Polydimethylsiloxane PDMS

Chemical Name: Polydimethylsiloxane (PDMS)

CAS No: 63148-62-9

Our offer includes the silicon-organic polymers produced in a wide range of viscosity from: 5 to 5 million cSt.

Low Viscosity Silicone fluid at viscosity 5cSt,10cSt,20cSt

Standard Viscosity Silicone fluid at 5.000cst, 10.000cst, 12.500cst,30.000cst,60.000cst,100.000cst

High Viscosity Silicone fluid at 300.000cst,600.000cst,1,000,000cst,2.500.000cst,20.000.000cst ect.

These fluids are characterized by the following special properties:

● Heat and cold resistant, can work between -50℃~+200℃ in the long run.

● Viscosity ranging from 5-5 million cs, also insignificant temperature dependence of viscosity.

● Excellent insulation performance, good water repellent and moisture resistant.

● Good chemical stability,high resistance to weathering and oxidation conditions.

● Inert, odorless, tasteless, stainless, and therefore ideal for medical and food applications.

● Low surface tension, high flash point, low freezing point.

Usage

1. Antifoam, the widest antifoam agent, heat-resistant, safe, non-toxic, widely used in petroleum, chemical, printing and dyeing, painting, leather, pharmacy and food industry

2.Lubricant, polydimethylsiloxane has excellent lubrication.

3.Mold release agent, used alone or as part of a compounded formula, polydimethylsiloxane  provides a non-carbonizing nould release for rubber, plastics, and metal die castings.

4. Cosmetics and Skin preparation, polydimethylsiloxane is an important ingredient in hand creams, skin protectants, suntan lotions, and hair grooming aids because it forms a non-greasy, protective film which resists water and waterborne irritants, yet allows the skin to breathe.

5.Surface active material, add small volume of this product in the paint, rubber, resin and paraffin can obviously improve the flow characteristics and lubricates the surface of the completed part.

6.Polish and Chemical Specialties, polydimethylsiloxane is used in most automobile and furniture polishes for its ease of application,high gloss with minimum rubbing, and a durable water-repellent film. It is also used in many other specialty formulations, including aerosol starches and fabric conditioners.

7. Softener, hydrophobic agent, feel improving agent, sewing line lubrication, chemical fiber spinneret lubrication and clothing pressure lining auxiliaries, etc.

8. Electrical & Electric equipment. With excellent dielectric properties, polydimethylsiloxane can be used for both insulating and damping applications.

9. Mechanical Fluid. Excellent viscosity-temperature characteristics, thermal and chemical stability, shear-breakdown resistance, compressibility, and rubber compatibility make polydimethylsiloxane outstanding for mechanical/ hydraulic uses. Typical uses include hydraulic stabilizers, damping media.
