  • Controlled-puncture films
    Patent number: 6869666
    Abstract: The present invention discloses methods of controlling the puncturability, and optionally the sealability (the ability of a film to conform around a puncturing object) and resealability (the ability of a film to close a hole made by a puncturing object), of polymeric films. Systems comprising a film and puncturing object are also disclosed. Puncturability is controlled by achieving targeted levels of the friction between the film and a puncturing object, the film's flexural rigidity, the film's recovering stress, and the film's elongation at break.
    Type: Grant

  • Blended pressure-sensitive adhesives
    Patent number: 6632522
    Abstract: A pressure-sensitive adhesive comprising a blend of at least two components, wherein the first component is at least one pressure-sensitive adhesive and second component is at least one thermoplastic material, wherein the components form a blended composition having more than one domain and, wherein one domain is substantially continuous (generally, the pressure-sensitive adhesive) and the other domain is substantially fibrillous to schistose (generally, the thermoplastic material). The second component can be (a) at least one thermoplastic elastomer, (b) at least one elastomer with a tackifying resin or (c) at least one elastomer.

  • Elatomeric laminates and composites
    Patent number: 6436529
    Abstract: Microtextured elastomeric materials having at least one elastomeric core layer or region and at least one skin layer wherein the skin layer has a semi-crystalline or amorphous polymer and an elastomeric block copolymer or pressure sensitive adhesive, the combination of which is less elastic than the core layer and will undergo permanent deformation at the stretch percentage that the elastomeric laminate will undergo. The materials are suited for use in applications such as respirators.
