- Product Highlights
This rubber has very high impermeability to gasses and is hence used for the inner tubes and linings 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 -65°C, it displays high damping at ambient temperatures. It has good ozone, weathering, heat, and chemical resistance. Not suitable for use in contact with mineral oils. It also have low gas permeability, BIIR & CIIR offer improved cure characteristics.
- Features
- Very low air permeability and very good gas barrier properties.
- Excellent electric performance.
- Excellent thermal aging resistance.
