Talc powder, as an additive, modifier, or filler, is widely used in the papermaking industry, paint, architectural coatings, ceramics, chemical factories, daily chemicals, plastics, rubber, food products, and pharmaceuticals. Feldspar boasts advantages such as soft texture, low wear, high brightness, small absorption of blue light, and good transparency. Talc powder has four special skills: enhancement, heat insulation and preservation, insulation, nucleation, and anti-aging. This is why talc powder stands out among various fillers.

Industrial production manufacturing; in the papermaking industry, for instance, 10% to 20% of talc is commonly added to papermaking sizing, while in high-end double-sided copper paper, the addition of kaolin (or calcium bicarbonate) talc can reach up to 40%. Similarly, in plastic products, the addition of talc in modified materials can vary according to product specifications, reaching 30% to 50%. In some PVC products, the addition can be as high as 70%. Talc is extensively used in plastics, rubber, electronic devices, cables, paints, architectural coatings, wear-resistant materials, ceramics, decorative building materials, industrial, and electrical products.

Talcum powder is primarily produced through the processing of metal materials and mining enterprises' nitrogen compounds and their organic compounds. Talcum powder manufactured from metal materials or graphite ore includes iron powder, aluminum oxide powder, magnesium powder, titanium dioxide powder, manganese iron powder, copper shavings, lead powder, zinc powder, zinc oxide powder, molybdenum powder, tungsten powder, and more. Talcum powder produced from mining enterprises' nitrogen compounds includes kaolin powder, titanium dioxide powder, talcum powder, feldspar powder, calcite powder, slaked lime, heavy calcium powder, light calcium powder, fluorspar powder, quartz powder, barite powder, Flake graphite, jointing plaster, and bentonite powder. Ultra-fine talcum powder, whose raw materials are treated with modified materials, can significantly expand its application industries. Modified talcum powder, beyond being a filling material, serves as a key component in product formulation, enhancing and improving properties such as strength, ductility, wear resistance, resistance to high temperatures, aging resistance, and radiation protection, while also substantially reducing product costs. The article primarily discusses the use of talcum powder in the plastic industry.
