Description

Crocidoliteasbestos CAS NO 12001-28-4 is a fibrous amphibole silicate mineral belonging to the asbestos group, specifically the riebeckite series. This material historically mattered for its exceptional tensile strength, flexibility, and resistance to heat, acids, and electricity. It was primarily needed by heavy industries for applications requiring durable, fire-resistant insulation and reinforcement. Due to its significant health hazards, its use is now heavily restricted or banned in most countries globally.

Application

Historically, crocidolite asbestos was utilized in various industrial sectors for its unique properties. Its primary applications included:

• Thermal and Acoustic Insulation: Sprayed coatings and lagging for pipes, boilers, and furnaces in industrial plants, ships, and power stations.
• Reinforcement Material: As a reinforcing fiber in asbestos-cement products such as pipes, sheets, and roofing materials.
• Friction Products: A key component in brake linings, clutch facings, and gaskets for automotive and machinery applications.
• Fireproofing and Protective Textiles: Woven into fire blankets, protective clothing, and theater safety curtains.
• High-Density Insulation Boards: Used in electrical switchgear and as a component in certain types of flooring.
• Filtering Medium: Employed in specialized chemical filtration processes due to its acid resistance.
• Laboratory and Research: Used in historical scientific studies and as a reference material in mineralogy and toxicology research.
