  • Latex film compound with improved tear resistance
    Patent number: 7048977
    Abstract: The invention relates to a method of enhancing the tear resistance, tensile strength, and the aging properties of a latex product by adding an antioxidant synergist with an antioxidant to a latex compound comprising of a polymer and a curing system comprised of an activator, crosslinker and accelerator and to the latex products formed therefrom. Antioxidant synergists which can be used with the present invention include 2-mercaptobenzimidazole (MBI), 2-mercaptotoluimidazole (MTI), zinc 2-mercaptobenzimidazole (ZMBI) and zinc 2-mercaptotoluimidazole (ZMTI). The latex products formed may be gloves but can also include threads, balloons and other latex-related products.

  • Accelerator system for synthetic polyisoprene latex
    Patent number: 7041746
    Abstract: The invention pertains to an accelerator system, such as an accelerator system for synthetic polyisoprene latex. The accelerator system comprises dithiocarbamate and thiourea and can produce synthetic polyisoprene films having a tensile strength of about 3,000 psi to about 5,000 psi at low curing temperatures. The invention also pertains to a method for curing synthetic polyisoprene latex.
