Methyl Phenyl vinyl silicone Gum MY 3120 PVMQ

High-performance silicone rubber raw materials MY 3120 Methyl Phenyl vinyl silicone Gum PVMQ

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

Properties :
MY 3120 PVMQ silicone rubber are specifically designed for extreme environments (ultra-high temperature, ultra-low temperature, radiation, corrosion). This product combines phenyl modification and vinyl crosslinking capabilities, exhibiting excellent thermal stability, low-temperature flexibility, mechanical properties, and chemical/radiation resistance, making it an ideal choice for high-end sealing materials, electronic insulation, aerospace, and medical cryo-sealing applications.

Advantage :
- Contains a large number of phenyl groups, providing excellent high-temperature resistance and dielectric properties.
- Maintains a certain degree of flexibility at low temperatures (usable down to approximately -110 °C)—suitable for extremely low-temperature environments.
- Excellent resistance to radiation, corrosion, and saturated vapor pressure.
