Key
Characteristics
Low gas permeability. BIIR & CIIR offer improved cure characteristics. |
Further
Comments
This rubber has very high impermeability to gases 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. |
