  • Patent number: 10150893
    Abstract: An uncured adhesive contains 2 to 10 weight percent of particles of a semi-crystalline organic material, preferably a polyester having a number-average molecular weight of 2000 to 10,000, a hydroxyl number of 10 to 60, and a melting temperature of 50 to 125° C. The adhesive is applied by heating it just prior to application, to melt the particles. After application, the adhesive is cooled to below the melting temperature of the semi-crystalline organic material, and then cured. The process allows the adhesive to be stored and pumped at ambient temperatures, due to the moderate viscosity of the material. Upon melting and re-cooling the semi-crystalline organic material, the adhesive assumes a high yield stress that imparts very good wash-off resistance. In preferred embodiments, the adhesive composition includes an epoxy resin and an epoxy curing agent.

    Abstract: A process for the production of PET foams includes the extrusion of a mixture of PET, epoxy resin, catalyst consisting of imidazole, derivatives of imidazole or mixtures thereof plus a blowing agent, wherein the homopolymerization reaction of the epoxy phase is performed in the extruder, upstream of the introduction of the blowing agent. Compared to the methods of the known art, a process according to the invention offers the advantage of providing a stable PET foam, in which the structure of the polymer chains is kept unaltered. The system therefore has viscoelasticity characteristics which allow the PET/epoxy homopolymer to receive the expanding action of the blowing agent, as far as the innermost and deepest layers of foam also even if they have a significant thickness.

    Abstract: A breathable film formed from a thermoplastic composition that contains a rigid renewable polyester and has a voided structure is provided. To achieve such a structure, a thermoplastic composition that contains a renewable polyester and polymeric toughening additive is extruded onto a surface to form a precursor film in which the toughening additive can be dispersed as discrete physical domains within a continuous matrix of the renewable polyester. The precursor film is thereafter stretched or drawn at a temperature below the glass transition temperature of the polyester (i.e., “cold drawn”). Without intending to be limited by theory, the present inventors believe that the deformation force and elongational strain of the drawing process causes debonding to occur in the renewable polyester matrix at those areas located adjacent to the discrete domains. This creates a network of voids located adjacent to the discrete domains.

    Abstract: Bilayer platelet fillers are employed to compensate for a positive coefficient of thermal expansion (CTE) of an embedding polymeric material, or even to provide a composite structure having a negative CTE to eliminate or alleviate thermomechanical stress and/or delamination during thermal cycling. A bilayer platelet includes two joined layers having different CTEs. The CTE mismatch induces bending of the bilayer platelets, thereby causing cavities at temperatures lower than the joining temperature at which the bilayers are joined. The decrease in the volume of the polymeric material and the bilayer platelets at low temperatures is compensated by an accompanying increase in the volume of the cavities so that the composite structure has a temperature independent volume, a low net CTE, or even a negative CTE.

  • Patent number: 7473715
    Abstract: The present invention relates to methods, materials, and products for forming a foamed product, comprising the steps of combining an epoxy-based component with an amine-based component. The epoxy component is cross-linked through a polymerization reaction catalyzed by the amine formulation. In this regard, an reactive mixture or exothermic reaction is created between the epoxy component and the amine component when combined. The heat generated by the exothermic reaction softens a thermoplastic shell of a blowing agent formulated within the epoxy component thereby enabling a solvent core within the thermoplastic shell of the blowing agent to expand from the heat generated by the exothermic or reactive mixture.

  • Patent number: 7119149
    Abstract: The present invention is directed to a high expansion two-component structural foam that expands to about twice its original volume while maintaining good cell structure. The foam of the present invention is based on epoxy resins. Each component of the foam system exhibits storage stability, e.g., no phase separation, yet reacts when combined to provide a cured material having exceptionally good compression strength and modulus. The blowing system used to prepare the foam produces a foam which is uniform in appearance and is essentially free of the large voids often found in conventional two-part thermosettable compositions, even when a relatively large mass is utilized.

  • Patent number: 7115673
    Abstract: The present photosensitive resin composition 2 comprises a polyamic acid resin 4, a photosensitive agent, a dispersible compound 3 dispersible in the polyamic acid resin 4, and a solvent. The porous resin is obtained by removing the solvent from the photosensitive resin composition 2 to form a composition in which the dispersible compound 3 is dispersed in the polyamic acid resin 4, removing the dispersible compound to make the composition porous, and curing the porous photosensitive resin composition. The porous resin enables forming a fine circuit pattern and has a low dielectric constant and, when used as an insulating layer of a circuit board, brings about improved high frequency characteristics.
