BIOF Supply Cosmetic Grade Polydimethylsiloxane Silicone Oil In Bulk CAS No. 31692-79-2

Polydimethylsiloxane (PDMS) is a silicone-based polymer that is widely used in various industrial and consumer applications due to its unique properties. 

Chemical Structure: PDMS is composed primarily of repeating units of dimethylsiloxane (-(CH3)2SiO-), which forms a flexible and stable polymer chain.

Physical Properties:

Flexibility: PDMS is highly flexible and has a low glass transition temperature, allowing it to remain pliable and elastic over a wide range of temperatures.
Inertness: It is chemically inert, meaning it is resistant to many chemicals, including water, acids, bases, and solvents.
Low Surface Tension: PDMS has a low surface tension, which gives it excellent spreading and wetting properties.

Applications:

Industrial Lubricants: PDMS is commonly used as a lubricant in various industries due to its low viscosity and high resistance to oxidation.
Antifoaming Agent: It is effective as an antifoaming agent in industrial processes such as food processing, wastewater treatment, and manufacturing.
Cosmetics and Personal Care: PDMS is used in skincare products, hair conditioners, and antiperspirants for its smooth, silky feel and water-repellent properties.
Medical and Healthcare: In medical applications, PDMS is used in surgical instruments, prosthetics, and medical tubing due to its biocompatibility and inertness.
Electronics: PDMS is used in electronics as a protective coating for electronics components and as a thermal interface material for heat dissipation.
Consumer Products: It is found in various household products like caulks, sealants, mold release agents, and as an ingredient in moldable silicone rubber products.
Safety and Environmental Considerations: PDMS is generally considered safe for use in consumer products and medical applications. It is biologically inert and does not accumulate in the environment. However, like any chemical, proper handling and disposal practices should be followed to minimize potential environmental impact.

Overall, polydimethylsiloxane (PDMS) is a versatile polymer with valuable properties that make it indispensable in a wide range of industrial, commercial, and consumer applications.
