Product Overview
We are offering our client an excellent quality range of Methyl Hydrogen Silicone Safety properties Thermal stability On heating for a short time in the absence of moisture,decomposition only occurs above 300 A C. In the presence of moisture, decomposition occurs at much lower temperatures together with the release of hydrogen, a viscosity increase and gelation, especially with thin films. In the presence of certain catalysts H-siloxane may depolymerise with formation of volatile hydrogencontaining cyclic siloxanes. Solubility, reactivity and hazards Can be mixed with many organic solvents of low or average polarity. Can react with water, alcohols and proton active reagents of similar strength in the presence of suitable catalysts (acids, amines, metals,metallic salts) with hydrogen being released. Particularly strong reactions can take place if only traces of alkalinematerial are present in a homogeneous mixture. Direct contact of H-siloxane with alkalis must be avoided, as well as the influence of strong oxidizing agents. Ignition temperature In our experience, the self-ignition temperature of H-siloxane is above 240 A C in the absence of reactive materials. Contact with porous or fibrous surfaces, eg, asbestos or asbestos substitutes, reduces the ignition temperature considerably. Foamy, resinous reaction products resulting from partial decomposition can also reduce the ignition temperature.
