Properties
and
application
The basic material for organic silicone industry.
Colorless,flammable,not soluble in water,easy to be hydrolyzed,dissolves in solvent such as benzene.It is used for the production of silicone fluids,silicone rubber etc.
It is an essential and capping agent in producing silicone fluid,also a good hydrophobic agent.Used in the treatment of textile surface and insulation,dampproof for radio parts etc.
Packing,
storage and
transportation
Plasitic barrels or iron barrels are applied for package.Prevent from damping and entering of acid-alkali impurities.The material is non-hazardous subsistence.
200L iron barrels with plastic coating are applied for package(190kg/barrel).Kept in cool and dry place,prevent from water and fire.Transportation as a hazardous subsistence.Storage period is one year.
Iron barrels with plastic lining are applied for package.Transportation as a hazardous subsistence.Kept in cool and dry place.Prevent from water,fire and sunlight.Storage period is 12months.
