Polydimethylsiloxane (PDMS)

详情

Polydimethylsiloxane ( PDMS) :

(1). Features:
- WM***1 Two dimethyl silicone oil, chemical name is Polydimethylsiloxane, which formula is (CH3)3SiO[(CH3)2SiO]n-Si(CH3)3, this products is a kind of transparent, colourless polydimethylsilixane liquid, available viscosities ranging from *5cps to ******0cps.
- Little change in physical properties over a wide temperature span - arelatively flat viscosity-temperature slope, and serviceability from **0° C up to **0° C.
- Excellent water repellency.
- Good dielectic properties over a wide range of temperatures and frequencies.
- Low surface tension - readily wets clean surfaces to impart water repellency and release characteristics.
- Viscosities above *0 mm² /s also exhibit heat stability, oxidation resistance, very low vapour pressures, and high flash point.
- Low order of toxicity
- Essentially odourless
- Soluble in a wide range of solvent
- Non-greasy and non-rancidifying

(2). Application:
RELEASE MATERIAL: Used alone or as part of a compounded formula,
WM***1 Fluid provides a non-carbonising mould release for rubber, plastics, and metal die castings.
FOAM PREVENTITIVE: Extremely small amounts of the fluid effectively control foam in many processing operations, especially in non-aqueous systems.
MECHANICALFLUID: Excellent viscosity-temperature characteristics,
Thermal and chemical stability, shear-breakdown resistance, compressibility, and rubber compatibility make WM***1 Fluid outstanding for mechanical/ hydraulic uses. Typical uses include hydrolic stabilisers, damping media.

SURFACE-ACTIVE MATERIAL: Added to vinyl plastisols,

WM***1 Fluid improves the flow characteristics, de-aerates and
Lubricates the surface of the completed part.
LUBRICANT: The fluid provides excellent lubrication for most plastic and elastomeric surfaces. Lubricity with metals depends upon the combination involved. Care should be taken to select suitable metals for pumps and other items with moving parts.
COSMETICS AND SKIN PREPARATIONS: WM***1 Fluid 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. Literature is available that details the use of the fluid in cosmetics.
POLISHES AND CHEMICAL SPECIALITIES: WM***1 Fluid is used in most automobile and furniture polishes for its ease of application, high gloss with minimum rubbing, and a durable water-repellant film. It is also used in many other speciality formulations, including aerosol starches and fabric conditioners. Additional literature is available.
ELECTRICAL/ELECTRONIC EQUIPMENT: With excellent dielectric
Properties, WM***1 Fluid can be used for both insulating and damping applications.
