Description

Arochlor 1232 is a specific polychlorinated biphenyl (PCB) mixture, identified by the CAS registry number 37324-23-5. This product is valued for its historical use as a stable dielectric fluid and heat transfer agent in closed industrial systems. It is primarily required by specialized sectors for research, analytical reference standards, and legacy equipment maintenance where specific PCB congeners are necessary.

Application

• Primary use as a dielectric insulating fluid in transformers and capacitors (historical/legacy systems).
• Employed as a heat transfer fluid in closed-loop industrial heating systems.
• Serves as a critical reference standard and calibrant in environmental testing laboratories for PCB analysis.
• Used in scientific research to study the environmental fate, toxicology, and remediation of PCBs.
• Application as a plasticizer and additive in specific elastomers and adhesives (historical use).
• Component in specialty hydraulic fluids and lubricants for extreme pressure conditions.
