Introduction: Hexamethyldisiloxane (silicone ether, MM sealing agent) is a colorless and transparent liquid that is prone to deliquescence. Insoluble in water, soluble in various organic solvents. Used as silicone oil, silicone rubber, pharmaceuticals, gas chromatography stationary liquids, analytical reagents, hydrophobic agents, etc. Obtained by hydrolysis of trimethylchlorosilane. The physical properties of hexamethyldisiloxane colorless and transparent liquids. Easily deliquescent, flammable, and in contact with high heat, open flames, and strong oxidizing agents, there is a risk of combustion. Boiling point 99.5 ℃. Flash point -1.1 ℃. Relative density (d2525) 0.7606. The refractive index is 1.3750. Insoluble in water, soluble in various organic solvents. Hexamethyldisiloxane is an important primary organic silicon raw material, often used as a capping agent in the production of silicone oil, or as a cleaning agent for silicone rubber, pharmaceuticals, gas c...

Methyl Vinyl Silicone Rubber CAS NO.67762-94-1
Name:Methyl Vinyl Silicone Rubber
CAS No.:67762-94-1
Appearance: colorless transparent
Molecular formula: RMe2SiO(Me2SiO)n(MeViSiO)mSiMe2R(R：Me、Vi)
Relative density (water=1): 0.97
Boiling point: 205℃
Performance and use:
This product is insoluble in water, soluble in toluene, etc. It has the excellent characteristics of small compression deformation and resistance to saturated vapor pressure. In aviation, electronics, machinery, chemical and other industrial sectors, it can be used to manufacture high and low temperature resistant sealing materials and waterproof and moisture-proof insulating materials. And because of its physiological inertness, it can be used to produce artificial organs and medical tubes, and raw materials for high-temperature kneading silicone rubber.
Packaging and Storage:
Packed in a carton box lined with plastic bags, 25kg/carton. It should be stored in a cool, dry, well-ventilated place, away from strong oxidants. Avoid contact with strong acid, strong alkali and metallic lead. Transport as non-dangerous goods. Light loading and unloading during handling to prevent package damage. When transporting, it should be rain-proof, moisture-proof, sun-proof, and prevent the infiltration of impurities such as acid and alkali.
