ABSTRACT:
A high pressure laminate (HPL) is disclosed for use on an access floor panel. The HPL is comprised of a rigid, moisture, impervious melamine plastic layer laminated under high pressure and heat to a substrate layer comprised of a resin paper element of multiple sheets of phenolic resin impregnated kraft paper. This resin paper element has at least one groove in it, wherein material has been removed to a depth sufficient to sever enough paper sheet grain lines of the resin paper element so that, after the HPL has been adhesively bonded to the HPL receiving surface of an access floor panel, vertical expansion or contraction of the resin paper element will note elongate the bond line in the area from the edge of the HPL to the groove that creates the pivot or hinge line. An access floor panel is also disclosed.
