APPLICATION AREAS
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.

Substance of little danger
as for the effect on human organism and does not have properties
of allergic product, is not toxic.
Butylrubber must be stored
in a good ventilated production premise protected from the effect
of direct sunlight, atmospheric precipitation at the temperature
of 400℃.
Guaranteed storage time - 1 year starting
from the production day.
