Jinlong Polyester TPU Fabric integrates the high-strength framework of polyester base fabric with the functional performance of TPU, striking an ideal balance between lightweight handling and structural integrity. The polyester base fabric delivers excellent tensile and tear strength, effectively compensating for the weakness of pure TPU film-its tendency to stretch and deform under stress. The modified TPU layer provides superior airtightness, waterproofing, and low-temperature flexibility. Together, they form a composite that stands up to prolonged water exposure, intense sunlight, and extreme temperatures in demanding outdoor environments.
The key challenge in bonding polyester with TPU lies at the interface between the two materials. Jinlong addresses this through interface activation and low-temperature lamination processes, achieving a strong bond with significantly improved peel strength while carefully controlling temperatures to prevent yellowing or delamination. To address the risk of hydrolysis degradation in humid conditions, Jinlong incorporates an anti-hydrolysis protection system into the formulation, significantly slowing material degradation and ensuring reliable sealing and mechanical performance over the long term in liquid storage or outdoor exposure applications.
Thanks to these technical advancements, Jinlong polyester TPU fabric has become the material of choice for flexible oil tanks, water storage bags, and heavy-duty outdoor protective equipment. In oilfield logistics and aviation ground support, the fabric offers a lightweight, durable alternative for liquid storage and transport, with excellent oil resistance, airtight sealing, and low-temperature toughness (withstanding temperatures as low as -60°C). Compared to traditional rubber or rigid containers, it significantly reduces weight and folds compactly for easy storage. In emergency response and military supply scenarios, its tear resistance and high-frequency welding compatibility enable rapid deployment and reliable performance under harsh field conditions. Jinlong is driven by a deep understanding of material science to continuously refine our products-ensuring every meter of fabric delivers strength you can count on.
Features of Polyester TPU Fabric
•High-strength Reinforced Structure: Polyester base fabric offers superior tensile and tear strength, fixing pure TPU film's weaknesses of low strength and stretch deformation.
•Excellent Air & Water Tightness: Functional TPU layer provides reliable sealing and waterproof performance for liquid storage, transportation and harsh outdoor applications.
•All-weather Weather Resistance: Stays flexible without hardening or cracking at low temperatures. Optional anti-UV formula prevents sunlight aging, suitable for open-air sites with sharp temperature changes.
•Optimized Hydrolysis Resistance: Improved formula reduces hydrolysis of polyester substrates under hot-humid conditions. It maintains stable air tightness and mechanical properties under long-term liquid storage and water immersion.
•Eco-friendly Versatile Substrate: Non-toxic and eco-safe. Ideal for flexible tanks, flood barriers, aquaculture liners and inflatable equipment in engineering, aquaculture and emergency industries.
•Multi-process Thermal Weldability: Supports glue-free hot air & high-frequency welding for firm seams. Advanced lamination avoids yellowing and strengthens fabric-film adhesion, resisting delamination after immersion and folding.
