Product Performance of Non-standard Inflatable Sealing Rings
Silicone material features excellent sealing properties, high-temperature and weather resistance, anti-aging, shockproof, and waterproof, capable of adhering to various smooth surface materials.
2. High strength, long service life, product is environmentally friendly and insulated, withstanding high and low temperatures, compression, acid and alkali resistance, aging resistance, and UV resistance.
3. Excellent non-stick surface.
4. Made with 100% high-quality silicone material, rigorously tested, and meets environmental standards.
5. High Temperature Resistance: -70°C to 300°C
6. Heat Resistance: Silicone rubber has significantly better heat resistance than regular rubber, allowing for almost indefinite use at 150 degrees Celsius without any performance change; it can be continuously used at 200 degrees Celsius for 10,000 hours; and it can also be used for a period of time at 350 degrees Celsius.
7. Weatherability: Normal rubber degrades rapidly under the action of ozone produced by corona discharge, whereas silicone rubber is unaffected by ozone. Additionally, its physical properties only undergo minimal changes over extended periods of time in UV and other weather conditions.
8. Anti-aging, corrosion-resistant, the silicone itself has a strong inertness.


Shanghai Qingtu Technology Co., Ltd. is a professional manufacturer of various inflatable sealing rings. We can produce large-scale inflatable sealing rings with a circumference of 5 to 10 meters using small molds, significantly reducing the mold investment costs. This also makes the series development of inflatable sealing products a reality. A single mold can produce inflatable sealing rings (parts) with any circumference size while maintaining the same cross-sectional dimensions. The use of inflatable sealing rings greatly saves customers' R&D costs and solves the long-standing issue of poor sealing in large-scale equipment in the industry. With years of experience in producing silicone inflatable sealing rings, our product quality and company strength have been consistently recognized by customers.
