TPU (Thermoplastic Polyurethane) drop stitch fabric is a high-performance material used in inflatable structures requiring rigidity, durability, and airtightness. Unlike PVC drop stitch, TPU offers superior flexibility, eco-friendliness, and resistance to UV/abrasion, making it ideal for premium inflatable products.
🔹 Applications of TPU Drop Stitch Fabric:
✔ Inflatable Stand-Up Paddleboards (SUPs) – High rigidity, lightweight.
✔ Rigid Inflatable Boats (RIBs) – Marine-grade durability.
✔ Inflatable Docks & Platforms – Stable floating surfaces.
✔ Aerospace & Military Inflatables – Crash-resistant air structures.
✔ Inflatable Tents & Shelters – Weatherproof, rigid walls.
