TPU film: introduction and application of new elastic materials
1. Introduction to TPU film
TPU, the full name of Thermoplastic Polyurethanes, is a new elastic material made by extrusion and mixing of MDI containing NCO functional groups, POLYOL and 1.4BG containing OH functional groups. It combines the elasticity of rubber and the processability of plastic, and has good elasticity, physical properties and various mechanical strengths.
2. TPU film production process
TPU film is a film made from TPU granules through processes such as calendering, casting, film blowing, and coating. This production process gives the TPU film excellent physical properties and wide applicability.
3. Main characteristics of TPU film
Good elasticity: TPU film has good elasticity and can maintain stable performance in various environments.
Good physical properties: Its physical properties are superior, including wear resistance, tear resistance and chemical resistance.
High mechanical strength: TPU film has high mechanical strength and can withstand large pressure and tension.
4. Application fields of TPU film
Clothing and textiles: TPU films can be used to make clothing and textiles with windproof, dustproof and UV protection functions.
Packaging industry: In the packaging industry, TPU films are often used to make adhesive tapes, packaging films, air cushion films, etc., providing good protection effects.
Medical devices: Due to the biocompatibility and chemical resistance of TPU film, it is widely used in the manufacture of medical supplies and medical devices, such as medical dressings, catheters, infusion bags, and artificial joints.
Smart wear and new energy fields: With the development of technology, TPU films are also used in the manufacturing of smart wearable devices, such as smart watch straps and cases; at the same time, in the field of new energy, such as solar panels and wind power blades In the protection,TPU film also plays an important role.
5. Market prospects
With the development of the global economy and the increase in people's demand for high-performance materials, the market prospects of TPU films are broad. It is expected that in the next few years, the market size of TPU film will continue to expand and be used in more fields.
