This guide is written for compounders, technical managers and buyers at UK rubber manufacturers. It explains what rubber-grade talc is, what it does inside a compound, where it is used, which specifications to check on a data sheet, and how to choose a supplier you can rely on batch after batch.
Rubber talc is a finely ground, plate-shaped mineral filler that rubber manufacturers use for three jobs at once: as an anti-tack dusting agent, as a processing aid and as a semi-reinforcing filler. Used well, it stops uncured compound sticking together, gives smoother extrusions with cleaner edges, and lowers compound cost without a large drop in physical properties.
