Semi-rigid display board

In a graphic display installation, a semi-rigid flat display board, comprising:

• a flat relatively soft elastomeric foam core substrate defining a first side and an opposite second side formed from one or more from the group consisting of EVA, nylon, polyethylene, EMA or urethane;
• a first outer film layer laminated to the first side of the elastomeric foam core substrate and a second outer film layer laminated to the second side of the elastomeric foam layer, the first and second outer film layers intimately confining the core substrate, thereby producing a relatively harder semi-rigid display board characterized by compression and tension rebound;
• a flat display graphic printed or mounted on the first outer film layer, wherein
• the foam core substrate is a closed cell cross-linked foam with the closed cells having diameters within an approximate range of 0.1-0.5 mm, a durometer hardness within an approximate range of 20-100 measured on the Shore 00 scale, a tensile strength value within an approximate range of 550-850 kPA, and a tensile elongation value within an approximate range of 100-200%,
• the semi-rigid display board is self-supporting and inherently remains flat when configured in an upright position,
• the display board is mounted on a surface or hung from a structure in the upright position with the display graphic exposed,
• and
• the first outer film layer is adhered to the first side with a thermoplastic adhesive, and the adhesive and the elastic foam core comprise the same thermoplastic material.

A semi-rigid flat display board, consisting essentially of:

• a flat relatively soft elastomeric foam core substrate defining a first side and an opposite second side and formed from one or more from the group consisting of EVA, nylon, polyethylene, EMA or urethane;
• a first outer film layer laminated to the first side of the elastomeric foam core substrate and a second outer film layer laminated to the second side of the elastomeric foam layer, wherein
• the outer and inner film layers intimately confine the core substrate, thereby producing a relatively semi-rigid display board characterized by compression and tension rebound;
• the foam core substrate is a closed cell cross-linked foam with closed cells having diameters within an approximate range of 0.1-0.5 mm, a durometer hardness within an approximate range of 20-100 measured on the Shore 00 scale, a tensile strength value within an approximate range of 550-850 kPA, and a tensile elongation value within an approximate range of 100-200%,
• the semi-rigid display board is self-supporting and inherently remains flat when configured in an upright position,
• the first outer layer has a smooth, flat, exposed surface adapted to receive a flat display graphic printed or mounted thereon, and
• the first outer film layer is adhered to the first side with a thermoplastic adhesive, and the adhesive and the elastic foam core comprise the same thermoplastic material.
