High Boiling Silicone Oil: Guide
With the advancement of high boiling silicone oil production in China, product quality has become stable, leading to the establishment of the group standard “High-boiling Silicone Oil” (T/FSI 007-2017) for consistent quality control. This standard outlines the technical requirements, testing methods, inspection rules, and packaging, transportation, and storage guidelines for high-boiling silicone oil.
The high-boiling silicone oil, primarily made from methyl chlorosilane monomer distillation and processed via alcoholysis or hydrolysis, is composed of polymethylsiloxane mixtures. It features silicone-oxygen, silicone-carbon, and silicone-silicon bonds, with some branched chains. Ideal for applications such as defoamers, waterproofing agents, isolation agents, and more, high-boiling silicone oil meets various industry standards, with food and medical applications requiring additional testing.
