Talc

Talc, also known as Hydrated Magnesium Silicate or (Soapstone) Mg₃Si₄O₁₀(OH)₂, is a naturally occurring mineral found in certain parts of the world. It is a soft, non-abrasive inert mineral powder that acts as a functional filler in paints, thermoplastics, rubber and adhesives. The flaky or plate-like structure of talc provides structural strength or reinforcement; heat resistance; pigmentation; opacity; rheology; and resistance in a variety of applications. Most commonly Talc is used in plastics such as polypropylene as a reinforcing filler. In addition to cosmetics and plastics, talc has several other applications, including as a lubricant in the production of ceramics, as a coating agent in the pharmaceutical industry, and as a filler in paints and coatings. In elastomers talc is commonly used in gaskets to reduce gas permeation.

Features and Benefits

Talc is a versatile mineral that has a wide range of applications in various industries, including coatings, rubber, personal care, and adhesives and sealants.

In coatings, talc is used as a filler and pigment to improve their performance and reduce cost formulations. It imparts whiteness, opacity, and brightness to coatings, and improves their mechanical and optical properties.

In rubber, talc is used to reduce gas permeability in seals and can be used as an anti-tack.

In personal care, it is used in cosmetics and pharmaceuticals as a lubricant, absorbent, and bulking agent.

In adhesives and sealants, talc is also used as a rheology modifier to improve the viscosity, thixotropy, and stability of the products.

Talc is widely used in the ceramics industry in both bodies and glazes.

In low-fire art-ware bodies, it imparts whiteness and increases thermal expansion to resist crazing.

In stoneware, small percentages of talc are used to flux the body and therefore improve strength and vitrification.

Talc is also used in the pharmaceutical industry due to its unique properties, including its ability to absorb moisture, lubricate, and flow easily.

Talc is a cost-effective option for manufacturers looking to improve product performance while reducing costs.

Industries

Coatings

Talc is used in coatings to improve their performance and reduce formulation costs. It imparts whiteness, opacity, and brightness and improves their mechanical and optical properties. It also creates a barrier effect, which limits the penetration of water and corrosive agents into paints and coatings, leading to a reduction in bubble formation, corrosion, and peeling. Used in many industrial coating types, especially primers, Talc can improve the precipitation of the paint, the mechanical force of the coating film, and the recoat ability.

Plastics

In the manufacture of polypropylene (PP), Talc is used as a filler to improve the mechanical properties of the polymer. Talc is a lamellar mineral that is compatible with PP and is characterised by its flexural strength, and modulus. Talc-filled PP grades offer higher stiffness, lower coefficient of thermal expansion, lower shrinkage, and improved scratch and impact resistance than non-filled grades.

Elastomers

Talc is used in elastomers to improve the acid, alkaline and heat resistance of the products. It is used as a reinforcing agent to improve the strength, stiffness, and dimensional stability of rubber products. It’s commonly used to reduce gas permeation in seals. It is also used in silicone rubber manufacturing as an anti-tack. Talc is smooth and slippery, making it useful as a lubricant and dusting agent for moulds, sheets of rubber, and any rubber product to prevent stickiness.
