Product details

Reinforced fabric inflatable seal are elastic elements that achieve sealing through internal air pressure regulation. Their core principle utilizes the compressibility of gas and the elasticity of rubber to form a tight sealing interface under the influence of internal and external pressure differences. After inflation, the seal's tube wall expands and tightly adheres to the sealed surface, filling irregular gaps (such as dynamic gaps of 3-5mm or more), forming a continuous sealing line or surface. After depressurization, the seal quickly retracts, reducing contact wear and opening/closing resistance. This design allows it to adapt to complex working conditions and maintain a stable sealing effect over long-term use.

I. Core Advantages: Dynamic Sealing and Adaptive Adjustment Reinforce rubber seal achieve dynamic control of sealing strength through internal air pressure regulation. After inflation, the seal's tube wall expands and tightly adheres to the sealing surface, filling irregular gaps (such as dynamic gaps of 3-5mm or more), forming a continuous sealing line. For example, when such seals are installed on refrigerated truck doors, inflation maintains a sealed environment, reducing the impact of external temperature fluctuations on goods and extending shelf life.

Extreme Environmental Resistance

Temperature Resistance: Silicone material maintains elasticity within a temperature range of -60℃ to 250℃, suitable for extreme conditions such as aerospace and chemical industries.

Chemical Corrosion Resistance: Fluororubber enhances molecular structural stability through the introduction of fluorine atoms, maintaining inflatable seal performance even after long-term contact with strong acids, strong alkalis, or high-temperature fuels.

Aging Resistance: Ethylene propylene diene monomer (EPDM) rubber resists UV and ozone aging in outdoor environments, with a service life of over 10 years.

High Elasticity and Sealing Reliability: Rubber has a low elastic modulus and high elongation. After inflation, it can generate significant deformation through minor stress, providing continuous contact pressure to compensate for leakage gaps. For example, inflatable sealing strips in semiconductor manufacturing workshops isolate dust and harmful gases, maintaining cleanliness; shock-absorbing seals in automotive suspension systems reduce the impact of vibration on equipment through elastic cushioning.

Customization and Installation Convenience

Custom Size: Supports segmented vulcanization technology to manufacture irregularly shaped sealing rings with a circumference exceeding 5 meters, eliminating the need for large molds and reducing costs by over 60%. For example, a custom-designed inflatable sealing strip for a large warehouse door has a circumference of 8 meters and accommodates a 12mm sealing gap.

Functional Integration: Through surface coating or embedded metal frame, combined functions such as electrical conductivity, thermal conductivity, or enhanced mechanical strength can be achieved. For example, in electronic component manufacturing equipment, inflatable sealing strips with integrated conductive coatings improve electrostatic discharge efficiency by 90%.
