FIELD: polymer materials.
SUBSTANCE: invention relates to a composition appropriate for manufacturing air bladder, which composition comprises at least one butyl rubber, rubber extender, polybutylene softener having number average molecular mass at least 700 and viscosity at 100°C within a range of 10 to 6000 cSt, and at least one curing agent. Composition contains no semicrystalline polymers. Extender can be selected from materials such as calcium carbonate, clay, mica, carbon black, and mixtures thereof. Air permeability of cured compositions of invention ay 65°C lies within a range of 1 to 4.5·10-8 cm3·cm/cm2·s·at.
EFFECT: improved antiaging properties of air bladder.
