DERFLEX TPU Coated Nylon Fabric
Waterproof, airtight, flexible and weldable nylon composite material for professional outdoor, inflatable and industrial OEM programs.
What Is TPU Coated Nylon?
TPU coated nylon is a technical composite fabric made by bonding thermoplastic polyurethane to a nylon textile base. The nylon layer provides strength, tear resistance and lightweight reinforcement, while TPU creates the waterproof, airtight, flexible and weldable surface.
Built for Products That Must Hold Air, Block Water or Survive Repeated Folding
Unlike basic waterproof fabric, TPU coated nylon is selected when the final product needs reliable welded seams, air retention, abrasion resistance, cold flexibility and a premium soft-touch material direction. This is why it is widely used in packrafts, inflatable kayaks, dry bags, waterproof backpacks, air mattresses, medical air cells, flexible bladders and rescue gear.
DERFLEX focuses on B2B specification development instead of only selling standard fabric rolls. Buyers can discuss denier, TPU chemistry, coating thickness, surface finish, color, roll width, welding method, pressure requirement and repeat-order consistency before bulk production.
TPU Coated Nylon Structure
- Outer TPU Layer: waterproof barrier, abrasion surface and weldable coating.
- Nylon Base Fabric: ripstop, plain weave, Nylon 6, Nylon 66 or high-tenacity nylon reinforcement.
- Optional Inner TPU Layer: sealing surface for double-side welding, baffles, patches and airtight structures.
- Functional Options: anti-UV, hydrolysis-resistant, flame-retardant, antimicrobial, low-temperature or high-pressure grades.
TPU Coated Nylon Fabric Options from DERFLEX
From ultralight inflatable gear to rugged marine and rescue products, DERFLEX can develop TPU nylon material according to final product weight, pressure, welding method and durability target.
