Semi Steel Radial R16 Tire Curing Bladder(PCR)NO.7

Tire curing bladders, also known as curing bladders, are key tools in the tire vulcanization process, mainly made of butyl rubber. Its function is to inject compressed air, nitrogen or superheated water during the tire vulcanization process to form internal pressure and vulcanize the tire. The design and material of this capsule ensure that it can quickly conduct heat, work efficiently during use, and is easy to operate with low labor intensity.The types of tire curing bladders are divided into several types according to the different vulcanization machines and fixtures, including oblique A type, oblique B type, oblique AB type, meridian A type, meridian B type, and meridian AB type. These types of capsules have different applications and specific design requirements during the vulcanization process. For example, the capsules used in diagonal tires may be designed in a barrel shape, while radial tires may use orange shaped capsules.The service life of capsules is influenced by various factors, including high temperature, high elongation, and oxidation resistance. In order to extend the service life of the capsule, its formula design should focus on high temperature resistance, reducibility after high elongation, and permanent deformation at break. In addition, the elongation ratio of the capsule during the vulcanization process is an important parameter. The elongation ratio of diagonal tires is generally between 1.6 and 1.85, while that of radial tires is between 1.10 and 1.15.The design of tire curing bladders also includes specific exhaust channels and patterns, which have a significant impact on the vulcanization quality of the tire. For example, the capsule body may have non patterned parts, diagonal exhaust channels, and diamond exhaust channels, which help improve exhaust efficiency during the vulcanization process and tire quality.
