Description

Asbestos, Actinolite CAS NO 77536-66-4 is a fibrous silicate mineral belonging to the amphibole group of asbestos minerals. This material is of significant industrial and research interest due to its unique physical properties, including high tensile strength and resistance to heat, chemicals, and electricity. It is primarily sought by industries and research institutions involved in materials science, historical product analysis, and controlled environmental studies. Our supply ensures a consistent and reliably characterized source for these specialized applications.

Application

• Reference Standard for Analysis: Used as a certified reference material in laboratories for the qualitative and quantitative identification of amphibole asbestos fibers in environmental, industrial hygiene, and bulk material samples.
• Materials Science Research: Serves as a model compound in academic and industrial research studying the properties, durability, and safe handling protocols of silicate minerals and fibrous materials.
• Forensic and Historical Investigation: Employed in the analysis of older construction materials, products, and sites to determine the presence and type of asbestos for regulatory and remediation purposes.
• Quality Control in Specialized Manufacturing: Acts as a known standard in the quality assurance processes for industries that manufacture asbestos-free alternative materials, ensuring their products meet stringent compositional criteria.
• Regulatory Compliance Testing: Essential for calibrating analytical equipment and validating test methods required by occupational health and environmental protection agencies worldwide.
