Benefits of SAN in Polyester Polyols

Finely dispersed SAN particles in the polyol matrix:

Increase mechanical strength (tensile, hardness)
Improve foam cell stability
Reduce shrinkage and collapse risks
Enhance surface quality
Maintain reactivity while offering viscosity control

These characteristics are ideal for high-resilience and structure-demanding foam applications.
