Description

Anthophyllitefibres CAS NO 77536-67-5 is a naturally occurring fibrous mineral belonging to the amphibole group of asbestos minerals. This material is valued in industrial applications for its high thermal stability, chemical resistance, and reinforcing properties. It is primarily utilized in specialized sectors such as high-temperature insulation, friction materials, and as a filler in composite materials where durability under stress is critical.

Application

• High-temperature insulation materials and gaskets
• Reinforcing filler in friction products like brake linings and clutch facings
• Component in specialty cement and composite materials
• Filter media and chemical-resistant packing
• Raw material in certain refractory and ceramic formulations
• Research and development in material science

Quality Control

Our Anthophyllitefibres are subject to stringent quality control protocols to ensure batch-to-batch consistency and compliance with relevant material safety and handling guidelines. Key parameters such as fiber morphology, chemical composition, and absence of extraneous minerals are verified. A Certificate of Analysis (COA) detailing specific lot characteristics is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area dedicated for mineral fibers. Maintain at room temperature (15-25°C) and control humidity to prevent caking. Ensure storage conditions comply with local and international regulations for handling asbestos minerals.
