A colorable, low-durometer grade of Santoprene(reg) rubber is used in the FreeBoard(TM) Beamer wireless keyboard. The Santoprene rubber allowed the black keyboard to be color-differentiated from its padded areas, which are charcoal gray. Soft thermoplastic elastomer (TPE) pads are injection-molded from a colorable Santoprene rubber grade with 73 Shore A hardness to cushion the hands.
