TPU Fabrics: Advanced Materials for High-Performance Industrial, Medical, Military, and Food-Grade Applications
What is TPU Fabric?
Thermoplastic polyurethane (TPU) is a high-performance polymer known for its unique balance of elasticity, strength, and resistance to wear. Unlike rigid plastics, TPU behaves more like a hybrid between rubber and engineering plastic, combining flexibility with excellent toughness. It is inherently resistant to abrasion, puncture, and chemicals, and it remains elastic even at low temperatures.
Unlike PVC, TPU does not require harmful plasticizers to remain flexible, and it emits very little smoke during welding, making it a healthier choice for production environments. Compared with traditional PU, TPU offers greater durability, better hydrolysis resistance, and a broader service temperature range. These qualities make TPU fabrics especially suited for technical textiles where both mechanical performance and environmental safety are critical.
Today, TPU has become a core material for applications requiring waterproofing, airtightness, tear resistance, and long service life. From outdoor equipment to medical devices and industrial storage systems, TPU fabrics represent a new generation of sustainable performance textiles.

TPU Classification: Polyester vs Polyether
TPU fabrics are categorized based on their chemical backbone into polyester TPU and polyether TPU, each offering distinct advantages. This classification allows TPU fabrics to meet highly specialized requirements, including pressure resistance, bio-compatibility, and chemical safety
| Type | Chemical & Physical Properties | Typical Applications |
| Polyester TPU (Oleophilic) | High crystallinity, high tensile strength, abrasion-resistant, oil-resistant, moderate hydrolysis resistance | Oil storage tanks, chemical storage, industrial high-pressure applications |
| Polyether TPU (Hydrophilic) | Flexible, excellent hydrolysis resistance, antimicrobial, bio-compatible, high elasticity | Water storage tanks (food-grade), medical pads, wearable protective equipment |
| Blends / Custom Formulations | Tailored hydrophilicity or oleophilicity | Specialized tanks, membranes, hybrid applications |
High vs Low GSM TPU Fabrics
The gram weight (GSM) of TPU fabric significantly affects its performance and suitable applications:
Dejia use Nylon and Polyester basecloth to coat wtih TPU, Nylon is mainly for light weight fabric and Polyester more heavier fabric to give more strength.
| GSM | Characteristics | Typical Applications | Key differences |
| High GSM (Heavy-Duty) | Thick TPU coating, strong mechanical strength, high tensile strength, excellent abrasion resistance | Oxygen chambers, industrial tanks, water and oil storage, outdoor high-pressure containment | Designed for structural stability, airtightness, and durability under pressure. |
| Low GSM (Lightweight) | Thin TPU coating, soft and flexible, breathable, anti-bacterial | Medical pads, mattress covers, protective medical bags, wearable medical textiles | Prioritizes comfort, flexibility, and hygiene, while maintaining essential protective properties. |
