The application describes applying a thin thermoplastics layer e.g. about 25 &mgr;m thick on the surface of the natural rubber so that it can conveniently be welded to another thermoplastics component such as a hot-melt tape. The thermoplastics layer (4,5) may cover the whole or only a marginal part of the rubber article. It may be formed by dipping into a thermoplastics latex. The thermoplastics layer may cover the whole or only a margin of the rubber article. Polyurethane is one suitable material. By providing a non-tacky weldable region the invention is more convenient to use than previous proposals using adhesives.

  • Patent number: 6465591
    Abstract: A polymer useful in forming coatings for articles is provided. The polymer is an acrylic copolymer formed as the reaction product of a plurality of monomers which include an alkyl (meth)acrylate, a quaternary amine (meth)acrylate, a hydroxyalkyl (meth)acrylate, an N-vinyl lactam, an ethylenically unsaturated carboxylic acid, and a fluorinated (meth)acrylate. The polymer is formed in the presence of surfactants, preferably by sequential polymerization of two separate monomer mixtures. To form a coating, the polymer is blended with an elastomeric material such as nitrile rubber latex. The resulting coating is useful both as a print coating for substrates used with ink jet printers and as a coating for rubber articles.

  • Patent number: 6372323
    Abstract: A slip control article including a backing layer having a first surface with an array of at least 100 upstanding stems per square inch and a second surface. At least a portion of the upstanding stems is an elastomeric material and the stems have an aspect ratio of at least 1.25. The first surface has a static coefficient of friction when dry of at least 0.6 and a static coefficient of friction when wet within 20% of the static coefficient of friction when dry. The first surface has a peel strength and a tensile strength of substantially zero when engaged with another slip control article. The first surface has a relatively high shear strength when engaged with another slip control article. The high shear forces are due primarily to the frictional properties of the elastomeric materials, not a mechanical interlock of the stems, such as on a mechanical fastener.

  • Publication number: 20020022142
    Abstract: A semiconductive rubber composition is provided having superior electrical properties, such as superior uniformity, small voltage dependence, small environmental dependence, and stability with time. In addition, the semiconductive rubber composition can be used for forming a charging member which suppresses contamination of a member to be charged, such as a photosensitive member. In the semiconductive rubber composition, a dispersed domain structure is formed having a polymeric continuous phase composed of an ion conductive rubber material primarily containing a raw rubber A having an intrinsic volume resistivity of 1×1012 &OHgr;·cm or less and a polymeric dispersed phase composed of an electron conductive rubber material and conductive particles mixed therewith.

  • Patent number: 6258193
    Abstract: Methods for fabricating laminations to form structural elements of predetermined shapes (120, 220, 420, 520, 620) are provided. Laminations include parts (22, 24) fabricated from the tread portion (42) of discarded rubber tires. The parts are typically arranged in layers with various relationships therebetween. The parts are pressed to remove all voids therebetween causing dynamic tension which creates rigidity and then bonded with methods including vulcanization, chemical vulcanization, epoxy and adhesive.
