General Manufacturing InformationCyclopentane, (trichlorosilyl)-: ACTIVE

Applications

UsesTrichloro(cyclopentyl)silane can be used in the preparation of POSS by hydrolysis and condensation reaction that is majorly used to enhance the thermo-mechanical properties of different polymers.

General DescriptionTrichloro(cyclopentyl)silane is a polyhedral oligomeric silsesquioxane (POSS) derivate which is synthesized by hydrosilylation of cyclopentene and trichlorosilane.
