  • Patent number: 6531214
    Abstract: A blend comprising polyolefin and hydrocarbon resin, wherein the polyolefin is semicrystalline and has a suitable degree of crystallinity and molecular weight, or the polyolefin is amorphous and has sufficiently high molecular weight, and sufficient hydrocarbon resin is present in the blend, so that a film made from the blend is substantially vinyl-like and non-elastomeric. Some of the films are also conformable, drapable or affinely deformable by hand.

  • Patent number: 5362516
    Abstract: Method of preparing an adhesive sheet comprising (1) a backing, and (2) an adhesive layer having at least one topologically microstructured surface comprising a plurality of pegs, optionally containing one or more beads, substantially uniformly distributed and protruding outwardly from the adhesive layer, wherein the pegs have essentially flat tops that comprise less than 25% of the total surface contact area of the adhesive layer, and have a height of at least 15 .mu.m.

  • Patent number: 4153661
    Abstract: A polytetrafluoroethylene composite sheet having a tensile strength of at least one megapascal and comprising particulate material distributed in a matrix of interentangled polytetrafluoroethylene fibrils. The composite sheet is prepared by blending the particulate material with polytetrafluoroethylene aqueous dispersion in the presence of sufficient lubricant water to exceed the absorptive capacity of the solids yet maintain a putty-like consistency, subjecting the putty-like mass to intensive mixing at a temperature between 50.degree. C. and 100.degree. C. to cause initial fibrillation of the polytetrafluoroethylene particles, biaxially calendering the putty-like mass to cause additional fibrillation of the polytetrafluoroethylene particles while maintaining the same water content and drying the resultant sheet.
