Performance and technical indexes
Appearance and properties: Colorless, transparent liquid without mechanic impurity.
pH Value: - Melting Point(C): -76.1
Relative Density(Water's=1): 1.07 Boiling Point(C): 70.2
Relative Density(Air's=1): 4.45 Octanol/water distribution coefficient: -
Ignation Temperature(C): 3802
Upper Limit of Explosion[%(V/V)]: 10.4 Lower Limit of Explosion [%(V/V)]: 5.5
Dissolubility: Soluble in benzene, aether etc.

Applications: It is the basic material of silicone. It is mainly used in the production of intermediates of silicone(D4, DMC), silicone oil, silicone rubber, silicon resin etc. And it is also used in the production of anti-heat and high intensity carbonized fibre.

Hazard characteristics: Inflammation and explosion will arise when it meets naked fire, high heat or oxidandt. And it will decompose with exothermic heat and poisonous caustic smoke when it is heated or encounters water. Interior pressure increase shall lead to the danger of splitting and explosion when it meets high heat. It is of causticity.
Stability: Stable, strong reaction with water and alcohol, combustible.
Polymerized danger: Free of polymerization
Access prohibition: Humid air
Banned articles: Strong alkali, Water, Strong acid
Combustion(decomposition) products: Carbon oxide, carbon dioxide, monox, hydride chlorine, phosgene
Package storage and transportation: It should be packed in 200L iron drum(net weight 200kg/drum) and be stored in a shady, cool and ventilated storehouse. It should be keep away from kindling; Temperatue in the storehouse above 30C is not suitable. Avoid direct sunlight. Air-proof package is required without contact with air. And it should be placed and stored far away from oxidant, acid and alkali. The installation of lighting and ventilation in the storehouse should be explosion-proof. Swithes must be located outside the house. Corresponding varied and quantitative fire fighting equipment should be equiped. Check regularly to make sure free of leakage. Operate and handle in nitrogen gas. When conveyig, take care of loading and unloading to avoid damages on package and vessels. A regulated route is required for transportation without changing the route or halting suddenly.

Quality gurantee period: Quality guarantee period for this product is 6 months. Recheck by this standard is required when the product exceeds the time limits. The product can be used only after the test result is qualified.
