Polydimethylsiloxane in Chemicals
Product descriptionPolydimethylsiloxane 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.PropertiesPolydimethylsiloxane 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 solventsApplication- 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 auxiliariesStorageThe '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
