Description

Silicone Oil CAS NO 63148-62-9 is a versatile organosilicon polymer, primarily polydimethylsiloxane (PDMS), valued for its exceptional thermal stability, low surface tension, and wide-ranging chemical inertness. This combination of properties makes it an indispensable performance additive and base fluid across numerous high-tech and industrial sectors. Key industries that rely on this material include personal care and cosmetics, pharmaceuticals, textiles, plastics, and release agents for manufacturing.

Application

• Personal Care & Cosmetics: Acts as an emollient and conditioning agent in hair care products, skin creams, and antiperspirants, providing a smooth, non-greasy feel.
• Pharmaceuticals & Medical: Used as a lubricant for syringe plungers and stoppers, in topical ointments, and as an anti-foaming agent.
• Industrial Lubricants & Release Agents: Serves as a high-temperature lubricant for bearings and gears, and as a mold release agent in rubber, plastic, and composite manufacturing.
• Textile & Fiber Treatment: Imparts water repellency, softness, and lubricity to fibers and fabrics during processing.
• Polishes & Coatings: A key ingredient in automotive and furniture polishes, providing shine and protection.
• Defoamers & Antifoams: Widely used in aqueous and non-aqueous systems to control foam in processes like fermentation, wastewater treatment, and chemical manufacturing.
• Electrical & Electronics: Employed as a dielectric coolant and heat transfer fluid in transformers and other electrical equipment.
• Plastics & Rubber: Functions as an internal lubricant and processing aid to improve flow and mold release.
