Dynacast Industrial Products Butyl Rubber - BUTYI

Dynacast Industrial Products Butyl Rubber - BUTYI has a very high impermeability to gasses and is used for the inner tubes of pneumatic tires, and in vacuum and high pressure applications. It has an unusually broad loss peak so that, despite having a glass transition temperature as low as -65C, it displays high damping at ambient temperatures. Butyl Rubber has good ozone, weathering, heat and chemical resistance. It is not suitable for use in contact with mineral oils. Butyl rubber has low resilience at ambient temperatures and is suitable for damping applications.
