Talc for Sheet Polymer Industries
Micro Talc TMC
(Talc for Rubber & Plastic) Grade TMC 54 & TMC 63
Micronized Talc Powder TMC is a natural mineral composed of magnesium oxide, magnesium carbonate, and hydrated magnesium silicate, with a fineness of up to 4000 mesh, and is widely used as a filler in the plastics, automotive rubber, tire, sponge rubber (EVA, footwear), and synthetic leather industries. This talc filler improves product stiffness, abrasion resistance, and impact strength, and is available in TMC 54 and TMC 63 grades, which differ in magnesium silicate content, density, whiteness, and physical properties. PT Niraku Jaya Abadi also offers custom-made talc powder specifications to meet specific customer requirements.
Talc
Powder
Talc powder is a hydrated magnesium silicate (3MgO·4SiO₂·3H₂O) whose composition may vary by mining source, and it has a layered, plate-like structure where weak Van der Waals forces allow the layers to slide easily under shear. As the softest mineral filler used in the plastics industry, talc offers high electrical resistivity, low gas permeability, low abrasiveness, and excellent lubricity, while its aspect ratio (up to 20:1) provides reinforcement benefits in polypropylene, high-density polyethylene, and other thermoplastics, especially when treated with coupling agents to improve polymer bonding.
Surface Treated
Micro Talc
Surface Treated Micro Talc UnicarbTMC-A is an enhanced version of Micro Talc TMC that has been specially treated with a functional additive coating to deliver improved overall performance. This surface modification helps strengthen the interaction and adhesion between talc filler particles and rubber or plastic resin, resulting in better mechanical properties such as higher tensile strength, improved impact resistance, and increased yield (elastic) strength. UnicarbTMC-A is available in TMC 54A and TMC 63A grades.
