A dip-formed article includes a laminate in which a rubber layer is laminated on a fiber base material. The thickness of the rubber layer is 0.2 to 0.8 mm, the rubber constituting the rubber layer penetrates into the fiber base material, the maximum depth to which the rubber has penetrated into the fiber base material is 0.1 to 0.3 mm, and the maximum stress at 50% elongation of the laminate is 20 N or smaller.

Dip-formed article and protective glove

A latex composition has a latex of a carboxyl group-containing conjugated diene rubber and a metal compound including a trivalent or higher metal, wherein a content of the metal compound is 0.1 to 1.5 parts by weight, based on 100 parts by weight of the carboxyl group-containing conjugated diene rubber.

Latex composition and film molded body

A copolymer latex of a copolymer comprising 50 to 88 wt % of a conjugated diene monomer unit, 10 to 40 wt % of an ethylenically unsaturated nitrile monomer unit, and 2 to 10 wt % of an ethylenically unsaturated acid monomer unit, the copolymer latex having an insoluble content in methyl ethyl ketone of 70 wt % or less and a swelling degree in methyl ethyl ketone of 40 times or more when the copolymer is formed into a dry film.

Copolymer latex

A rubber formed article includes a laminate in which a rubber layer of nitrile rubber is laminated on a fiber base material. The nitrile rubber contains a copolymer having 52 to 78% by weight of conjugated diene monomer units, 20 to 40% by weight of &#x3b1;,&#x3b2;-ethylenically unsaturated nitrile monomer units, and 2 to 10% by weight of ethylenically unsaturated monocarboxylic acid monomer units. Stress at 50% elongation of the laminate is 20 N or smaller. A ratio of an area where rubber is visible when the laminate is viewed from the back side to an area of the laminate is 15% or less. The thickness of the rubber layer is 0.30 mm or less.
