Abstract
A method for manufacturing a grip material consisting of a layer of polyurethane and a layer of EVA. A nylon cloth material is used as a temporary support for coagulating the polyurethane by a wet coagulation process. The coagulated polyurethane is then separated from the nylon cloth material and subsequently joined with a strip of EVA material to yield a grip material with the tackiness and superior shock cushioning characteristics of a polyurethane/felt grip combined with the water resistant and lightness characteristics of a polyurethane/EVA grip.
Claims4
A handle grip, comprising:
- a layer of wet coagulated polyurethane greater than about 0.1 mm thick, having pores which extend through substantially through the thickness of the polyurethane layer;
- a layer of EVA joined to said layer of polyurethane;
- and
- a layer of adhesive on the outer surface of the layer of EVA of the layer to adhere the EVA to the handle grip, wherein the EVA layer provides strength for the coagulated polyurethane, while the coagulated polyurethane cooperates with the EVA to absorb shocks and the coagulated polyurethane also provides tackiness to the outer surface of the grip.
