Overview of TPU film composite leather fabric
TPU film composite leather fabric is a high-performance material that combines thermoplastic polyurethane (TPU) films with natural or synthetic leather. This composite material not only inherits the advantages of TPU film and leather, but also optimizes in many aspects, making it have significant application advantages in military equipment.
TPU film, as a polymer material, has excellent wear resistance and chemical corrosion resistance. It can maintain good mechanical properties in extreme environments and is easy to process and mold, suitable for designs in various complex shapes. Leather is known for its soft, breathable and comfortable touch, providing an excellent wearing experience. Combining the two can meet the requirements of high-strength protection and comfort at the same time.
According to the research of the famous foreign document “Advanced Materials for Military Applications”, TPU film composite leather fabric not only performs excellent physical performance, but also improves the combat effectiveness of soldiers to a certain extent. For example, among the new tactical vests used by the US Special Forces, TPU film composite leather fabrics are widely used, and their excellent tear resistance and waterproof and breathable properties greatly enhance the durability and reliability of the equipment.
In addition, TPU film composite leather fabric also has environmentally friendly properties. Compared with traditional synthetic fibers, TPU materials are recyclable and reduce their environmental impact. This feature also meets the requirements of modern military equipment for sustainable development. Therefore, more and more countries are beginning to pay attention to and promote the use of such materials.
In order to more comprehensively understand the specific parameters of TPU film composite leather fabric and its performance in different application scenarios, we will introduce its main performance indicators and application cases in detail. By citing more authoritative foreign materials, we will further explore the advantages of this material in practical applications.

These parameters show that TPU film composite leather fabrics not only perform well in mechanical properties, but also maintain stable performance under extreme environmental conditions. For example, its excellent wear resistance and low moisture transmittance make this material very suitable for making military equipment that requires long-term exposure. At the same time, the flame retardant level reaches the UL94 V-0 standard, which means it can be extinguished quickly when it encounters a fire source, ensuring the safety of the user.
Main Performance Indicators
The main performance indicators of TPU film composite leather fabric include the following aspects:
-
Abrasion Resistance: TPU film composite leather fabric has extremely high wear resistance and can withstand long-term friction without easy damage. This makes it an ideal choice for manufacturing high-frequency contact areas such as military boots and gloves.
-
Chemical corrosion resistance: TPU materials themselves have strong chemical corrosion resistance, and after composite treatment, their chemical resistance is further improved. It can withstand common acid and alkali solutions and oil pollution, ensuring that the equipment can still work properly in harsh environments.
-
Tear resistance strength: According to the ASTM D2261 test method, the tear resistance strength of TPU film composite leather fabric can reach more than 100N. This means that even when pulled by external forces, the material is not prone to breaking, providing soldiers with reliable protection.
-
Waterproof and breathable: Through a special lamination process, a microporous structure is formed between the TPU film and the leather, which not only ensures that moisture cannot penetrate, but also effectively discharges internal moisture. This unique design makes the wearer feel dry in humid environmentsComfortable.
-
Low Temperature Toughness: TPU film composite leather fabric can still maintain good flexibility and elasticity in low temperature environments, and will not become brittle due to sudden temperature drops. This is especially important for soldiers fighting in cold areas, as traditional leather may lose its elasticity, resulting in inconvenience in wearing and even affecting mobility efficiency.
-
Fire retardant performance: As mentioned earlier, this material meets the UL94 V-0 flame retardant standard, which can instantly cut off the flame propagation path and reduce fire risk. This feature is particularly critical on the battlefield, especially when facing the threat of explosives, which can protect the lives of soldiers to the greatest extent.
-
Anti-bacterial and anti-mold: TPU film composite leather fabric contains antibacterial ingredients, which can inhibit bacteria and mold growth and reduce odor generation. This will help maintain personal hygiene and improve morale for troops stationed in the field for a long time.
To sum up, TPU film composite leather fabric has shown great application potential in the field of military equipment with its outstanding physical and chemical properties and functional characteristics. Next, we will further explore the application examples of this material in specific equipment, in order to more intuitively demonstrate its unique value.
