Corocel™ Expanded PVC Sheets
Coroplast introduces Corocel™, an expanded high density polyvinyl chloride (PVC) sheet.
Corocel™ is rigid, only a little more than half the weight of solid PVC sheet.
Corocel™ can be printed, painted, glued, laminated, cut, welded or thermoformed. It is easily fabricated using conventional equipment and techniques.
Corocel™ can be used in a variety of applications, including signs and displays for advertising; heat and sound insulation, interior design, partitions and paneling for construction; transport containers and model making.
Corocel™ sheets are supplied with a protective film masking on one side to shield its surface from dust.
The masking eliminates the need to clean the surface prior to printing or painting.
