TPU film: high performance and environmental protection and innovative materials
With the rapid development of science and technology, new materials are coming out in an endless stream, bringing constant power to the progress of the times. Among them, thermoplastic polyurethane (TPU) film has been widely used in many industries with unique properties, and is gradually becoming a bright star in the field of materials science.
First, the basic characteristics of TPU film
TPU film is made on the basis of TPU granule material, through calendering, casting, blown film, coating and other special processes. It has high strength and excellent elasticity, can withstand large external forces and quickly return to its original state, not easy to produce permanent deformation. In addition, TPU film also has the following significant characteristics:
Abrasion resistance: its surface hardness is moderate, excellent abrasion resistance, can maintain stability in harsh environments.
Temperature resistance: it can maintain stability in the temperature range of -40℃ to 120℃.
Chemical resistance: Due to the stability of the urethane bond in the molecular structure, TPU functional groups can resist corrosion by acids, alkalis and many organic solvents.
Moisture permeability: making it ideal for applications where breathability is required.
Anti-aging and UV resistance: able to maintain a stable appearance and characteristics in all types of outdoor use in the long term.
Second, the wide range of applications of TPU film
TPU film because of its unique properties, in a number of areas to show a broad application prospects:
Automotive field: TPU film can be used in the vehicle's interior and exterior decorative materials, such as seat materials, door trim panels, etc., to enhance the comfort and aesthetics of the vehicle. At the same time, it can also be used for automotive glass protection film to effectively protect the glass from scratches and impacts.
Electronic field: In electronic products, TPU film is often used as a flexible display panel, promoting the development of electronic products in the direction of thinner, lighter and softer. In addition, it can also be used for cell phone cases, tablet PC screen protection film and other protective products, effectively extending the service life of the equipment.
Medical field: TPU film is also widely used in the medical field, such as surgical instrument coatings, artificial heart valves, drug delivery systems. Its excellent compatibility and biodegradability make it an ideal material for making medical devices.
Sports: TPU film can be used to make casual shoes, sports bags and other fitness equipment, providing durability and comfort. Its high elasticity and abrasion resistance make it the material of choice for sports footwear.
Industrial: In the industrial sector, TPU films are used as conveyor belts, drum roll packaging, etc. Their abrasion and wear resistance ensures continuous and efficient operation of machinery and equipment.
