Jinlong TPU Drop Stitch Fabric is a premium double-wall inflatable material. Vertical polyester threads firmly connect the upper and lower TPU layers, engineered for high-performance inflatable products pursuing lightweight properties. Compared with conventional PVC drop stitch fabric, the TPU version achieves a 20%–40% weight reduction at equal strength. The finished products are easy to carry and store, ideal for weight-sensitive items such as water sports equipment and outdoor gear.

Its exclusive drop stitch structure ensures excellent flatness and rigidity after inflation, preventing sagging under load. Multiple core heights of 5cm, 10cm, 15cm, 20cm and 30cm are available to meet demands of various inflatable products. Treated with UV-resistant and wear-resistant coating, the fabric maintains consistent performance during long-term outdoor service.

Compared with PVC drop stitch fabric, Jinlong TPU drop stitch fabric boasts superior low-temperature flexibility and great hydrolysis resistance without harsh plastic odour. It features reliable interlayer adhesion and will not delaminate after repeated inflation, deflation and folding. It works reliably in freshwater, seawater and low-temperature outdoor environments. Compatible with high-frequency heat sealing and hot air welding, it forms airtight seams and facilitates large-scale industrial production. Jinlong offers all-round customization on thickness, colour and base fabric specifications to deliver stable and reliable material solutions for your product upgrades.

FAQ of TPU Drop Stitch Fabric

Q: What is TPU Drop Stitch Fabric?

A: It is a premium composite material made of high-tenacity polyester base fabric and TPU films bonded through thermal lamination. The dense drop stitch construction provides exceptional rigidity after inflation, while the TPU coating delivers superior eco-friendliness, flexibility, and air retention.

Q: What are the advantages of TPU drop stitch fabric over traditional PVC drop stitch?

A: TPU drop stitch is lighter, softer, and contains no plasticizers-eco-friendly and non-toxic. Unlike PVC, it does not become hard or brittle in low temperatures, resists creasing after folding, and packs down to a smaller volume for easy storage.

Q: What is the difference between Polyether-type and Polyester-type TPU drop stitch?

A: Polyether-type TPU offers excellent hydrolysis resistance, anti-microbial properties, and low-temperature performance, ideal for prolonged water contact (e.g., SUP boards, water storage bags). Polyester-type TPU delivers higher tensile strength, abrasion resistance, oil resistance, and heat resistance, suitable for industrial applications and fuel containers.

Q: What pressure can TPU drop stitch fabric withstand?

A: Standard TPU drop stitch fabric is rated for a working pressure of approximately 15 PSI, with a maximum burst pressure up to 30 PSI (depending on base fabric density and TPU thickness). This ensures finished products (such as paddle boards and floating docks) maintain a flat, rigid surface comparable to hard boards.

Q: Is the TPU drop stitch fabric material suitable for direct skin contact?

A: Absolutely. TPU is inherently non-toxic, odorless, and free from harmful chemicals, meeting multiple safety certifications. It is widely used in medical anti-bedsore mattresses, premium yoga mats, and inflatable gymnastics mats-all applications requiring skin-friendly, safe materials.

Q: What processing methods does TPU drop stitch fabric support?

A: It is fully compatible with high-frequency (RF) welding and thermal lamination. Through high temperature and pressure, TPU melts and bonds securely with the base fabric or another TPU layer, creating fully airtight, leak-proof seams-without the need for chemical adhesives.

Q: How does it perform in terms of folding durability and aging resistance?

A: TPU drop stitch fabric offers excellent fold endurance, resisting cracking or delamination after repeated folding and storage. High-quality TPU coatings provide outstanding UV resistance and abrasion resistance, significantly extending product service life in harsh outdoor environments.

Q: Can TPU drop stitch fabric be customized in specifications and appearance?

A: Yes. Jinlong offers full customization including color, weight, thickness, surface finish, and other treatments to meet diverse product requirements.
