A flexible, elongated handle-wrapping strip for tennis racquets, bicycle handlebars, baseball bats, fishing poles, or any other desired use which comprises a first layer of a composite of cork granules, the cork granules being plasticized with a liquid organic polyol and bonded to each other in a flexible plastic binder material. A second layer of contact adhesive is provided on one side of the first layer, while a third, peel-sheet layer overlies the contact adhesive layer for peeling away, to expose the contact adhesive layer for use. The handle-wrapping strip may be helically wound with the parallel edges of adjacent coils being in contact with each other. The adhesive layer is in the form of a flexible plastic sheet coated on both sides with an adhesive. The first layer includes 40 parts by weight of the cork granules plasticized with 3 to 20 parts by weight of the liquid polyol. The wrapping strip may also include a plastic layer of 0.01 to 0.05 inch thickness between the layer of cork and the adhesive.
An elongated, flexible handle-wrapping strip which comprises a first layer of a composite of cork granules, each 40 parts by weight of said cork granules being plasticized with 3 to 20 parts by weight of a liquid organic polyol and bonded together in a flexible plastic binder material;
An elongated, handle-wrapping strip which comprises a first layer of a composite of cork granules which are predominantly of a size between 1/8 and 1/18 inch, said first layer being from 0.02 to 0.1 inch thick, said cork granules being plasticized with a liquid organic polyol and bonded together in a flexible plastic binder material, said first layer comprising, per 40 parts by weight of cork granules, from 3 to 20 parts by weight of said liquid organic polyol plasticizer for the cork;
An elongated, handle-wrapping strip which comprises a first layer of a composite of cork granules which are predominantly of a size between 1/8 and 1/18 inch, said first layer being from 0.03 to 0.06 inch thick, said cork granules being plasticized with glycerine and bonded together in a flexible binder material, said first layer comprising, per 40 parts by weight of cork granules, from 4 to 10 parts by weight of said glycerine, from 10 to 30 parts by weight of polyvinyl chloride resin, and from 10 to 25 parts by weight of an organic plasticizer for polyvinyl chloride;
