Beschreibung
Zusammenfassung:	2102230 9220538 PCTABS00017 Disclosed is at least a two-layered chlorinated polyethylene film for use as an inner liner for a pneumatic rubber substrate or a tire, with an inner layer adjacent an inner surface of the rubber substrate comprising an adhesive resin; and an outer layer consisting essentially of chlorinated polyethylene containing from 35 to 50 % by weight chlorine, a derivative of 2,5-dimercapto 1-3,4 thiadiazole as a curative, an accelerator, an acid acceptor, and optionally containing carbon black. The film is from 0.13 mm (5 mil) to 0.76 mm (30 mil) in thickness, and has oxygen permeability from 6x10-12 to 36x10-12cc-cm/cm2-cmHg-sec (10 to 60 cc-mil/100 sq.in.-atm-day). The film containing carbon black typically has an intermediate layer of a thermoplastic elastomer interposed between the adhesive layer and CPE layer. Further disclosed is a pneumatic rubber substrate or a tire incorporating chlorinated polyethylene films of the present invention.
