Application characteristics of talc powder

Release date: 2024-02-19

The application characteristics of talc powder are mainly reflected in: reinforcement, heat preservation, barrier, nucleation, and aging resistance. This is why talc powder can stand out among many fillers. Talc has the advantages of soft texture, low abrasion, high gloss, low oil absorption value, and good transparency.

Application characteristics of talc powder

1. Enhancement

The significant reinforcing effect of talc on plastic products mainly comes from its unique microscopic flake structure. The more complete the flake structure of processed talc powder is, the more obvious its reinforcing effect will be. A larger diameter-to-thickness ratio (the ratio of the average diameter of flake particles to its thickness) can improve the rigidity, impact strength, flexural modulus and thermal stability of plastic products. Such as bumpers, car interior parts, etc.

2. Insulation and isolation

High-quality ultra-fine talc powder has a flaky structure. When used in plastic products, it can be evenly dispersed in the resin in a layered manner. Just like the metal structural mesh embedded in cement products, it can not only maintain the advantages of plastics, but also form an enhanced support form with excellent mechanical properties. It can improve the physical properties of plastic products and also has obvious thermal insulation and barrier effects.

3. Nucleation

The slipperiness of talc is very obvious, and the opening of plastics added with talc powder is significantly improved, and the anti-adhesion properties of the film can also be improved. When ultrafine talc powder (below 1 μm) is evenly dispersed in the plastic matrix, it can act as a nucleating agent, such as in PET plastics.

4. Aging resistance

Talc, mica, kaolin and other silicon-containing minerals have infrared and ultraviolet barrier properties, and have obvious thermal insulation and aging resistance effects in plastic products.
