Raw Material Selection: The main raw material for TPU film is thermoplastic polyurethane (TPU) granules. Suitable polyester polyols and diisocyanates are selected based on product performance requirements.

Formulation and Mixing: TPU granules are mixed uniformly with other additives such as antioxidants and UV absorbers in a specific ratio to meet specific performance requirements.

Suitable Temperature and Humidity: TPU film should be stored in an environment with a temperature of 10℃-30℃ and a relative humidity of 40%-60%. Excessive temperature intensifies molecular chain activity, causing the film to soften, stick together, and even chemically degrade; excessively low temperature causes it to harden and become brittle, reducing its flexibility. Excessive humidity easily absorbs water, triggering hydrolysis, leading to weakened tensile strength and reduced transparency; excessively low humidity causes the film to dry and become brittle.

TPU Transparent Film: Colorless and transparent, with a high light transmittance of over 90%, allowing clear visibility of object surfaces. Commonly used in scenarios where appearance needs to be displayed, such as mobile phone screen protectors and transparent packaging materials, protecting the product's appearance without affecting it.

TPU film is a thin film made of thermoplastic polyurethane material. It possesses excellent flexibility, abrasion resistance, and weather resistance, and is widely used in various fields. Below are some common applications:
