Performance Characteristics of IOTA 3120 Methyl Phenyl Vinyl Silicone Rubber

The performance of IOTA 3120 Methyl Phenyl Vinyl Silicone Rubber is influenced by several factors, including vinyl content, vinyl position, and phenyl content. Higher vinyl content increases the cross-linking ratio, resulting in higher hardness and tensile strength but lower elongation and compression set. The position of vinyl groups also plays a role, with vinyl-terminated raw rubber offering better performance due to molecular chain growth during cross-linking.
Phenyl content significantly affects the functional properties of the silicone rubber. Low phenyl content provides the best low-temperature resistance, medium phenyl content enhances damping performance, and high phenyl content improves radiation resistance. These characteristics make IOTA 3120 a highly adaptable material suitable for a wide range of industrial applications, from aerospace to medical devices.
