Description

Polydecene CAS NO 25189-70-2 is a synthetic hydrocarbon fluid belonging to the polyalphaolefin (PAO) family, specifically a decene oligomer. This high-performance material is valued for its exceptional thermal and oxidative stability, low volatility, and excellent lubricity. It is a critical base stock and functional fluid for demanding applications across the lubricants, personal care, and specialty chemicals industries, where consistent quality and reliable performance are paramount.

Application

• High-Performance Lubricants: Serves as a premium base stock for synthetic engine oils, gear oils, compressor oils, and greases, offering superior viscosity index and low-temperature fluidity.
• Personal Care & Cosmetics: Used as an emollient and skin-conditioning agent in creams, lotions, sunscreens, and color cosmetics due to its non-greasy feel and excellent spreadability.
• Industrial & Metalworking Fluids: Acts as a key component in formulating high-stability hydraulic fluids, heat transfer fluids, and metalworking coolants.
• Plastic & Rubber Processing: Functions as an internal lubricant and processing aid for polymers, improving mold release and surface finish.
• Adhesives & Sealants: Employed as a plasticizer and tackifier modifier to enhance flexibility and durability.
• Electrical & Electronic Fluids: Suitable for dielectric and cooling fluids in transformers and other electrical equipment.
