Parameters
Hydroxysilicone Oil
Properties: Hydroxy silicone oil is a linear polydimethylsiloxane with a hydroxyl end group, oily liquid. It has the characteristics of methyl silicone oil. Low viscosity hydroxyl silicone oil is an excellent structure control agent in silicone rubber processing, can replace diphenylsilanediol, simplify the process, improve the process productivity. In hydroxyl silicone oil, Si-O has high thermal stability; the Si-O-Si bond on the Si atom connected to the hydrocarbon group has the effect of dipole induction, which can improve its stability. The structure of the silicone oxygen chain also gives silicone low surface tension and weak intermolecular forces, and hydroxyl silicone oil, due to its special structure, has very good hydrophobicity. The viscosity can range from very small to tens of thousands of Pa-sec. Its hydroxyl content is from several ten thousandths to more than ten percent, typical hydroxyl silicone oil viscosity ≤ 40mPa - s (25 ℃), refractive index 1.4000 ~ 1.4100 (25 ℃), hydroxyl content 4% ~ 5%. The terminal hydroxyl group is reactive and can condense with hydroxyl or alkoxy compounds under the catalytic action of organotin.
