PVMQ - Phenyl Silicone
Phenyl silicone – or methyl phenyl silicone – is a polydimethylsiloxane with phenyl groups. The phenyl content improves various properties such as oxidation resistance, thermal stability, shear resistance and optical clarity.
Typical applications for use with connectors for cables and sealing for automotive and aerospace markets where ultra low temp is required.
The most prominent characteristic is flexibility at extreme temperatures, with operational ranges between -90 °F to +500 °F. Also, by blending phenyl silicone with silicone and fluorosilicone elastomers, we can optimise properties of the overall material.
Poor impermeability to gas, not resistant to hydrocarbon-based fuels, aromatic hydrocarbons (benzene, toluene), low molecular weight silicone oils, strong acids and alkalis. It is regarded as mechanically weak.
