What is TPU fabric composite film

TPU fabric composite film‌ is a film material that combines TPU film with other materials through a specific process. TPU (thermoplastic polyurethane) is a material between rubber and plastic. It has excellent characteristics such as high tension, strength and aging resistance, and is considered a green and environmentally friendly material.

characteristic

TPU fabric composite film has the following characteristics:

‌Excellent physical properties‌: By combining with high-strength fibers, tensile strength and tear strength can be significantly improved; composite with flexible materials can improve flexibility and crease resistance‌

Good chemical stability: It can resist the erosion of a variety of chemical substances, suitable for acid and alkaline environments and high temperature environments

Environmentally friendly and recyclable: As an environmentally friendly material, its composite film also has good recyclability. The discarded composite film during use 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: Mix different materials in a melting state and make a composite film through extrusion, calendering and other processes. This method is simple to operate, but it is necessary to pay attention to the 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 uniform composite structure, but attention should be paid to the selection and recycling of solvents‌

Lamination method: After making different materials into thin films, they are laminated together by hot pressing, adhesive, etc. This method can realize the composite of multi-layer structures, but attention should be paid to the bonding strength and peel resistance between the layers‌

Application areas

TPU fabric composite film is widely used in many fields:

Packaging field: Because of its good barrier properties and chemical corrosion resistance, it is widely used in the packaging of food, medicine, cosmetics and other products.

Construction field‌: used for waterproofing, heat insulation, decorative materials, etc., with good weather resistance and UV resistance‌

Sports equipment field‌: Due to its good elasticity and wear resistance, it is often used to manufacture outer skin materials for sports equipment such as basketball and football.

‌Auto industry: used in automotive seals and medical conduits, etc., can withstand large mechanical stresses without easy breakage
