  • Thermoplastic elastomer with desirable grip especially during wet conditions
    Patent number: 9573347
    Abstract: Thermoplastic elastomer compositions having a desirable soft touch feel to skin, and in particular grip, especially during wet, soapy and humid conditions. In one embodiment, the composition is part of a composite system, wherein the composition is connected, for example molded, overmolded or co-extruded to a substrate, such as a thermoplastic, glass or metal. The compositions and composites are suitable for use wherever desirable feel and grip are needed, such as handles or grips of household or industrial items.

  • Tube assembly and method for making the assembly
    Patent number: 9345853
    Abstract: A tube assembly including a flexible tube joined to a connector with the tube having an insert liner located therein at least in an area of a distal end of the connector that provides improved retention force between the tube and connector. Methods for preparing the tube assembly are disclosed and include the use of adhesives or solvent for bonding the tube to the connector.

  • Adhesive system, method of assembly of distinct components therewith
    Patent number: 8871864
    Abstract: An adhesive system including a cyanoacrylate adhesive composition having a polymerization retarder that slows the polymerization rate of the cyanoacrylate, increases the lubricity to achieve proper assembly and aids in achieving desirable bonding properties of the adhesive; and a phosphorous-based primer that assists in preparing the components to be bonded. Methods of connecting dissimilar materials, preferably those used in medical applications, utilizing the adhesive system and the resulting adhered assemblies are disclosed.

  • Curable adhesive system, method of assembly of distinct components therewith
    Patent number: 8871317
    Abstract: An adhesive system including a synergistic combination of a light curable silicone-containing adhesive composition and an amine-containing primer composition that provides desirable bond strength between two articles preferably one of the articles including a polyolefin or polyolefin-based thermoplastic elastomer. Methods of connecting articles, preferably those utilized in fluid transfer applications, utilizing the adhesive system and the resulting adhered assemblies are disclosed.

  • Sealing elements and sealing element compositions
    Patent number: 8552117
    Abstract: Polyolefin based sealing element compositions with good oxygen barrier properties particularly suitable for forming sealing elements, for example gaskets and cap liners that are especially useful for sealing containers having products such as liquids or food-stuffs therein. The compositions when formed as sealing elements do not appreciably contribute taste and/or odor to a packaged product including the sealing element. The compositions have desirable rheological properties and are thus readily processable at various temperatures.
