Patent ID: 8629192

Claim:
A method for producing a High Internal Phase Emulsion foam comprising the steps of: forming a first High Internal Phase Emulsion from an oil phase comprising monomer, cross-linking agent, emulsifier; an aqueous phase; and photoinitiator; forming a second High Internal Phase Emulsion from an oil phase comprising monomer, cross-linking agent, emulsifier; an aqueous phase; and photoinitiator; depositing the first High Internal Phase Emulsion on a belt; depositing the second High Internal Phase Emulsion on the first High Internal Phase Emulsion; producing a High Internal Phase Emulsion foam by polymerizing the monomers of the first and second High Internal Phase Emulsion by exposing the first and second High Internal Phase Emulsion to UV light provided by a UV light source; wherein the first layer allows UV light to reach the second layer so that the first layer or second layer are capable of being polymerized simultaneously; and wherein the belt comprises a UV reflective material in the form of microparticles having an average size of about 1 to 100 μm.
