  • Patent number: 9969907
    Abstract: A multilayer adhesive film comprising surface adhesive layers, an internal Controlled Bond Layer (“CBL”) comprising a propylene-based polymer strippably adhered to an adjacent layer; an internal Strong Bond Layer (“SBL”) different than the CBL having a facial surface in adhering contact to the CBL and; optionally, one or more different internal Filler Layer(s) located between the SBL and the adhesive surface layer on the side of the SBL opposite to the adhered CBL. In preferred embodiments the adhesive comprises an ethylene/ethylenically unsaturated carboxylic acid copolymer. The adhesive films are used in cable shielding structures.

  • Patent number: 8431198
    Abstract: A multilayer film comprises at least 3 layers including a first outer layer, a second outer layer and between the first and second outer layers at least one core layer. The first and second outer layers each comprise at least 75 weight percent of (a) at least one high impact polystyrene component. The core layer(s) comprises(s) (b) at least one styrene block copolymer that is present at a concentration of at least about 2 weight percent of the polymers in the film; and polymers (a), (b) and (c) at least one general purpose polystyrene having a Mw of more than 200,000 and 350,000 or less and that is present at a concentration of at least about 10 wt. % and up to at most about 50 wt. % of the polymers in the composition account for 100 percent by weight of the polymers in the polymer composition excluding polymeric additives.

  • Patent number: 8187685
    Abstract: The invention includes a composition comprising from 40 to 98 weight percent of at least one GPPS, from 0 to 98 weight percent of at least one HIPS, from 0.5 to 10 weight percent at least one styrene block copolymer, from 0.5 to 10 weight percent of at least one polypropylene wherein the combination of GPPS, HIPS, polypropylene and styrene block copolymer make up at least about 90 percent of the composition as well as a film made of the composition, an envelope window patch comprising the film, an envelope comprising the window patch, and a process for making the film.

  • Publication number: 20120052273
    Abstract: The present invention relates to a multi-layer oriented shrink film comprising a first and a second skin layer comprising a propylene-based polymer having a melting point greater than 130 C and at least one core layer comprising a propylene-based plastomer or elastomer. The films are preferably primarily oriented in either the machine or the cross direction. These films are ideally suited for use as a shrink label which can be applied either as a CD shrink sleeve or applied using a continuous roll process. The films ideally have an overall density of less than 1.0 g/cm3, to facilitate recycling efforts.

  • Patent number: 7824773
    Abstract: A polymer composition containing (a) a high impact polystyrene (HIPS) component with a block copolymer grafted to polystyrene, a rubbery conjugated diene content of one to seven weight percent based on HIPS weight, less than 10 weight-percent gel concentration, an average rubber particle size of between one and 0.01 micrometers, about 40 to about 90 volume percent of the rubber particles have diameters of less than about 0.4 microns and from about 10 to about 60 volume percent of the rubber particles have diameters between about 0.4 and about 2.5 microns, a majority of rubber particles with a core/shell morphology and a concentration that accounts for 10 to 70 weight-percent of the total polymer composition weight and one to five weight-percent rubbery diene based on total polymer composition weight; (b) from 10 to 70 weight percent of a general purpose polystyrene and from about 2 to about 80 weight-percent of a styrene block copolymer component, both based on total polymer composition weight.
