  • Low application temperature elastic attachment adhesive
    Patent number: 7799863
    Abstract: Low application temperature thermoplastic hot melt adhesives are particularly useful as elastic attachment adhesives. The adhesives have a viscosity at 275° F. of less than about 8,000 cp, a yield stress of less than about than 80 psi and a creep performance for a bond made through strand coating of less than about 15%. Preferred are adhesives that have a creep performance for a bond made through spiral coating of less than about 25%.
    Type: Grant
    Filed: January 31, 2005
    Date of Patent: September 21, 2010
    Assignee: Henkel AG & Co. KGaA
    Inventors: Qiwei He, Michael G. Harwell, Ju-ming Hung, Martin Riswick, Wei Kong, Kenneth E. Martin, Tahir Iqbal

  • Polymer coating for powder-free elastic strands
    Publication number: 20050244640
    Abstract: The present invention is directed to a coated elastomeric sheet or strands having a polymeric coating applied to both sides. The powder-free polymer coating provides good release and anti-blocking properties to elastic strands, as well as adding to the machinability and end-use properties of the strands. The polymer-coated elastic strands are useful in the manufacture of diapers and other disposable articles requiring flexible elastic-lined openings.

  • Disposable absorbent product
    Patent number: 5591154
    Abstract: This invention discloses that styrene-butadiene-styrene block copolymers containing 30 to 50% by weight styrene and additionally having been polymerized in such a manner as to obtain a vinyl content of greater than about 35% may be used in adhesives to achieve desirable low viscosity of 1000 to 3500 cps at 160.degree. C.
