Un método de fabricación de un guante elastomérico sintético que tiene: (a) un espesor en la palma de menos de 0,05 mm; y al menos uno de (b) un módulo al 500 % por encima de 6,5 MPa; y (c) un alargamiento de rotura por debajo de 700 %, el método comprende: - sumergir un formador con forma de guante en una composición coagulante con una concentración de coagulante de 0,5 - 10 % en peso; - sumergir el formador con forma de guante en una composición elastomérica formadora de película con un contenido total de sólidos de entre 3 % y 15 % en peso; y - secar y/o curar la composición elastomérica formadora de película sobre el formador para producir el guante elastomérico sintético. The present application provides low thickness synthetic elastomeric gloves, comprising (a) a thickness at the palm of less than 0.050mm; (b) a modulus at 500% above 6.5 MPa; and/or (c) an elongation at break below 700%. Also provided is a method for the manufacture of such gloves involving dipping a glove-shaped former into an elastomeric film-forming composition; and curing the elastomeric film-forming composition on the former so as to produce the synthetic elastomeric glove. Corresponding low thickness finger cots are also described, as are formers suitable for the preparation of such gloves.
