Polyphenylmethylsiloxane, vinyl terminated, is widely used in the production of high-performance silicone rubbers and resins. Its vinyl groups enable cross-linking reactions, making it a key component in heat-cured and room-temperature vulcanized (RTV) silicone systems. These materials are valued for their thermal stability, electrical insulation properties, and resistance to harsh environments, making them suitable for use in automotive, aerospace, and electronics industries. Additionally, it is employed in coatings and adhesives where durability and flexibility are essential. Its compatibility with other polymers also allows for the creation of hybrid materials with tailored properties for specialized applications.
