SILANOL TERMINATED POLYDIMETHYLSILOXANE (Cas 70131-67-8) Usage

Uses

Silanol terminated polydimethylsiloxane (PDMS) is a versatile silicone compound widely used in various industries. Its primary application lies in the production of silicone elastomers and sealants. PDMS provides excellent flexibility, durability, and resistance to high and low temperatures, making it an ideal choice for creating rubber-like materials used in gaskets, O-rings, and other sealing applications. Additionally, its low surface tension and good spreading properties make it a valuable ingredient in personal care products such as cosmetics, hair care products, and skin creams. PDMS is also used as a lubricant, releasing agent, and anti-foaming agent in various industrial processes. Its chemical stability and biocompatibility have further led to its utilization in medical and healthcare fields, including as a coating for medical devices and in the production of prosthetics. Overall, silanol terminated polydimethylsiloxane plays a crucial role in enabling the development of diverse products across multiple sectors.
