Abstract
An abrasion-resistant halogenated isobutylene-based rubber composition having good traction characteristics is disclosed. In a preferred embodiment, the composition comprises a halogenated isobutylene rubber, styrene/butadiene rubber and polybutadiene rubber combined with carbon black and a silane-coupled silica filler. In automobile tire treads, tire retreads, and other anti-skid materials, the composition exhibits viscoelastic properties offering excellent traction and good rolling resistance with no loss in tire treadwear.
