Silicones
Silicones are a versatile family of synthetic polymers composed of repeating units of siloxane (silicon-oxygen) bonds, often combined with carbon and hydrogen. These materials are renowned for their exceptional thermal stability, flexibility, water repellence, and biocompatibility, making them indispensable in various industries such as healthcare, automotive, electronics, construction, and personal care. At CymitQuimica, we offer a wide range of high-quality silicones, including fluids, elastomers, resins, and gels, each rigorously tested for purity and performance. Our silicone products are designed to meet the stringent demands of both research and industrial applications, providing excellent mechanical and chemical properties. By supplying top-tier silicones, we support researchers and industry professionals in developing innovative solutions and advanced materials, driving progress and efficiency in numerous technological and industrial fields.

CAS:DMS-R22: Methacryloxypropyl Terminated PDMS, 125-250 cSt (Telechelic Functional Fluid) Methacrylate and Acrylate functional siloxanes undergo the same reactions generally associated with methacrylates and acrylates, the most conspicuous being radical induced polymerization. Unlike vinylsiloxanes which are sluggish compared to their organic counterparts, methacrylate and acrylate siloxanes have similar reactivity to their organic counterparts. The principal applications of methacrylate functional siloxanes are as modifiers to organic systems. Upon radical induced polymerization, methacryloxypropyl terminated siloxanes by themselves only increase in viscosity. Copolymers with greater than 5 mole % methacrylate substitution crosslink to give non-flowable resins. Acrylate functional siloxanes cure greater than ten times as fast methacrylate functional siloxanes on exposure to UV in the presence of a photoinitiator such as ethylbenzoin. Oxygen is an inhibitor for methacrylate polymerization in general. The high oxygen permeability of siloxanes usually makes it necessary to blanket these materials with nitrogen or argon in order to obtain reasonable cures.
