Elastomeric rubber and rubber products without the use of vulcanizing accelerators and sulfur

Abstract

A composition for producing an elastomeric thin film comprising a carboxylated acrylonitrile polybutadiene latex which is vulcanized without the use of conventional sulphur and accelerators thereby reducing the possibility of contacting immediate Type I hypersensitivity and delay Type IV hypersensitivity caused by the presence of natural rubber latex proteins and accelerators respectively. The dipping process for making gloves by using a latex composition provided by: premixing carboxylated acrylonitrile polybutadiene latex with methacrylic acid, or alternatively using a self-crosslinked latex, adding zinc oxide, adjusted to 9 to 10 of the pH level, and diluted with water to obtain 18% to 30% by weight of total solid content; dipping the glove former into the composition to form a layer of thin film of the latex composition on the former; drying the thin latex film on the former and crosslinking the latex film on the former.
