Abstract

Tynnveggede gummiartikler for anvendelseskontakt med levende vev eller med materialer som skal leveres til levende vev er fremstilt fra vandig lateks av enten naturlig gummi eller syntetisk cis-1,4-polyisopren ved vulkanisering for å produsere både karbon-karbon og karbon- (svovel) n-karbon tverrbindinger, vulkaniseringen utføres i fraværet av enhver kompounderende komponent som inneholder sekundære amingrupper eller enhver komponent som har en tendens til å produsere nitrosaminer. Mens svovelaktivatorer kan være inkludert, er det foretrukket at ingen svovelakselerator inkluderes i det hele tatt. Tynnveggede gummiartikler formet fra lateks utviser overraskende en kombinasjon av høy strekkstyrke, høy ultimat prosent forlengning, og lav 500% strekkmodus. Prosessen er spesielt effektiv i tilvirkingen av tynnveggede artikler fra syntetisk cis-1,4-polyisopren.
