How to produce Polydemthylsiloxane PDSM( dimethyl silicone oil)

The method of our factory is to use Octamethylcyclotetrasiloxane D4 and Hexamethyldisiloxane MM as the main raw materials,  and  use D001 large pore cation (H) exchange resin as catalyst. This method is to monitor the equilibrium state of reaction based on the viscosity measured by online viscometer or the refraction measured by online refractometer; The online viscometer and refractometer are used to monitor the reaction state, so as to observe the reaction process and to accurately grasp the reaction time to reach the equilibrium point. This way could improve the purity of the product and also monitor the catalytic efficiency of the catalyst.As the catalyst is recycled, it could help to timely replace the catalyst and ensure the continuity of production. This way is very efficient to determine the addition amount of reaction raw materials, so as to more accurately prepare silicone oil and reduce the waste of raw materials.
