Application

Poly(dimethylsiloxane), with an average molecular weight of 115,000, is a versatile silicone compound widely recognized for its unique chemical properties and extensive industrial applications. This colorless liquid features a distinct viscosity and can be produced in various forms such as gels, fluids, resins, or elastomers, depending on its cross-linking traits. Its primary purpose lies in acting as an antifoaming agent in both food and industrial processes, effectively preventing foaming and spattering in heated oils and during the production of items like wine, refined sugar, gelatin, and chewing gum. Furthermore, it is utilized in the medical field, particularly in simethicone mixtures, where it is combined with silica gel to form a substance that reduces bloating by lowering surface tension in gas bubbles. This characteristic makes it beneficial in easing gastrointestinal discomfort and aiding ultrasound examinations by minimizing excessive gas in the stomach or intestines. Overall, poly(dimethylsiloxane) is a crucial component in numerous applications, valued for its safety and functional benefits.
