SiVance MHD3.5MH (CAS No. 70900-21-9) is a hydride terminated silicone fluid.
MHD3.5MH is primarily used as a chain extender in addition cure silicone elastomers. The products is used in conjunction with crosslinking hydrides to increase elongation and tear strength and lower durometer. MHD3.5MH can also be used as a reactive intermediate to make ABA organo-modified silicones via hydrosilations. Functional groups normally attached in this way include allyl terminated polyethylene or polypropylene glycols, amines, and epoxies.
