What is TPU Film?
Definition of TPU
Thermoplastic Polyurethane (TPU) is a highly versatile polymer, known for its flexibility, durability, and resistance to abrasion, oil, and grease. It is a type of polyurethane that exhibits a thermoplastic behavior, meaning it can be heated and reshaped without changing its properties permanently. TPU films, derived from TPU sheets, are thin, flexible materials widely used in various industries, from electronics to fashion.
Composition of TPU Films
TPU films are created from a blend of polyether or polyester-based TPU resins, which determine their final properties such as transparency, flexibility, and resistance to environmental factors. Depending on the desired application, TPU films can be customized with various additives to improve performance, including UV stabilizers, colorants, or flame retardants.
Advantages of TPU Films
