Applications of Methylphenylcyclosiloxane:


Used as an important raw material in the synthesis of phenyl-contained silicone oil, silicone resin and silicone rubber. With the introduction of phenyl groups in these silicone polymers, their heat resistance, low temperature resistance, radiation resistant, damping property and refractive Index could be increased.

 

Meanwhile, the introduction of phenyl groups in these polymers, their compatibility with other components could be also improved.


Storage & transportation

 
Keep in cool, shading and dry place, to protect from water, moisture, acid and strong oxidant.


To protect from rain and direct sunlight during transportation.
