Abstract
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.degree. to +5.degree. C. and then extruding the composition into water maintained at a temperature of at least +25.degree. 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.
