polymeric foam that presents pockets or slots to accommodate additional matrices the approaches in which the ids may be made are briefly presented below variations of the procedures briefly described below should be evident to those skilled in the art polymeric coupons particles are mixed in the polymeric melt e g eva pva polysterene and then molded under the desired shape or size alternatively particles can be deposited on the surface of a polymeric surface by means of spraying coating imprinting or in situ deposition polyurethane foam based ids one preferred foam matrix is polyurethane based which is obtained through a process that comprises a mixture of polymers e g pva chitosan isocyanates e g toluene diisocyanate methylene diphenyl diisocyanate polyols e g polyethers and polyesters and organometallic catalysts e g dibutyltin dilaurate and stannous octoate the most preferred polyurethane composition uses the natural polyol castor oil and a decreased amount of isocyanate to obtain foam that is more environmental friendly polymeric films based ids depending on the application films composition may include one or more polymers e g pva chitosan hpmc crosslinkers e g gluteraldehyde uv and heat curing plasticizers e g glycolates citrates ionic liquids and colorants particles are blended in the film composition and the films prepared by casting or extrusion at room.
