CAMRETAINER is an air-bubble co-extruded PP board. A new patented technology, it is a co-extruded board made of three layers: a central thermoformed core, and two flat, compact “external skins” with “matte” finishes. This 9.SMM thick, high-density board delivers protective rigidity along with moisture and chemical resistance. CAM RETAINER is made from 100% recyclable polypropylene and the unique internal components provides outstanding rigidity, tensile strength, and flexural modulus.
