ALUMINUM SILICATE CAS 12141-46-7

Aluminium Silicate is a versatile inorganic compound occurring naturally in various clay minerals like kaolinite, or produced synthetically. It is widely valued across industries for its properties as a filler, extender, suspending agent, and reinforcing agent. Its high whiteness, chemical inertness, and thermal stability make it a preferred choice in applications ranging from paints and coatings to rubber and plastics. Depending on its specific mineralogical composition and processing, it can also function as an effective anti-caking agent.

Application:

Paints & Coatings: Acts as an extender pigment and filler, improving suspension, sheen control, and durability.

Plastics & Rubber: Serves as a functional filler and reinforcing agent, enhancing mechanical properties and heat resistance.

Ceramics: A key raw material in the production of ceramic bodies, glazes, and refractories due to its thermal properties.

Paper Industry: Used as a coating pigment and filler to improve paper smoothness, brightness, and printability.

Adhesives & Sealants: Functions as a thixotropic agent and filler, providing body and controlling flow.

Construction: Used in cement, gypsum products, and other building materials as a filler and to modify properties.

Personal Care: Found in cosmetics (e.g., powders, foundations) as a bulking agent, texture enhancer, and sometimes as an absorbent.

Safety profile:

Aluminium Silicate is generally considered to be a low-hazard, non-toxic material. It is chemically inert and non-irritating to the skin under normal conditions of handling. However, inhalation of fine dust particles should be avoided as prolonged exposure may cause respiratory irritation. Always use appropriate personal protective equipment (PPE) such as dust masks in dusty environments. It is not classified as a dangerous good according to GHS.

Storage requirements:

Store in a cool, dry, and well-ventilated area.
Keep bags tightly closed and sealed to prevent moisture absorption and contamination.
Keep away from strong acids and strong oxidizing agents.

Transport & Packaging:

Aluminium Silicate is typically supplied in:

20 kg or 25 multi-layer paper/plastic bags.

500 kg or 1000 kg jumbo bags (FIBCs).
Classified as non-hazardous for transport by land, sea, and air.
