The Corner Shelf developed by Shelfworks Technologies Inc. of Englewood, N.J., relies on Versaflex TPE supplied by GLS Corp. The TPE is overmolded onto a polypropylene pad incorporated into a shelf unit.
The TPE-covered pad is pushed against a wall when a consumer pushes a knob on the shelf. Friction created by pressing the TPE against the wall holds the shelf in place. Turning the knob to unlock it frees the shelf and makes removal easy, Shelfworks said.
GLS of McHenry, Ill., had to meet several requirements for a TPE blend to work. Besides easy processing, the TPE has to cool flat after overmolding. The elastomer must adhere well to a range of materials, including glass and painted drywall, without damaging the substrate when removed.
Consistency and colorability are also demanded, the firm noted.
