  • Patent number: 4900608
    Abstract: A flexible epoxy coated fabric has good hand, good wear resistance, good hydrolytic resistance, and good ultraviolet light resistance. An optional but desirable binder is a true coating and not an impregnation of the fabric in that at least 50 percent of the binder material resides on the surface of the fabric. A flexible epoxy material is utilized as a coating and generally has an intermediate hydrocarbon portion having at least 25 carbon atoms for each chain. The fabric is suitable as a substitute for leather in clothing, and upholstery as in automotive upholstery.

  • Patent number: 4574103
    Abstract: A laminate comprises fused adherent layers of plastisol vinyl chloride polymer resins in which a first layer contains Sb.sub.2 O.sub.3 and a second layer contains TiO.sub.2. The flexible laminate is useful as a roofing membrane for the roof of a building wherein the layer containing the Sb.sub.2 O.sub.3 is adjacent a structural or insulation member of the roof of the building while the TiO.sub.2 layer can be exposed to the elements and can protect the Sb.sub.2 O.sub.3 layer from sunlight.

  • Patent number: 4256797
    Abstract: An improved contoured resilient vehicle trim panel and method of making same which is suitable for use as a decorative headliner adjacent to the interior undersurface of the roof panel of vehicles. The trim panel comprises a composite laminar sheet consisting of a pair of imperforate thermoplastic films disposed in spaced-apart relationship and tenaciously bonded in supported relationship to the face surfaces of an intervening coextensive thermoplastic foam core layer. The films and the closed cell foam core are comprised of a thermoplastic polymer having a glass transition temperature of at least 200.degree. F. and a tensile modulus of at least 1.0.times.10.sup.5 psi. A variety of decorative coatings and films can be secured to the concave face of the laminar sheet so as to achieve the desired decorative appearance.
