Mineral fillers are a quiet but important part of plastics and rubber. Used well, they cut material cost and improve stiffness and finish. Used inconsistently, they upset melt flow, cause surface defects and slow the line down.
For PVC pipes, profiles and fittings, our customers mainly use calcite powder and finer GCC powder, chosen by mesh size and brightness. Masterbatch producers prefer high-brightness, fine grades for white and light shades, and titanium dioxide where opacity is needed.
Rubber compounding
In rubber, china clay is a semi-reinforcing filler that improves stiffness and tear resistance at low cost, while calcite works as a general extender. Soapstone (talc) is often used as a dusting and anti-tack agent.
