Medical silicone oil is colorless and clear oily liquid; odorless or almost odorless, tasteless. Medical silicone oil is easily dissolved in chloroform, ether or toluene, but insoluble in water and ethanol. What are the uses of Wenzhou medical silicone oil?
Medical silicone oil is a kind of polyorganosiloxane with chain structure with different degree of polymerization. It is prepared by hydrolysis of dimethyldichlorosilane with water to obtain the primary polycondensated ring. The ring is cracked and rectified to obtain low ring. Then the ring body, capping agent and catalyst are put together to adjust and polymerize to obtain various mixtures with different polymerization degrees. The low boiling matter can be removed by vacuum distillation to obtain silicone oil.
Application: there are various viscosities. It has high heat resistance, water resistance, electrical insulation and small surface tension. Commonly used as high-grade lubricating oil, shockproof oil, insulating oil, defoamer, release agent, polishing agent and vacuum diffusion pump oil. Methyl silicone oil is more commonly used. In addition, there are ethyl silicone oil, methylphenyl silicone oil and nitrile containing silicone oil.
Medical silicone oil is a kind of polyorganosiloxane liquid and its derivatives, which are used to diagnose, prevent and treat diseases or play the role of lubrication and defoaming on medical devices. Broadly speaking, silicone oil used for skin care and beauty care also belongs to this category. The commonly used medical silicone oil is polydimethylsiloxane. By its defoaming property, it can be made into a swelling tablet for abdominal distension and an aerosol for treating pulmonary edema. It can also be used as an anti adhesion agent to prevent intestinal adhesion in abdominal surgery, as an antifoaming agent for gastric juice and a lubricant for some medical surgical instruments in gastroscopy.
