hydride terminated polydimethylsiloxane, 2-3 cst - Introduction
It is a common organosilicon compound with the chemical formula (CH3)3SiO[(CH3)2SiO]nSi(CH3)3. It has some of the following properties:
1. Physical properties: It is a colorless and odorless liquid with low viscosity and high chemical stability.
2. Thermal stability: It can maintain its physical and chemical properties in a wide temperature range, from as low as -50 ° C to as high as 200 ° C.
3. Chemical stability: Excellent chemical stability in the presence of acid, alkali, solvent and oxygen.
4. Insulation performance: It has good electrical insulation and can be used for electrical insulation materials.
The main purpose of:
1. Lubricant: Due to its low viscosity and chemical stability, it is widely used in lubricants, sealants and greases.
2. Surfactant: It can be used to prepare special surfactants for skin care products, detergents and cosmetics.
3. Sealing material: It can be used in sealants and adhesives for electronic components, automotive parts and building materials.
preparation method: can be obtained by polymerizing dimethyl siloxane monomer under the action of a catalyst.
Safety information: It is a relatively safe compound, but care should be taken to prevent it from touching the skin and eyes. During use, follow proper operating procedures and use necessary protective measures, such as gloves and goggles. In case of contact with skin or eyes, rinse immediately with plenty of water and seek medical help.
