Reliable Rubber Inflatable Seal Designs

VMQ (Volatile Magnetic Silicone Rubber) Inflatable seal use methyl vinyl silicone rubber as the base material. High-end models employ a platinum vulcanization process to enhance purity, and some high-pressure applications incorporate a glass fiber reinforcement layer. With its core advantages of high and low temperature resistance, safety, non-toxicity, and aging resistance, it has become the preferred sealing solution for pipelines and valves in food, medical, cold chain logistics, and high-temperature industrial fields. Its application scenarios are concentrated in environments with high hygiene requirements, alternating high and low temperatures, or outdoor exposure. Through a dynamic sealing mode of "inflation and expansion to fit—deflation and contraction to detach," it solves the inflatable seal problems of traditional seals in sanitary pipeline interfaces and extreme temperature valves, while simultaneously ensuring safety and adaptability to various operating conditions.   In…
