Name: Dimethylsiloxane cyclics mixture
Formula: [(CH3)2SiO]n n=3,4,5,6,7
Implementation of standards: Q/ZTFG 002-2014
Chemical nature: Low Molecular Weight of cyclic siloxane would break the links, then forms the high linear polymer under the catalyst of acid or alkaline. In the process of polymer, polysiloxane of different molecular weights can be produced by controlling the ending agent and the relative concentration of cyclic.
Property＆Application: Dimethylcyclosiloxane(DMC) is the main raw material of producing silicone rubber and silicone oil. It is also wildly used in handling silicone rubber packing and cosmetics. The silicone rubber, silicone oil and other polysiloxane products which are made from DMC can be further processed into various modified silicone rubber and silicone oil with excellent high and low temperature resistance, aging resistance and insulating property.
Product standard: Dimethylcyclosiloxane(DMC)
