BK-1675N - for the fabrication of inner tubes, diaphragms for vulcanizes, rubberized fabrics.


Butylrubber has a low gas stream penetrability, good dielectric properties, is stable against the influence of oxygen, ozone, acids, alkalis, sunlight, high temperatures in humid and dry conditions, animal butter and fats and vegetable oils.

Butylrubber is badly combined with other types of high-unsaturated elastomers (NR, SKI-3, etc.). The vulcanization is accomplished with more active accelerators and at more elevated temperatures.
