  • Patent number: 10538609
    Abstract: A synthetic polyisoprene latex emulsion has pre-vulcanization composition and post vulcanization composition. The pre-vulcanization composition comprises soluble sulfur with high S8 ring structure that is catalytically broken by a zinc dithiocarbamate. Surfactants present in the pre-vulcanization composition wets synthetic polyisoprene particles and permeates small sized sulfur and accelerator molecules into the interior of these particles thereby pre-vulcanizing the particles. The degree of pre-vulcanization is verified by isopropanol index test. The latex emulsion has post-vulcanization composition with accelerators that crosslink inter-particle region during post vulcanization cure cycle. The dipped synthetic polyisoprene article is substantially uniformly cured both in the inter-particle and intra-particle regions and reliably exhibits high cross link density, uniform distribution of double bonds in TEM and zinc segregation at the boundaries or original particles by electron microprobe analysis.

  • Patent number: 8881784
    Abstract: The invention relates to a device for inserting inside tires of a vehicle so that it follows its course without stopping after a bursting. The device comprises a cluster of flexible bladders (1) which are made of rubber, have a diameter of one to several inches according to the use, are interconnected by a cord (2.1) with its distribution branches (2.2, 2.3) and an inflating stem (3). The air enters each bladder via the cord by means of a very sensitive mini-check valve (9). During inflation, the air contained inside the space of the tire is purged via a purging system (6, 7, 8). In one variant, the principle of the valves, cord and purge is retained, but there are fewer bladders and they have the shape of sections of the tire. Bladders that are resistant to depression can also be used with the same valves and purge but without a cord. The refilling ensues by an over inflation step followed by a reduction effected by the purge until the operating pressure is reached.

  • Publication number: 20140322468
    Abstract: Provided are methods for surface-modifying a rubber vulcanizate or a thermoplastic elastomer, the methods forming a surface with a chemically fixed lubricant instead of resin coating which has drawbacks, such as that the coating is, for example, removed or peeled during the movement within a vessel, whereby the lubricity is reduced. The present invention relates to a method for surface-modifying an object of a rubber vulcanizate or a thermoplastic elastomer, the method including step 1 of forming polymerization initiation points on a surface of the object, and step 2 of radically polymerizing a deliquescent monomer starting from the polymerization initiation points by irradiation with ultraviolet light having a wavelength within the range of 300 to 400 nm, to grow polymer chains on the surface of the object.
