Description

Aroclor CAS NO 12767-79-2 is a commercial mixture of polychlorinated biphenyls (PCBs) historically used for their exceptional thermal stability and electrical insulating properties. This product is supplied for specialized industrial and research applications where these inert, non-flammable characteristics are required. It is relevant for sectors such as historical equipment maintenance, material science research, and controlled chemical synthesis.

Application

• Historical Electrical Equipment: As a dielectric fluid in capacitors and transformers.
• Research & Development: As a reference standard or model compound in environmental, toxicological, and analytical chemistry studies.
• Industrial Additive: As a plasticizer, flame retardant, or additive in adhesives, sealants, and specialized coatings (for legacy or exempted uses).
• Chemical Intermediate: For controlled synthesis in laboratory settings to produce derivatives for research purposes.
• Material Testing: Used as a challenging contaminant in the development and validation of remediation and detection technologies.
