In plastics and rubber manufacturing, talc acts as a filler to enhance product performance. It increases stiffness, heat resistance, and dimensional stability, making plastic parts more durable and easier to process. Talc also lowers production costs by replacing some polymer resin. In rubber, talc improves processing by reducing stickiness, enhancing flow, and improving surface finish. Its layered structure and chemical inertness make talc ideal for boosting mechanical and thermal properties while maintaining chemical resistance.
