Description

Hydrogenated Terphenyl CAS NO 3842-58-8 is a high-performance, partially or fully hydrogenated derivative of terphenyl, valued for its enhanced thermal stability and chemical resistance compared to its aromatic precursor. This modification makes it a superior choice for applications requiring a stable, high-boiling fluid or plasticizer under demanding conditions. It is a critical material for manufacturers in the polymer, electronics, and specialty chemical industries seeking reliable performance in heat transfer systems, high-temperature lubricants, and advanced composite materials.

Application

• As a high-temperature heat transfer fluid in closed-loop industrial systems.
• As a plasticizer and processing aid in the production of high-performance polymers and elastomers to improve flexibility and thermal stability.
• As a base fluid or additive in specialty lubricants and greases for extreme-temperature applications.
• As a dielectric fluid in specific electrical and electronic components.
• As a chemical intermediate for the synthesis of more complex specialty chemicals.
• As a component in high-temperature adhesives, sealants, and potting compounds.

Quality Control

Our Hydrogenated Terphenyl is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for hydrogenation degree, purity, and key physical properties. A comprehensive Certificate of Analysis (COA) documenting these results is provided to guarantee consistency and performance for your application.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from strong oxidizing agents. Due to its chemical nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) to minimize potential oxidation. Optimal storage temperature is between 15°C and 25°C.
