Shaped elastomeric articles such as gloves, condoms and breather bags, are
prepared from a polymer blend composition comprising about 10 to about 90
parts by weight of a chloroprene polymer and about 10 to about 90 parts by
weight of a nitrile polymer, based on 100 parts by weight of total polymer.
The cured article has a thickness of 0.05 to 50 mils, a tensile strength of at
least 9 MPA and an elongation of at least 300 %. The article, when stretched
to fit over a human body member such as a hand, exerts an initial pressure,
but thereafter relaxes to exert a reduced pressure which is no less than 50 %
of the initial pressure. This invention provides a blend of a polychloroprene
and a nitrile polymer that yields products of equivalent or similar feel and
functionality compared to the common natural rubber latex glove. These
products provide equal or better feel than nitrile or vinyl gloves currently
available.
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.
