Semi-steel B- type curing bladder is a key component used in the curing process of semi-steel radial tires.

1. basic concepts
The vulcanizing bladder is a hollow thin-walled rubber product of the tire vulcanizer, which is specially designed to be filled into the inner cavity of the tire blank to be vulcanized. During the vulcanization process, a heating medium (such as hot air, nitrogen or superheated water, etc.) is introduced into the capsule to cooperate with a vulcanizer for tire shaping and vulcanization. The semi-steel B- type curing bladder is a specific type of bladder designed for the curing process of semi-steel radial tires.

2. function and role
Shape retention: The semi-steel B- type curing bladder plays a supporting role inside the tire to ensure that the tire maintains the correct shape and size during the curing process.
Vulcanization medium: The heating medium in the bladder is used as a vulcanization medium to promote the vulcanization reaction of the tire material by heating and pressurizing to achieve the expected physical and chemical properties.
Improve quality: The use of semi-steel B- type vulcanization bladder can significantly improve the vulcanization quality and consistency of tires, and enhance the wear resistance, impact resistance and service life of tires.
