Dimethyl Silicone Oil Description

Dimethyl Silicone Oil (PDMS, CAS 63148-62-9) is a versatile, colorless, odorless, non-toxic, and non-volatile silicone oil commonly known as Dimethicone. As one of the earliest and most widely used silicone oils, it features a simple structure with exceptional properties. PDMS is the foundation for various silicone oils, with other formulations developed to enhance or modify its characteristics for specific applications.

Equivalent Product Name	201 Dimethicone; Foam stabilizer L10
Equivalent Chemical Name	Dimethicone; Polydimethylsiloxane; Dimethylsilicone fluid; Poly (dimethylsiloxane); Polydimethyl siloxane; Dimethicone
Physical Properties	Colorless transparent liquid
Chemical Properties	The linear Dimethyl Silicone Oil oil with Si-O-Si as the main chain and the methyl group connected to the silicon atom has a helical structure due to the small intermolecular force, and the methyl group is arranged outward and can rotate freely, so it has a Series features. Such as colorless and transparent, small temperature and viscosity coefficient, large expansion coefficient, low vapor pressure, high flash point, high and low temperature resistance, low surface tension, high compressibility, inert to materials, chemical inert, non-corrosive and physiological inert, positive It is these characteristics that determine its broad use.
Benefits	Ease of application and rubout Ease of buffing Enhances color High water repellency High compressibility High shearability without breakdown High spreadability and compatibility Low environmental hazard Low fire hazard Low reactivity and vapor pressure Low surface energy Good heat stability Essentially odorless, tasteless and nontoxic Soluble in a wide range of solvents
Uses	For personal care applications • Imparts soft, velvety skin feel • Spreads easily on both skin and hair • De-soaping (prevents foaming during rubout) For industrial applications • High dielectric strength • High damping action • Oxidation-, chemical- and weather-resistant Active ingredient in a variety of automotive, furniture, metal and specialty polishes in paste, emulsion and solvent-based polishes and aerosols Various applications including cosmetic ingredient, elastomer and plastics lubricant, electrical insulating fluid, foam preventive or breaker, mechanical fluid, mold release agent, surface active agent, and solvent-based finishing and fat liquoring of leather

Dimethyl Silicone Oil (PDMS): Guide

Dimethyl Silicone Oil (also known as Polydimethylsiloxane PDMS) is a non-toxic, hydrophobic silicone oil with exceptional properties like high/low temperature resistance, oxidation resistance, low viscosity-temperature coefficient, shear resistance, and low vapor pressure. As a versatile silicone oil, Dimethicone is widely used in various applications, including contact lenses, medical devices, elastomers, shampoos (for smooth and shiny hair), food (as a defoaming agent), caulks, lubricants, and heat-resistant tiles. Its unique rheological properties and electrical insulation make it indispensable across industries.
