Product Description
Dimethyl silicone oil also known as dimethicone,the CAS number is 63148-62-9 and the molecular formula is C6H18OSi₂. It is a polyorganosiloxane with a chain structure of different degrees of polymerization. It is produced by hydrolyzing dimethyldichlorosilane with water to obtain a primary polycondensation ring body. The ring body is cracked and distilled to obtain a lower ring body. Then the ring body, head-capping agent and catalyst are put together and polymerized to obtain each Silicone oil can be obtained by distilling a mixture of different degrees of polymerization under reduced pressure to remove low boiling matter.
Product Feature
1.It has excellent heat resistance, electrical insulation, weather resistance, hydrophobicity, physiological inertness and small surface tension. In addition, it also has a low viscosity-temperature coefficient and high compression resistance. Some varieties are also radiation-resistant. performance.
2.It is a non-toxic oil with low foaming and strong anti-foaming properties. It can be used as a defoaming agent.
3.The viscosity-temperature performance is the best among liquid lubricants, and the viscosity changes little over a wide temperature range. The appearance and viscosity of the oil will not change after long-term storage at low temperatures. It is a base oil that can take into account high temperature, low temperature and wide temperature range.
4.Commonly used as high-grade lubricating oil, anti-vibration oil, insulating oil, defoaming agent, release agent, polishing agent and vacuum diffusion pump oil, etc.
