Fatigue-resistant integral molded gas seal

Integral molded inflatable seal exhibit superior fatigue resistance through synergistic optimization of materials, structure, and process. Their core characteristics can be summarized as follows:   I. Material Properties: The Cornerstone of Fatigue Resistance High Elasticity and Low Permanent Deformation Utilizing high-performance elastomers such as silicone and fluororubber, they can still recover 98% of their original dimensions under high-pressure cycling (e.g., 1000 consecutive compressions at 120 mmHg), with a permanent deformation rate of <2%, far superior to ordinary rubber (8%-15%).   Case Study: After 500,000 inflation/deflation cycles, the leakage rate of the sealing ring in a medical pneumatic therapy device is ≤0.1 L/min, ensuring long-term precise sealing.   Structural Design: Enhanced Fatigue Resistance Integral Molding Process Through high-temperature, high-pressure vulcanization in a single molding process, splicing gaps are eliminated, stress concentration points a…
