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.

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

- 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

Due to Qunyue SILICONE FLUID's many diverse applications, no general processing information can be provided. Parameters will vary from application to

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.

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.
