1. A multi-layered flexible taping material, comprising: a rubber layer, wherein the rubber layer comprises a plurality of at least three polychloroprene polymer sheets, each sheet having a first end, a second end, and a length therebetween;a heat sensitive adhesive layer comprising polyurethane polymer; anda layer of release paper, wherein the adhesive layer covers substantially an entire lower surface of the rubber layer and is disposed substantially between the rubber layer and the release paper, wherein each sheet has its first end or its second end spliced together with the first end or the second end of an adjacent sheet such that the length of the rubber layer is substantially equal to or greater than the total lengths of the at least three sheets. 2. The multi-layered flexible taping material according to claim 1, further comprising a fabric layer, wherein the fabric comprises knit or woven fabric. 3. The multi-layered flexible taping material according to claim 1, wherein the release paper covers substantially an entire lower surface of the adhesive layer. 4. The multi-layered flexible taping material according to claim 2, wherein the rubber layer is disposed substantially between the heat sensitive adhesive layer and the fabric layer. 5. The multi-layered flexible taping material according to claim 1, wherein the polychloroprene comprises neoprene. 6. A method of manufacturing a multi-layered taping material, comprising: providing a first sheet of polychloroprene rubber, a second sheet of polychloroprene rubber, a third sheet of polychloroprene rubber, a sheet or film of heat-sensitive polyurethane adhesive, and a sheet of release paper, wherein each of the first sheet, the second sheet, and the third-sheet of polychloroprene rubber comprises a first end, a second end, an upper surface and a lower surface, and the sheet or film of heat-sensitive polyurethane adhesive comprises an upper surface and a lower surface;placing the second end of the first sheet of polychloroprene rubber adjacent to the first end of the second sheet of polychloroprene rubber;splicing together the second end of the first sheet of polychloroprene rubber and the first end of the second sheet of polychloroprene rubber;placing the first end of the third sheet of polychloroprene rubber adjacent to the second end of the second sheet of polychloroprene rubber;splicing together the first end of the third sheet of polychloroprene rubber and the second end of the second sheet of polychloroprene rubber;laminating the upper surface of the sheet or film of heat-sensitive polyurethane adhesive to the lower surfaces of the first, second, and third sheets of polychloroprene rubber; andattaching the sheet of release paper to the lower surface of the heat-sensitive polyurethane adhesive. 7. The method according to claim 6, further comprising attaching a layer of fabric to the upper surfaces of the first, second, and third sheets of polychloroprene rubber. 8. The method according to claim 6, wherein the polychloroprene comprises neoprene. 9. The method according to claim 6, wherein the first, second, and third sheets of polychloroprene rubber are spliced-together using splicing tape. 10. The method according to claim 6, further comprising rolling the laminated sheets on a core. 11. The method according to claim 6, wherein each of the first, second, and third sheets of polychloroprene rubber has a length of at least about 2 meters. 12. The method according to claim 6, wherein each of the first, second, and third sheets of polychloroprene rubber has a thickness of between about 0.02 mm and about 0.05 mm. 13. The method according to claim 10, further comprising slitting the rolled sheets into smaller rolls. 14. The multi-layered flexible taping material according to claim 1, wherein the rubber layer comprising a plurality of polychloroprene polymer sheets has a length of at least about 6 meters. 15. The multi-layered flexible taping material according to claim 1, wherein each of the plurality of polychloroprene polymer sheets has a thickness of between about 0.02 mm and about 0.05 mm. 16. The multi-layered flexible taping material according to claim 1, wherein the plurality of polychloroprene polymer sheets are spliced together with splicing tape. 17. The multi-layered flexible taping material according to claim 1, wherein the taping material is in a form of a roll. 18. The multi-layered flexible taping material according to claim 1, wherein the fabric layer comprises a plurality of fabric layers. 19. The multi-layered flexible taping material according to claim 1, wherein the polyurethane polymer comprises a softening point of between about 120° C. and about 134° C.
