Applications of LS-624/V4 Tetravinyltetramethylcyclotetrasiloxane (V4) 2554-06-5

Mainly used for additives (intermediates) in the production process of high vinyl silicon oil, adding silicon rubber, liquid silicone, high ethylene silicon rubber, ethylene hydroxyl silicone oil, etc.
It is also one of the basic raw materials for synthesis of various silicon rubbers;
V4 and germ bromide quickly cross-coupling reactions. Under the participation of tetrafluorophone and catalysts, the coupled vinyl can be obtained under mild reaction conditions.
