Polyméthylhydrosiloxane

Description :

Polyméthylhydrosiloxane (PMHS), avec le numéro CAS 63148-57-2, est un polymère à base de silicone caractérisé par sa structure unique, qui comprend des groupes méthyle et hydrure attachés à des atomes de silicium. Ce composé est connu pour sa polyvalence et est couramment utilisé comme fluide ou résine silicone. PMHS présente une excellente stabilité thermique, une résistance chimique et une faible tension superficielle, ce qui le rend adapté à diverses applications, y compris les scellants, les adhésifs et les revêtements. Sa capacité de réaction d'hydrosilylation lui permet de participer à des processus de réticulation, améliorant les propriétés mécaniques des élastomères en silicone. De plus, le PMHS est souvent utilisé dans la formulation de produits de soin personnel en raison de ses propriétés conditionnantes pour la peau. Le polymère est généralement considéré comme sûr pour une utilisation dans les produits de consommation, mais des mesures de manipulation et de sécurité appropriées doivent être observées, comme pour toute substance chimique. Dans l'ensemble, le PMHS est apprécié pour ses propriétés fonctionnelles et son adaptabilité dans plusieurs secteurs, y compris l'automobile, l'électronique et les cosmétiques.

Poly(methylhydrosiloxane)

CAS : 63148-57-2

Poly(methylhydrosiloxane) is used in the reduction of esters to alcohols, catalyzed by a combination of titanocene dichloride and either n-BuLi or EtMgBr. It is a safer alternative to triethoxysilane, B22063, for reduction of phosphine oxides to phosphines, catalyzed by Ti(O-i-Pr)4. It is also used

Poly(methylhydrosiloxane)

CAS : 63148-57-2

Polymethylhydrosiloxane is a polymer that is used in coatings and adhesives. It has been shown to be an efficient aid for removing copper chloride from water and can be applied to the treatment of calcium carbonate sludge. Poly(methylhydrosiloxane) also has high affinity for fatty esters, which is important for its use as a mass analyzer in environmental pollution studies. This polymer has been shown to have excellent kinetic and optical properties, making it a good candidate for electrochemical studies.

CAS : 63148-57-2

Siloxane-Based Silane Reducing Agent
Organosilanes are hydrocarbon-like and possess the ability to serve as both ionic and free-radical reducing agents. These reagents and their reaction by-products are safer and more easily handled and disposed than many other reducing agents. The metallic nature of silicon and its low electronegativity relative to hydrogen lead to polarization of the Si-H bond yielding a hydridic hydrogen and a milder reducing agent compared to aluminum-, boron-, and other metal-based hydrides. A summary of some key silane reductions are presented in Table 1 of the Silicon-Based Reducing Agents brochure.
Pendant Functional Fluid; polyMethylHydrosiloxanes, TMS Terminated
