A LAMINATED CARBOXYLATED ACRYLONITRILE BUTADIENE LATEX SEAMLESS BLADDER AND A PROCESS FOR MANUFACTURING THEREOF

摘要

A laminated seamless bladder involving latex dipping process comprising of carboxylated aciylonitrile latex or blended with one or more type of latex selected from a group comprising neoprene latex, heat resistant grade natural latex, styrene-butadiene rubber latex, or a mixture thereof and laminated by pasting with a layer of rubber selected from a group comprising synthetic rubber, natural rubber, or a mixture thereof and a process for manufacturing therof. The said bladder having good air retention and bounce characteristics, controlled inflation rate without involving thread breading. The said process of manufacturing the bladder involving low manufacturing cost, high productivity and low rejection rate. The above said bladder being made of a film having desired thickness varying from about 0.70 mm to 3.00 mm, and weight varying from about 700 mg/inch² to about 1.5 g/inch² without any problem of processability and suitable for machine stitched as well as hand stitched inflatable balls.
