Custom large inflatable circles? Choose Qingtu Rubber.
Silicone materials offer excellent sealing properties, high temperature and weather resistance, anti-aging, shockproof, and waterproof capabilities, and can adhere to various smooth surface materials.
High strength, long service life, product is environmentally friendly and insulated, withstanding extreme temperatures, compression, acid and alkali resistance, aging resistance, and UV protection.
3. Excellent non-stick surface properties.
4. Made with 100% high-quality silicone material and strictly tested to meet environmental standards.
5. High Temperature Resistance: -70°C to 300°C
6. Heat Resistance: Silicone rubber boasts significantly better heat resistance than ordinary rubber, allowing for nearly perpetual use at 150 degrees Celsius without performance degradation; it can be continuously used at 200 degrees Celsius for 10,000 hours; and it can also withstand temperatures up to 350 degrees Celsius for a certain duration.
7. Weather Resistance: Ordinary rubber degrades rapidly under the action of ozone produced by corona discharge, whereas silicone rubber is unaffected by ozone. Moreover, its physical properties change minimally over long periods in UV light and other climatic conditions.
8. Anti-aging, corrosion-resistant, with strong inertness, silicone itself is highly inert.

Shanghai Qingtu Technology Co., Ltd. is a professional manufacturer of large-scale inflatable sealing rings. We can produce large inflatable sealing rings with a circumference of 5 to 10 meters using small molds, significantly reducing the mold investment cost. This also makes the serialization 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 dimension. The use of inflatable sealing rings greatly saves customers' R&D costs and solves the issue of poor sealing in large-scale equipment, a problem that has plagued the industry for years. With nearly two decades of experience in producing silicone inflatable sealing rings, our product quality and company strength have been consistently recognized by customers. We are a factory specializing in the production of silicone inflatable rings.
