Surgical gloves were manufactured using the RVNRL process. A fractional factorial design at two levels showed that five parameters of the coagulant dipping process which were studied independent. Coagulant concentration and dwell time in the radiovulcanized latex presented major main effects while the temperature of the former before dipping into the radiovulcanized latex and the flow time of the radiovulcanized latex on the former surface presented opposite main effects. The withdrawal rate of the former from the radiovulcanized latex did not change glove thickness. The mathematical correlation between the estimates of thickness and the significant main effects of coded variables was = 0.212 + 0.025x1 + 0.019x2. This optimized equation allowed reproduction of a surgical glove thickness in the range of 0.157 to 0.291mm, which is considered acceptable by international standard specification

RESUMEN [2]. El gran interés por los sistemas con arcillas se debe a su estructura laminar con dimensión nanométrica [1,6,10,11]. El resultado de la relación entre el área superficial y el espesor es una gran área interfacial que permite un alto grado de interacción con el polímero, lo que implica un alto índice de refuerzo para poca carga incorporada. La mayor parte de los estudios se realizan utilizándose arcillas sintéticas del tipo Motmorillonita-sódica pero, las motmorillonitas naturales, comúnmente identificadas como bentonitas, son las más importantes [5; 12]. La capacidad de intercambio de cationes de las arcillas permite la rápida formación de un coloide con la adición de agua. Es necesario modificar las arcillas para que presenten superficies organofílicas, ya que ___________________________________________________________________________________________
