What Is The Difference Between Polyether TPU Film And Polyester TPU?

Understanding TPU Film and Its Material Variations

Thermoplastic polyurethane (TPU) film is a versatile material known for its elasticity, waterproofness, breathability, and excellent tear resistance. Depending on the molecular structure of its soft segment, TPU can be categorized into two main types: polyether TPU film and polyester TPU film. Both share a similar base chemistry but perform differently under varying environmental and mechanical conditions. Recognizing these differences helps manufacturers select the right material for their product’s intended use.

Structural Differences Between Polyether and Polyester TPU

The main distinction lies in the type of polyol used during polymerization. Polyether TPU is synthesized using polyether polyols, while polyester TPU is made from polyester polyols. This structural difference directly affects the film’s resistance to hydrolysis, chemical stability, and mechanical strength.

Applications and Material Selection

Each TPU type serves different performance goals. Choosing between polyether and polyester TPU film depends on the product’s environmental exposure, temperature range, and mechanical requirements. Polyether TPU excels in wet, cold, or humid environments, while polyester TPU is favored for applications requiring durability, stiffness, and oil resistance.

• Polyether TPU film is commonly used in ski gloves, cold-resistant gloves, waterproof textiles, sports equipment, and medical devices.
• Polyester TPU film finds extensive use in industrial belts, automotive interiors, and protective covers that demand tensile strength and thermal stability.

Manufacturing and Quality Control

Our TPU films are produced using advanced German machinery and carefully selected raw materials sourced domestically and internationally. The available film thickness ranges from 0.007mm to 2.0mm, and the width is adjustable between 0.5m and 3.4m. All films undergo SGS testing to guarantee consistent performance and safety. With ten production lines and a monthly output of approximately 800 tons, we provide stable supply and fast delivery to our clients, serving as a trusted supplier for 80% of composite material factories in the home textile industry.

Choosing the Right TPU Film for Your Application

When selecting between polyether and polyester TPU film, consider environmental factors first. For applications exposed to moisture, cold temperatures, or continuous bending, polyether TPU offers better durability and flexibility. For high-temperature or oil-contact environments, polyester TPU delivers superior performance and longevity. Understanding the specific mechanical and environmental demands of your product will help ensure optimal performance and lifespan.
