Silicone inflatable sealing ring is a composite sealing device that combines silicone material and inflatable structure. It combines the characteristics of silicone material with the flexibility of inflatable expansion, and is suitable for scenarios with high requirements for sealing performance and material. Silicone inflatable sealing rings are widely used in various mechanical pipelines, valves, vulcanization tanks, autoclaves, reaction vessels, dryers, isolators and other sealing equipment. The cross-sectional shape of the inflatable sealing strip is circular, square, rectangular, trapezoidal, M-shaped, etc.
Silicone inflatable sealing ringMaterial Properties
Silicone material has the following characteristics:
Wide temperature resistance range: can be used for a long time from -60 ℃ to+200 ℃, and is not easily deformed or releases harmful substances at high temperatures.
Elasticity and aging resistance: ozone and oxidation resistance, long service life, no yellowing or fading after long-term use.
• Non toxic and environmentally friendly: Compliant with FDA standards, suitable for fields with high hygiene requirements such as food and medicine.
Silicone inflatable sealing ringStructure and Function
Inflatable design enables it to have:
Adjustable seal: By inflating and expanding tightly to fit the gap (with a range of 3-5mm), it can adapt to the deformation caused by temperature changes in cabin doors, pipelines, etc.
Quick installation: After being embedded in the groove, it is fixed with buckles or bolts to simplify the installation process.
• Reusability: After deflation, it can shrink and detach from the contact surface, making it easy to repeat sealing operations.
Silicone inflatable sealing ringMain application scenarios
Industrial sealing: Sealing dust pipelines in the power and chemical industries to reduce maintenance time.
Food processing: Fixing plastic bags in automated canning equipment to improve canning efficiency.
Extreme environment: sealing requirements under high or low temperature conditions.
