IOTA 3120 is a premium methyl phenyl vinyl silicone rubber gum engineered for demanding and extreme operating conditions. By incorporating phenyl groups into the silicone polymer backbone, this material offers enhanced low-temperature flexibility, improved damping behavior, superior radiation resistance, and stable mechanical performance compared with conventional methyl vinyl silicone rubber.

The rubber maintains elasticity and flexibility at ultra-low temperatures down to –110°C, effectively reducing the risk of brittleness or performance loss in cold environments. In addition, its low compression set, excellent thermal stability, low volatility, and odor-free characteristics ensure long-term reliability and consistent quality during storage and use.

Thanks to its optimized vinyl content and uniform molecular structure, IOTA 3120 delivers stable vulcanization behavior and balanced physical properties, making it suitable for applications where durability, safety, and performance consistency are critical.

Typical Applications:

• Low-temperature sealing, insulation, and vibration-damping components in aerospace and electronics

• Rubber parts requiring damping and shock-absorbing performance

• Radiation-resistant, high-temperature, and ablation-resistant silicone rubber products

• Medical and healthcare applications such as low-temperature sealing and medical tubing
