DECAMETHYLTETRASILOXANE Chemical Properties,Uses,Production
Chemical Properties
Colorless or yellowish transparent liquid
Uses
A non-cyclic silicone oligomer. Used in the methylation of mercury(II) salts. Study shows that it transformed by a specific microflora and in the natural environment degraded by mechanisms similar to other organic compounds.
Uses
Decamethyltetrasiloxane can be used as a basis for silicone oils or fluids designed to withstand extremes of temp; as a foam suppressant in petroleum lubricating oil.
Flammability and Explosibility
Flammable
Toxics Screening Level
The ITSL for decamethyltetrasiloxane has been changed from 0.04 μg/m3 to 0.1 μg/m3 based on an annual averaging time.
