PROCESSO PARA FABRICACAO DE UM ARTIGO MODELADO EXTRUDADO A PARTIR DE UMA COMPOSICAO DE BORRACHA DE SILICONE LIQUIDA

摘要

Extruded articles such as filaments and films are fabricated by blending the components of a curable liquid silicone rubber composition at temperatures of from -60 to +5 C and then extruding the composition into water maintained at a temperature of at least +25 C to cure said composition. The water bath preferably contains a surfactant to facilitate processing of the extruded article. The present method provides uniformly cured articles that are almost bubble-free and have low shrinkage ratios.
