  • SUSTAINABLE POLY(VINYL HALIDE) MIXTURES FOR THIN-FILM APPLICATIONS
    Publication number: 20160260519
    Abstract: A mixture of poly(vinyl halide) and epoxidized benzyl fatty acid ester, preferably epoxidized benzyl soyate (EBS), is disclosed. The epoxidized benzyl fatty acid ester as a plasticizer replaces common high molecular weight phthalates, such as diisodecyl phthalate (DIDP), which are conventionally used for the manufacture of wire and cable insulation and jacketing. The epoxidized benzyl fatty acid ester, a bio-plasticizer, unexpectedly outperforms the higher molecular weight DIDP as demonstrated by superior retention of Strain at Break after accelerated aging at elevated temperatures.

  • ANTIMICROBIAL POLYMER CONCENTRATES AND COMPOUNDS
    Publication number: 20160235072
    Abstract: Migratory assisting agents are used to improve antimicrobial efficacy of antimicrobial masterbatches, the polymer compounds these antimicrobial masterbatches are let down into, and the articles made therefrom. The migratory assisting agents function by carrying the antimicrobial agents while the migratory assisting agent transfers or “migrates” to the surface of a polymer compound or article formed from the polymer compound. As a result, antimicrobial agents are brought to the surface where there is exposure to bacterial contamination.

  • RADIOPAQUE, OPTICALLY TRANSLUCENT THERMOPLASTIC COMPOUNDS
    Publication number: 20160220735
    Abstract: A radiopaque, optically translucent thermoplastic polyurethane compound is disclosed. The use of nano-sized particles of barium sulfate optionally in combination with a minor amount of certain dispersion aids allows the barium sulfate to be sufficiently dispersed within the thermoplastic polyurethane to retain optical translucency according to a defined Haze Determination Test. Medical devices, needing both visual spectrum observation before and during in-vivo medical use and radiopacity monitoring during in-vivo medical use, benefit from this compound. Optionally, a surface enhancer can also be used.

  • PREPARATION OF IMIDE OLIGOMERS VIA CONCURRENT REACTIVE EXTRUSION
    Publication number: 20160215095
    Abstract: Reactive extrusion can be used in a continuous, solvent-less preparation of imide oligomers involving two competing reactions among three ingredients, the first reaction between a dianhydride and a diamine and the second reaction between an endcap and the same diamine. The imide oligomer can form a composite via conventional production methods or via formation of a film from imide oligomer re-melted in an extruder before being impregnated into tape or fabric.

  • Crosslinkable bioplasticizers
    Patent number: 9382415
    Abstract: A crosslinkable bioplasticizer is disclosed, a mixture of an epoxy-functional bio-derived plasticizer and an aromatic dianhydride. When heated, the mixture crosslinks, which can be accelerated by the addition of a Lewis Acid metal catalyst. The crosslinked bioplasticizer can be melt compounded into a thermoplastic resin or can be formed in situ in the thermoplastic resin. The crosslinking of the bioplasticizer can reduce blooming of the bioplasticizer to the surface of a plastic article made by extrusion, molding, calendering, or thermoforming techniques.

  • ACRYLIC-URETHANE IPN PLASTISOL
    Publication number: 20160152857
    Abstract: Plastisol compositions having a two-resin interpenetrating polymer network (IPN) are disclosed. The compositions begin with blocked isocyanate grafted acrylic polymer, blocked isocyanate urethane prepolymer, plasticizer, optionally pigment, and optionally thixotropic agent. When subjected to a thermal cure, the isocyanate groups on the acrylic polymer and urethane prepolymer both become unblocked and both react with the crosslinking agent to form an interpenetrating acrylic-polyurethane network. The two-resin IPN offers improved storage stability, hand-feel characteristics, and processing properties for textile printing among other uses. Preferably these plastisol compositions are essentially free of polyvinyl halides and phthalates restricted for regulatory reasons.
