The Challenge Lowering defect rates in tire manufacturing In tire manufacturing, low defect rates are an important factor in improving productivity. Defect rates tend to be high when tire producers use low performing release agents in tire curing. This occurs as these products are not fully providing all the functions required. A performing release agent must insure the creation of a continuous protective release film on the bladder. This film represents a durable barrier between the bladder and the uncured tire. Any sticking of the uncured rubber to the bladder surface is so avoided. The release film on the bladder surface must insure a high slip level during the numerous release cycles. This is to insure perfect centering of the bladder inside the tire to promote optimum tire balance. Du
