SOCAL® and WINNOFIL® are surface treated precipitated calcium carbonates specifically designed for use in rigid and liquid polymers, natural and synthetic elastomers.

In rigid PVC they function as cost effective processing aids and also provide valuable improvements in final mechanical properties. Surface finish and weatherability are also enhanced through their use. In flexible PVC cables, their inclusion can significantly limit acid gas release on combustion.

In natural and synthetic elastomers their use allows improvements in tear and tensile properties beyond that possible with standard extenders.

Because of their high specific surface area and controlled morphology, they act as effective nucleating agents in rigid foam systems and anti compaction additives for improving the handling of problem powders.

High whiteness and positive effect on rheology are of benefit in liquid resin systems.

Cables	Coated ultrafine precipitated calcium carbonate (CPCC) improves the processing behavior in rigid PVC and cables formulations.
Extrusion CPVC	PCC improves the surface finish and increases the impact strength in rigid CPVC.
Injection molding	PCC acts as a processing aid in PVC injection molding.
PVC Pipes	PCC acts as a processing aid in pressure pipe.
Rigid Foam	Coated precipitated calcium carbonate (CPCC) provides an unique combination of beneficial processing properties to the manufacture of rigid cellular PVC.
Window profiles	Coated precipitated calcium carbonate (CPCC) improves gelation and processing, surface finish and impact resistance in extrusion profile PVC compounds.
