Title (EN) MEDICAL RADIATION ATTENUATION NATURAL RUBBER THIN FILMS, METHODS OF MAKING AND ARTICLES MADE THEREWITH
(FR) FILMS MINCES EN CAOUTCHOUC NATUREL D'ATTÉNUATION DE RAYONNEMENT MÉDICAL, PROCÉDÉS DE FABRICATION ET ARTICLES FABRIQUÉS AVEC CEUX-CI
Abstract:
(EN) Medical radiation attenuation thin films, methods of making the same, and articles such as gloves made therefrom, are disclosed. The thin films utilize guayule natural rubber, sulfur and an attenuation filler such as Bi2O3. The films mix the guayule natural rubber, sulfur and attenuation filler and cure the mixture at about 80 to about 105°C for about 40 to about 90 minutes.
(FR) L'invention concerne des films minces d'atténuation de rayonnement médical, des procédés de fabrication de ceux-ci et des articles tels que des gants fabriqués à partir de ceux-ci. Les films minces utilisent du caoutchouc naturel de guayule, du soufre et une charge d'atténuation telle que le Bi203. Pour obtenir les films, le caoutchouc naturel de guayule, le soufre et la charge d'atténuation sont mélangés et le mélange est durci à environ 80 jusqu'environ 105°C pendant environ 40 à environ 90 minutes.
