Application:

Octaphenylcyclotetrasiloxane (CAS: 546-56-5) can be used for synthesizing pharmaceutical intermediates and organic silicone intermediates, especially for high temperature resistant phenyl silicone oil and other polymers. Used for the preparation of phenyl silicone rubber. Can be used in antifouling coatings to reduce the surface energy of coatings, increase the flexibility of film and decrease bubbles in the process. Can be used with vinyl silicone oil for the synthesis of phenyl vinyl silicone oil. It can increase the viscosity, refractive index and heat stability of the finished product. Such phenyl vinyl silicone oil is mainly applied in LED encapsulation. Can be used as a raw material for the synthesis of organic silicone products and pharmaceutical intermediates. Can also be used to produce phenyl silicone rubbers and other organic silicone materials. Octaphenylcyclotetrasiloxane is a useful research chemical mostly used in the preparation of larger macromolecules. Examples of Octaphenylcyclotetrasiloxane-based compounds include nanoporous polymers with narrow pore-size distribution for cell imaging and explosive detection, addition-curable type liquid silicone rubbers, and CO2 adsorbing microporous polymers.
