Product description
Polydimethylsiloxane is a linear, nonreactive polydimethylsiloxane. Due to its chemical structure, Polydimethylsiloxane has an outstanding property profile, which sets it apart from organic materials such as mineral oils.
Properties
Polydimethylsiloxane is a clear, odorless and colorless liquid.
Special features
- minimal change in physical properties over a broad temperature range
- excellent water-repellent properties
- good dielectric properties
- low surface tension and thus high surface activity
- chemically highly unreactive
- low solidifying point
- high flash point
- high heat resistance
- good solubility in a wide range of solvents
Application
- release agent
- lubricant
- hydraulic fluid
- antifoam agent
- water-repellent agent
- liquid dielectric for electrical and electronic equipment
- heat-transfer oil
- polish additive
- plastics additive
- additive for textile and fiber auxiliaries
Processing
Due to Qunyue SILICONE FLUID's many diverse applications, no general processing information can be provided. Parameters will vary from application to
Application
Available in a range of viscosities,Qunyue SILICONE FLUIDS AK are miscible with each other in any ratio. The standard product's viscosity can thus be altered to suit your individual needs.
Polydimethylsiloxane is a non-polar liquid and is immiscible with polar solvents such as water or short-chain alcohols. In aliphatic and aromatic hydrocarbons, chlorohydrocarbons, ethers, esters, ketones and higher alcohols, Polydimethylsiloxane is soluble in any proportion.
Before the product is used with solvents for the first time, it is advisable to perform a lab-scale test.
When solvents are used, please remember to read the appropriate hazard information.
Storage
The 'Best use before end' date of each batch is shown on the product label.
Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
Maximum temperature allowed during storage and transportation: 50 °C
Safety notes
Comprehensive instructions are given in the corresponding Material Safety Data Sheets. They are available on request from Qunyue office.

Storage
Poly (methyl hydrosiloxane) has a shelf life of at least12 months when stored at 25 °C in the tightly closed original container. The 'Best use before end' date of each batch appears on the product label.
Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance Reasons.
Safety properties
Thermal stability
On heating for a short time in the absence of moisture,decomposition only occurs above 300 °C. In the presence of moisture, decomposition occurs at much lower temperatures together with the release of hydrogen, a viscosity increase and gelation, especially with thin films.
In the presence of certain catalysts H-siloxane may depolymerise with formation of volatile hydrogencontaining cyclic siloxanes.
Solubility, reactivity and hazards
Can be mixed with many organic solvents of low or average polarity. Can react with water, alcohols and proton active reagents of similar strength in the presence of suitable catalysts (acids, amines, metals,metallic salts) with hydrogen being released.
Particularly strong reactions can take place if only traces of alkalinematerial are present in a homogeneous mixture. Direct contact of H-siloxane with alkalis must be avoided, as well as the influence of strong oxidizing agents.
Ignition temperature
In our experience, the self-ignition temperature of H-siloxane is above 240 °C in the absence of reactive materials. Contact with porous or fibrous surfaces, eg, asbestos or asbestos substitutes, reduces the ignition temperature considerably. Foamy, resinous reaction products resulting from partial decomposition can also reduce the ignition temperature.
Safety precautions
In the event that H-siloxane splashes onto or is soaked up by the insulating material, the insulating material must be changed immediately. Please see our safety data sheet.
