Description
AIRSTOP BUTYL inner tube for MTB wheel 27.5+. Good puncture resistance and pressure maintenance thanks to butyl rubber. BUTYL is a synthetic elastomer obtained by copolymerization of isobutylethylene and isoprene. It has an excellent resistance to extreme temperatures (-60 ° C to + 180 ° C), to bad weather and to aging. Highly waterproof. It has good resistance to concentrated mineral acids (hydrochloric acid, sulfuric acid, fluoric acid, nitric acid, phosphoric acid), to ammonia and concentrated alkaline, halogenated or nitrated derivatives, to organic acids (acetic acid, lactic acid). Michelin offers quality and reliability in all size variants. The air chambers are airtight in all circumstances and offer a very good resistance to perforation, all for an excellent quality/price ratio.
