Type A patches are designed for repairing most fabrics, canvas, rubber, neoprene, nylon, Sunbrella, Gore-tex, polyester, hypalon, Dacron, non-oiled leather, acrylics, aluminum, fiberglass and plastics such as polyethylene, polypropylene, polyurethane. TEAR-AID Repair Patches provide a simple and easy method of patching holes and tears, as well as an excellent protective film solution. Each TEAR-AID Repair Patch is made from an exceptionally tough, matte finish, abrasion resistant, elastomer that resists puncture and tearing. It is combined with an aggressive adhesive formulated for high bond strength. Tear-Aid expands absorbing force on impact and always returns to original shape and size. This flexibility allows the patch to conform to irregular surfaces without restricting the movement of the repaired material.
