Customize hollow inflatable seals with Qingtu Rubber. These seals are used to seal gaps between mechanical parts, expanding to seal when inflated and returning to their original shape when deflated, allowing the machine to resume operation.

Hollow inflatable sealing rings are a new type of seal made of silicone rubber, featuring an internal hollow structure. These seals are designed for use with compressed air sources and utilize inflation and deflation to alter the structural shape of the silicone rubber seal. Due to the flexibility of silicone rubber, the inflated seal becomes malleable. Upon contact with the sealing surface, the expanded seal undergoes flexible curve deformation, enabling it to seal gaps that are linear or curved. Upon deflation, the seal automatically retracts to its original shape, restoring the equipment gap. They can quickly achieve and release sealing, with repeated inflation and deflation capable of up to 1 million cycles. In operation, the internal gas pressure of the seal body ensures high sealing strength, resulting in excellent sealing performance. The shape of the hollow structure of the seal body is designed based on the sealing gap size, fluid pressure, and expansion/contraction frequency. Similar to solid-core seals, inflatable seals can achieve radial and axial sealing for equipment.

Silicone withstands high temperatures and tearing, and remains unaffected by most chemical media except for strong acids and bases, making it an ideal material for inflatable sealing. Hollow inflatable seals are widely used in various mechanical pipelines, valves, vulcanizing tanks, autoclaves, reactors, dryers, separators, and other sealing equipment.
