Tetramethyl-clotetrasiloxane (D4H)

I.  Tetramethyl-clotetrasiloxane(D4H) RH-H102(D4H≥95%)Product Name: Tetramethyl-cyclotetrasiloxane(D4H)Main Composition： 1,3,5,7-tetrahydro-1,3,5,7-tetramethyl-clotetrasiloxaneFormula: C4H16O4Si4Molecular weight: 240.51CAS: 2370-88-9Character: Appearance: colourless transparent liquidPurity:>95%Visosity: 1-2csBoiling point: 135°CPerformance and Usage:Tetramethyl-clotetrasiloxane, is an active siloxane with Si-H bond,it can have the addition reaction with unsaturated alkene.Relative to linear Poly-methyl hydrogen polysiloxane, it has little impurity, high purity, fixed connect, easy to change the formula's designing, and can be used to manufacture methyl hydrogen siloxane and modification siloxane with defined hydrogen content and chain quantity. For example, it can be used to produce high molecular weight hydrogen silicone oil, vulcanization rubber in room temperature, addition style liquid silicone rubber cross linker, compound poly siloxane liquid crystal high molecularity, and other kinds of modification silicone oil, such as Hydroxy polysiloxane, Polyether silicone oil, Siloxane silicone oil, Hydroxy silicone oil, Amino silicone oil, etc.High purity of D4H also can be used as the  precursor of PCVD in Electricity industries,to form SiO2,SiC insulating film. Tetramethyl-clotetrasiloxane is also good impregnant of photolectric material.UN Number: UN 1993 3/PG 3HazardClass: 3Packing Group: IIIPackage: 1 ton IBC drum,  50kg, 25KG, 200KG barrel.Storage: Sealed and packed in cool and dried place, avoid from the contact with acid ,alkaline and fire.
