Applications

Modified Plastics

Talc, particularly in its pure and platy forms, is widely used in plastic systems due to its high aspect ratio, a key property for improving the performance of thermoplastics, especially polypropylene. Beyond that, it’s also suitable for polyethylene and polyamide-based products. Its inclusion helps strengthen plastic components, making it an ideal choice for parts like bumpers, dashboards, and various automotive parts. Talc is also found in door panels, tailgates, side shields, underbody shields, air conditioning casings, and household appliances, where durability and stability are critical.

Recommended products: SK-7800, SK-8100A, SK-102Q, NA-7800, SK-98

Rubber

In the rubber industry, talc serves multiple functions, acting as a filler, insulator, and reinforcing agent. It helps improve vulcanization, enhances elasticity, and increases tensile strength, making it an essential component in various rubber formulations. Talc is commonly used in natural rubber, nitrile rubber (NBR), and EPDM rubber, among others. Its insulating properties also make it ideal for use in electrical cables and other rubber-based applications where durability and flexibility are critical.

Recommended products: RB-1063

EVA Foam (Shoe Materials)

Used as a filler in the production of EVA foam for shoe materials, talc not only helps reduce production costs but also ensures good melt flow, improves molding speed, and lowers energy consumption. Additionally, it enhances the final product’s tensile strength, abrasion resistance, crack resistance, and impact strength. Our talc products are widely used by major global sports shoe brands, ensuring quality and durability in every pair.

Recommended products: RB-510

Paints & Coatings

Talc is commonly used as a filler in paints, providing structural support and improving the hardness of the paint film. It enhances the stability of the coating, increases tensile, shear, and flexural strength, and reduces deformation and thermal expansion. Additionally, talc helps lower production costs, making it an ideal choice for architectural, industrial, wood, anti-corrosion, and waterproof coatings, as well as other conventional paints.

Recommended products:

Inks: SK-7800
Paints: SK-480B, NA-1250
Anti-corrosion Paints: NA-7800

Honeycomb Ceramic

Widely used in the ceramics industry, talc plays a key role in the production of honeycomb ceramics. Its specific properties enhance the strength and performance of these unique ceramic materials.

Recommended products: TC Series

Paper

As a filler widely used in the paper industry, talc enhances the smoothness and durability of paper, while also increasing its weight. Its ability to boost ink absorption makes it ideal for improving print quality. Additionally, talc is often used as a substitute for kaolin in paper coatings, providing a reliable option for high-performance printing applications.

Recommended products: SK-350, SK-5100
