Abstract

L'invention concerne des articles élastomères profilés, par exemple des gants, des préservatifs, et des sacs respiratoires, préparés à partir d'une composition mélangée de polymères. Cette composition renferment environ entre 10 et 90 parties en poids d'un polymère de chloroprène, et environ entre 10 et 90 parties en poids d'un polymère de nitrile, sur la base de 100 parties en poids du polymère total. Une fois durci, cet article présente une épaisseur variant entre 0,05 et 50 mils, une résistance à la traction d'au moins 9 MPA, et une élongation atteignant au moins 300 %. Lorsque cet article est étiré pour venir s'ajuster sur un membre du corps humain, par exemple la main, il exerce une pression initiale avant de se relâcher de manière à exercer une pression réduite, qui atteint au moins 50 % de ladite pression initiale. Cette invention concerne également un mélange de chloroprène et de nitrile, permettant de produire des articles provoquant une sensation et une fonctionnalité équivalente ou similaire à celles d'un gant classique en latex de caoutchouc naturel. Ces articles donnent donc une sensation équivalente ou meilleure que les gants en vinyle ou en nitrile actuellement disponibles.
