For applications requiring maximum resistance to ozone, weather,
flexing and chemicals. Areas of usage include irrigation tubing
tank linings, roof coverings, cable insulation, etc.
Unsaturation 1.5 - 2.0 Mole (%)
Grades with unsaturation in this range and mooney viscosity between
*0 - *0 are the standard butyl grades which are used in the largest
volume. The higher level of unsaturation gives a faster cure rate
and high molecular weight allows high filler loading and a greater
compounding lattitude - Applications include, tubes, bladders,
adhesive a variety of automobile parts like engine mounts, bumbers,
etc.
