Octamethylcyclotetrasiloxane(D4)

Name: D4,Octamethylcyclotetrasiloxane

Formula: [(CH3)2SiO]4

Standard: GB/T 20435-2006

Application: It’s a basic raw material of silicone oil (modified silicone oil),silicone emulsion,silicone rubber ,silicone resin and other silicone products, and can also be directly used as rubber filler treatment agents or raw material for cosmetics.

Precautions: The mixture of vapor and air is explosive. It’s easy to form explosive mixtures when fine dispersion composition in the air .Static electricity will be accumulated and may ignite vapors.
