Patent

CA 2370505

Powder-free natural rubber and synthetic elastomeric articles, in particular, gloves, having an inner coating of a nitrile rubber with an intermediate layer of a rubber blend comprised of natural or synthetic rubber and nitrile rubber interposed between the nitrile coating and the base glove and their method of manufacture are described. The intermediate layer of the rubber blend interposed between the coating and the glove imparts a unique surface texture to the glove which aids donning and eliminates self-sticking of the inner glove surfaces, especially after the glove has been sterilized by radiation. Additionally the gloves of the invention exhibit good grippability, good donnability, superior tensile strength, elongation to break and stress at 500 % elongation.

L'invention concerne, d'une part, des articles en caoutchouc naturel exempts de poudre et en élastomères de synthèse, en particulier des gants, recouverts d'un revêtement intérieur en caoutchouc nitrile et équipés d'une couche intermédiaire faite d'un mélange de caoutchouc à base de caoutchouc naturel ou synthétique et de caoutchouc nitrile placée entre le revêtement en nitrile et le gant d'origine et, d'autre part, de la technique de fabrication connexe. La couche intermédiaire faite d'un mélange de caoutchouc, placée entre le revêtement et le gant, confère à ce dernier une texture superficielle unique qui favorise son enfilement et élimine l'auto-adhérence de sa surface intérieure, notamment aprés stérilisation par irradiation. En outre, les gants selon l'invention présentent une bonne adhérence, une facilité d'enfilement, ainsi qu'une résistance à la traction et un allongement à la rupture supérieurs et une contrainte à un allongement de 500 % inférieure.
