Socal® For enhanced impact performance in PVC

The Socal® range of ultra-fine precipitated calcium carbonate (PCC) grades has been specifically designed to improve fusion, gloss, impact strength and designing and shaping properties in PVC.

Socal® can be used as a nucleating agent, multifunctional filler, processing aid and impact modifier in PVC.


  • Socal® provides improved luminosity, a smooth finish and high gloss by improving melt elasticity and reinforcement
  • It improves impact resistance in rigid PVC, particularly at low temperatures, by reducing the temperature of transition between the tough and brittle states. It can be used to replace or supplement organic impact modifiers.
  • It speeds up fusion enabling compounders to achieve high extrusion rates while minimizing fouling of extruder screws and associated plate out
  • It is a highly effective flow aid limiting the compaction of problem powders and also provides control of viscosity without any adverse effect on adhesion
