English description（英文原文，共 1625 字符）
Product Name:Polymethylsilane
English Name:Polymethylsilane
CAS No.:105064-43-5
Aliases:PMS
Molecular Formula:(CH4Si)n
Physical Properties:Colorless to light yellow transparent liquid or low-melting-point solid with a pungent odor. Soluble in organic solvents such as toluene, benzene and n-hexane; insoluble in water. It exhibits high chemical reactivity, with Si-H bonds prone to dehydrogenative coupling and cross-linking reactions, and can be cured to form a ceramic precursor upon heating.
Uses:Used as a raw material for ceramization of carbon/carbon composites to improve their oxidation resistance and mechanical properties, especially for ceramization of aerospace thermal protection/structural materials and components, comparable to polycarbosilane (PCS). Used as a raw material for soft-phase silicon carbide in carbon-ceramic brake discs/pads to reduce judder and wear during friction, suitable for braking systems requiring high quality, braking performance, safety and service life. Used as a binder for graphite or silicon carbide powders to prepare graphite ceramic products, high-purity silicon carbide materials and porous silicon carbide ceramics. Also used as a reinforcing resin for silicon carbide coatings to prepare high-temperature protective coatings for non-metallic materials.
Technical Specifications:
Appearance: colorless to light yellow transparent liquid or low-melting-point solid.
Density (25°C): 0.90~1.00 g/cm³.
Viscosity (25°C): 20~80 mPa·s.
Ceramic yield at 1000°C in nitrogen: not less than 50%.
Soluble in toluene, n-hexane and other organic solvents; insoluble in water.
