Product Overview
Multilayer gas-barrier film engineered to replace the ~1 mm thick butyl / halobutyl rubber inner-liner of modern radial tyres — significantly reducing weight and improving fuel efficiency while maintaining gas-barrier performance under millions of flex cycles. Covered by Kuraray (EVOH-based) and Kolon Industries (polymer film) patents. Also covers interleaf / separator films (LDPE / LLDPE / PET, 25 – 75 µm) used between uncured rubber components.
