What is TPU Film?
Definition and Overview
Thermoplastic polyurethane (TPU) film is a type of plastic that combines the best properties of both rubber and plastic. It is known for its durability, elasticity, and transparency. TPU film can be processed using a variety of techniques, including extrusion, injection molding, and blow molding, making it suitable for numerous applications.
Historical Development
TPU was first developed in the 1950s by the German chemical company Bayer AG. Since then, it has evolved significantly, with improvements in its chemical structure and processing methods, leading to a wide range of applications in various industries.
Technical Specifications
Composition and Properties
TPU is composed of linear segmented block copolymers, which include hard and soft segments. The ratio of these segments can be adjusted to alter the film's hardness, elasticity, and other properties. TPU films exhibit excellent mechanical properties, including high tensile strength and elongation at break.
Variants and Grades
TPU films come in various grades, depending on their hardness, elasticity, and specific application requirements. Common grades include polyester-based TPU, polyether-based TPU, and polycaprolactone-based TPU, each offering different levels of abrasion resistance, hydrolysis resistance, and low-temperature performance.
