ELASTOMERIC RUBBER GLOVE FOR APPLICATION IN CLEANROOMS AND NOT CONTAINING VULCANIZATION ACCELERATORS AND SULFUR Russian patent published in 2017 - IPC C08J5/02 C08L13/02 C08L33/20 A41D19/00 

FIELD: chemistry.

SUBSTANCE: glove for cleanrooms is manufactured from elastomer containing 25-30 wt % of acrylonitrile, 62-71 wt % of butadiene and 8.4 wt % of unsaturated carboxylic acid (total 100 wt %), as well as a chemically active vinyl compound and a metal crosslinking agent. At that, the glove does not contain sulfur as a crosslinking agent or a vulcanization accelerator. Crosslinking is achieved by application of a reactive vinyl compound and a part of carboxyl groups of unsaturated carboxylic acid, and the remainder of the carboxyl groups is bound through the metal cross-linking agent, such as zinc oxide. Glove thickness is 0.050.15 mm, its manufacturing swelling ratio is 240-320, glove tensile stress is 22-35 MPa, elongation to break is 480-620%, and tensile stress at 500% glove elongation is 15-35 MPa.

EFFECT: according to the invention, the glove is characterized by the lack of stickiness on the surface which contacts the user's hand, and the glove surface that is in contact with an object during operation, is smooth, metal or metallic salt contained in the glove as contaminants are removed, and the content of metal, metal salt and anion is reduced.
