Patent number: 11505672Abstract: The disclosed latex system comprises a one-component, closed-cell, semi-foam, mastic sealant using gas-filled, flexible, organic microspheres to create a product that is elastic and compressible under pressure without protruding in an outward direction when compressed, thereby allowing the applied sealant to compress in an enclosed, maximum-filled channel unlike typical mastic sealants (while retaining the ability to rebound). This allows the sealant to function as a gasket, and, once fully cured, to have properties including vibration damping, insulating, and condensation resistance. The sealant can be formulated as an air barrier or a vapor barrier and at various degrees of moisture resistance. It may be applied by different packaging variations including aerosol can (bag in can or bag on valve), airless sprayer, cartridge tubes, foil tubes, squeeze tubes, and buckets to be applied using a brush, trowel, spatula, etc.Type: GrantFiled: April 29, 2020Date of Patent: November 22, 2022Assignee: Polymer Adhesive Sealant Systems, Inc.Inventors: Sandra Kocurek, Devin Kocurek, Jonathan Perriello

Patent number: 8889574Abstract: A laminate product comprising a foam core having a pair of opposed major surfaces and a cover layer secured with respect to each major surface is described. The cover layer comprises a polymeric substrate having disposed therein a plurality of reinforcing fibrous material. It has been found that it is possible to produce a foam laminate product having improved stiffness if a lower amount of reinforcing material is used for a given amount of polymer substrate. In particular, it has been found possible to provide an improved foam laminate product having a relatively high ratio of stiffness to weight of reinforcing fibrous material. It has been further discovered that the stiffness of the resulting foam laminate product can be increased when the polymer substrate and the reinforcing fibrous material are present in a weight ratio of greater than 2.5. This is believed to be the result of improved encapsulation of the reinforcing fibrous material by the polymer substrate.Type: GrantFiled: April 27, 2006Date of Patent: November 18, 2014Assignee: Proprietect, L.P.Inventors: Inna Dolgopolsky, Yolanda Sadl, Lisa Pileggi, Petar Pepic

Publication number: 20140326532Abstract: A composite foam cushion for a sound control device. The cushion includes a core formed of a polymeric foam material and a polymeric coating overlying at least a portion of the core of polymeric foam material. The polymeric coating includes an outer coating layer and an inner polymeric coating layer bonded to the core of polymeric foam material. The inner coating layer may provide the cushion with strength, while providing a high degree of flexibility and suppleness to closely conform around contours and obstructions. The outer coating layer may provide the cushion with enhanced abrasion resistance and/or chemical resistance while having an aesthetically pleasing feel and appearance.Type: ApplicationFiled: May 29, 2014Publication date: November 6, 2014Applicant: Hearing Components, Inc.Inventors: Justin C.

Patent number: 8846191Abstract: 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.Type: GrantFiled: October 11, 2012Date of Patent: September 30, 2014Assignee: International Business Machines CorporationInventors: Gareth G.
