Abstract
This application relates to elastomeric articles such as gloves, compositions for producing the articles and methods for their manufacture. The elastomeric articles contain particles for detectability of the articles (or portions thereof) by metal detectors and/or x-ray detectors. The articles may contain magnetic particles, highly conductive particles, or high atomic mass element-containing particles, and a viscosity modifier to ensure dispersion of the particles throughout the film layer in which the particles are present. The particles may be magnetic particles specifically, and may be coated by a corrosion inhibitor coating.
Claims16
A dipped elastomeric article comprising an elastomeric film with a thickness in the range of 0.01-2.0 mm, the elastomeric film containing one or more film layers, wherein at least one film layer comprises:
- at least one type of particles selected from:
- (a(i)) magnetic particles, wherein the magnetic particles are selected from the group consisting of ferromagnetic particles based on at least one of iron, nickel, and cobalt, and ferrimagnetic particles;
- and
- (a(ii)) conductive particles having electrical conductivity of at least 3.0×107 S/m at 20° C. dispersed throughout the film layer, and
- a pseudoplastic viscosity modifier for achieving the dispersion of said particles throughout the film layer,
- wherein:
- the particles are coated by a corrosion inhibitor and/or a corrosion inhibitor is dispersed throughout said film layer, said corrosion inhibitor being selected from the group consisting of silicones, waxes, corrosion-inhibiting polymers, corrosion-resistant metal salts, corrosion-resistant metals and combinations thereof;
- each of said one or more film layers is formed by dipping a former into a film-forming composition having a total solids content of between 5 and 50% which comprises:
- (b(i)) an elastomer-forming polymer consisting of nitrile rubber, or non-carboxylated polychloroprene, or a combination thereof;
- and
- (b(ii)) a cross-linking agent, so as to produce said elastomeric film with the thickness in the range of 0.01-2 mm;
- and
- the dipped elastomeric article has:
- (c(i)) a modulus at 500% elongation of between 1.0 and 25 MPa;
- and
- (c(ii)) an elongation at break of at least 100%.
A dipped elastomeric article comprising an elastomeric film with a thickness in the range of 0.01-2.0 mm, the elastomeric film containing one or more film layers, wherein at least one film layer comprises magnetic particles dispersed throughout the film layer, wherein the magnetic particles are coated by a corrosion inhibitor, and the magnetic particles are selected from the group consisting of ferromagnetic particles based on at least one of iron, nickel, and cobalt, and ferrimagnetic particles,
- wherein:
- the corrosion inhibitor is selected from the group consisting of silicones, waxes, corrosion-inhibiting polymers, corrosion-resistant metal salts, corrosion-resistant metals and combinations thereof;

- (a(i)) an elastomer-forming polymer consisting of nitrile rubber, or non-carboxylated polychloroprene, or a combination thereof;
- and
- (a(ii)) a cross-linking agent, so as to produce said elastomeric film with the thickness in the range of 0.01-2.0 mm;
- and
