What is TPU fabric composite film?

TPU fabric composite film is a kind of film material formed by compounding TPU film with other materials through a specific process. TPU (thermoplastic polyurethane) is a material between rubber and plastic, which has excellent characteristics such as high tensileness, strength and aging resistance, and is considered to be a green and environmentally friendly material
characteristic
TPU fabric composite film has the following characteristics:
Excellent physical properties: through the combination with high-strength fibers, the tensile strength and tear strength can be significantly improved; Compounding with flexible materials improves flexibility and crease resistance
Good chemical stability: It can resist the attack of a variety of chemical substances, and is suitable for acid-alkali environment and high-temperature environment
Environmentally friendly and recyclable: As an environmentally friendly material, TPU also has good recyclability, and the waste composite film can be recycled and reused to reduce environmental pollution
Preparation process
The preparation process of TPU fabric composite film includes the following methods:
Melt blending method: different materials are mixed in a molten state and made into composite films through extrusion, calendering and other processes. This method is simple to operate, but it requires attention to compatibility and dispersion between materials
Solution blending method: dissolve different materials in an appropriate solvent, mix evenly and then make a composite film by evaporating the solvent, hot pressing and other steps. This method can obtain a more homogeneous composite structure, but attention needs to be paid to solvent selection and recovery
Lamination method: Different materials are made into films separately and laminated together by hot pressing, adhesives, etc. This method can achieve the composite of multi-layer structures, but it is necessary to pay attention to the bonding strength and peel resistance between the layers
Fields of application
TPU fabric composite film is widely used in many fields:
Packaging: Because of its good barrier performance and chemical corrosion resistance, it is widely used in the packaging of food, medicine, cosmetics and other products
Construction: used for waterproofing, heat insulation, decorative materials, etc., with good weather resistance and ultraviolet resistance
Sports equipment field: Because of its good elasticity and wear resistance, it is often used in the manufacture of basketball, football and other sports equipment skin materials
Automotive industry: used in automotive seals and medical catheters, etc., can withstand large mechanical stress and is not easy to break
