Processing & partitioning aid Imerys Carbonates – an effective processing and partitioning agent
Imerys Carbonates improve processability while maintaining mechanical properties and lowering compound costs. They are ideal for use as anti-tack agents.
Imerys surface treated carbonate facilitates slippage between the rubber sheet layers at solid surfaces making it an excellent partitioning agent, and functions as an internal lubricant.
Used in addition to or as a partial replacement for carbon black, Imerys Carbonate such as our Imerseal ™ grade reduces Mooney viscosity by up to 40% and improves mold flow and scorch without affecting cure rate. This combination of improved viscosity and scorch safety widens the processing window.
The surface treated carbonate is inherently spherical and slippery, meaning it acts as an external lubricant. Imerys Carbonate is an excellent anti-sticking agent in compound handling, processing and part manufacturing.
We offer a full range of custom formulation and technical and process support services to help you match the right mineral grade to your application requirement.
