Methyl Phenyl vinyl silicone Gum MY 3120 PVMQ





Methyl Phenyl vinyl silicone Gum MY 3120 PVMQ

Other Names: Phenyl Vinyl Methyl Silicone, Poly Dimethyl Diphenyl Vinyl Siloxane, PVMQ

Properties :
Methyl phenyl vinyl silicone gum contains a large number of phenyl groups in the raw rubber molecule. In addition to the high temperature resistance and dielectric properties common to methyl vinyl silicone rubber, it also has better radiation resistance and burning resistance. corrosion resistance, physical and mechanical properties and excellent low temperature performance. This product is insoluble in water, soluble in toluene, etc., with small compression deformation. Excellent characteristics of resistance to saturated vapor pressure.


Advantage :

It has a certain degree of flexibility at minus 110 ℃, and products produced as basic raw materials can be used well in ultra-low temperature working environments;
Long term storage stability;  
Has good damping performance;
Good radiation resistance effect;
High consistency, low volatility, no odor, excellent thermal stability.
