Shield Dam Form

Rubber air bag

The material inner layer is composed of a material with high air tightness, and the skeleton material is high strength aramid fiber material. Pneumatic shield rubber dam and rubber dam are using air bag action, due to the material and performance is completely different, so they have a large difference in the life of the. The air shield rubber dam is composed of inner, middle and outer three layers, and the inner layer is a polyester fiber reinforced synthetic rubber, and the middle layer rubber is a monomer synthetic rubber. Through the research and comparison, both material composition and physical mechanical properties are quite different, so the dam bag of rubber dam can not replace the air bag of the air shield gate. From the operation of flexible, reliable operation, the use of life and other considerations, still use the gas shield gate of the airbag.
