  • Patent number: 11827813
    Abstract: A PVC-based cover strip designed to bond to non-PVC materials as well as PVC materials includes a PVC layer coated with a barrier effective to prevent migration of plasticizers from the PVC layer. The barrier layer, in turn, is coated with a primer and subsequently a pressure-sensitive adhesive. The barrier layer is generally a polar polymer, such as acrylonitrile rubber which resists migration of phthalate plasticizers. The pressure-sensitive adhesive layer is a pressure-sensitive adhesive suitable for use in roofing applications.

  • Publication number: 20150141567
    Abstract: This invention relates to an alloy comprising polyurethane and polyolefin. It has now surprisingly been found that a specific composition of polyolefin and polyurethane has surprising mechanical properties and at the same time has transparent characteristics and/or appearance. The present invention provides an alloy with remarkable mechanical properties. The phases do not macro-phase separate. Thus, this stable and potentially broad interface is very effective in stress transfer when the alloy is strained. As one might expect, the hardness values for the alloys are in between the hardness values of each component but the other physical properties are no adjusted. In this way, when considering the hardness and mechanical values, these alloys behave like two compatible polymers.
