FAQs
What is talc?
Talc is a naturally occurring non-metallic mineral, also known as hydrated magnesium silicate, with the chemical formula 3MgO·4SiO₂·H₂O. It is the softest mineral found in nature.
Talc is a magnesium-rich mineral with a layered, sheet-like structure, while calcium carbonate is a calcium compound with a granular structure. Talc features softness and layered properties that make it ideal for a range of applications, including cosmetics, plastics, and coatings, as it enhances durability and acid resistance. Calcium carbonate, though commonly used as a filler, lacks the acid resistance talc provides
Talc is commonly used as an additive during the manufacturing of various automotive parts such as bumpers, dashboards, seat bases, carpets, and interior trim to enhance durability, strength, and heat resistance
Yes, talc is an important additive used during the production of plastics used in air conditioner casings and other home appliances. It improves the mechanical properties of the plastic by enhancing rigidity, heat resistance, and dimensional stability, making the end products more durable and suitable for high-performance applications
Talc improves the smoothness, scratch resistance, fire resistance, and anti-corrosion properties of coatings. It also helps increase the hardness of the film, enhancing shear and tensile strength, while reducing production costs
Talc used in honeycomb ceramics has high purity, a well-defined plate-like structure, low levels of interfering ions, and a uniform particle size distribution
Talc enhances hardness, improves heat resistance and wearability, reduces the stickiness of rubber products, and helps regulate their resistance to cracking
