  • Use of microwave energy to selectively heat thermoplastic polymer systems
    Patent number: 9303152
    Abstract: A method for processing a thermoplastic material that comprises a microwave-sensitive polymeric region, wherein the method includes exposing the microwave-sensitive polymeric region to microwaves; wherein the exposing results in an increase in the temperature of the polymeric region; and processing the thermoplastic material is disclosed.
    Type: Grant
    Filed: May 31, 2007
    Date of Patent: April 5, 2016
    Assignee: DOW GLOBAL TECHNOLOGIES LLC

  • Heat bonding polyurethane foams
    Patent number: 8535476
    Abstract: A process for producing a laminate or composite structure comprises heat bonding a substrate to a polyurethane foam, wherein the polyurethane foam is produced using at least one natural oil derived polyol as at least a portion of the polyol used in making the polyurethane foam. The resulting laminate or composite structure comprises at least one foam produced from a polyol composition comprising at least one natural oil derived polyol and at least one substrate with the interface between the foam and substrate being that formed by heat bonding. The invention also includes any article comprising such a laminate or composite structure.
