Common applications include electronic devices, automotive components, displays, and industrial equipment.

2. Membranes and Liners: TPU films can be employed as membranes and liners in different industries. They exhibit excellent chemical resistance and can act as barriers against moisture, gases, and liquids. TPU films are commonly used in applications such as water and fuel tanks, inflatable structures, medical packaging, and industrial containment systems.

3. Apparel and Textiles: TPU films are commonly used in the apparel and textile industry. They can be applied as coatings or laminates to fabrics to enhance properties like water resistance, breathability, and durability. TPU films are often used in rainwear, sportswear, footwear, and outdoor gear to provide protection against the elements.

4. Medical Devices: TPU films find applications in the medical field due to their biocompatibility and flexibility. They can be used as coatings or components of medical devices, such as catheters, wound dressings, and surgical drapes. TPU films provide a smooth and non-irritating surface while offering desired properties like strength, flexibility, and resistance to bodily fluids.

5. Flexible Packaging: TPU films can be utilized in flexible packaging applications. They offer excellent sealability, moisture resistance, and puncture resistance. TPU films are commonly used as part of multilayer packaging structures for food, pharmaceuticals, and other perishable or sensitive products.

6. Laminates and Composites: TPU films can be employed as a component in laminates or composites to enhance properties like strength, flexibility, and impact resistance. They are often used in the aerospace, automotive, and construction industries to improve the performance and durability of various components and structures.

It's important to note that the specific use of 80 μm TPU film should consider the desired properties, industry standards, regulatory requirements, and manufacturer guidelines. Furthermore, customization options, such as surface treatments, adhesives, or color options, may be available to meet specific application requirements.

TPU (Thermoplastic Polyurethane) films are categorized based on their raw material aspect into two types: polyester-based TPU films and

PEUR films.

1. Polyester-based TPU films:

These films use polyesters as the soft segment, which provides the material with high tensile strength

and good abrasion resistance. These films are also known for their excellent resistance to oils, chemicals,

UV rays, and hydrolysis. They are commonly used in industrial, automotive, and apparel applications.

2. PEUR films:

These films use 'PE' as the soft segment, which provides the material with high flexibility and elasticity.

PEUR based films are also known for their excellent low-temperature flexibility, transparency, and water

vapor permeability. They are commonly used in medical, food packaging, and inflatable product applications.

Both polyester and PEUR films have their own unique properties that make them suitable for

different types of applications. It is essential to consider the specific performance and application requirements

when selecting the appropriate raw material aspect for TPU films.

Both Polyester type and PEUR (Thermoplastic Polyurethane) films have different properties

and are used for various applications. Here are some examples of applications in real-world scenarios:

Polyester Type TPU Film:

1. Apparel and textiles:

Polyester type TPU films are ideal for use in outdoor sportswear and other protective clothing applications

due to its excellent waterproof and breathability properties.

2. Flexible electronics:

Polyester type TPU films can be used for flexible electronics applications due to their excellent electrical insulation

and protection against mechanical damage.

3. Automotive industry:

Polyester type TPU films are used in the automotive industry for production of airbags, seat covers,

and door panel covers, as well as other parts that require excellent abrasion and chemical resistance.

4. Renewable energy:

Polyester type TPU films can be used in renewable energy applications for manufacturing of photovoltaic

films due to its excellent weather resistance and durability.

PEUR Type TPU Film:

1. Medical devices:

PEUR type TPU films are widely used in the medical industry for manufacturing of temporary or permanent implants,

catheters, and other medical devices. The material has excellent biocompatibility and can be sterilized using various methods.

2. Food industry:

PEUR type TPU films are used for food packaging applications due to its excellent water resistance properties.

3. Decorative films:

PEUR type TPU films can be used for production of decorative films and laminates due to its excellent clarity and gloss.

4. Sporting goods:

PEUR type TPU films are used in sporting goods for manufacturing of balls, rafts, and other inflatable products

due to its excellent flexibility and toughness.

The production process of thermoplastic urethane (TPU) film typically involves the following steps:

1. Raw material preparation:

The manufacturing process starts with the preparation of raw materials.

TPU film is made from a mixture of aliphatic or aromatic polyester or polyether diols, polyols, and diisocyanates.

2. Polymerization:

The raw materials are mixed together to form a polymer solution. TPU is created by reacting the diisocyanate with the diol,

producing a prepolymer. This prepolymer is then reacted with the polyol to create TPU.

3. Film extrusion:

The TPU polymer solution is fed into an extrusion machine, where it is heated under high pressure to create a molten mass.

The molten mass is then extruded through a die to create a continuous film of uniform thickness.

4. Film cooling and solidification:

The TPU film is then cooled, typically using a water bath, to solidify it and ensure that it maintains its shape.

5. Film treatment and finishing:

After the film has been cooled and solidified, it may be treated with a range of finishes, such as printing, lamination, or embossing.

6. Film inspection and quality control:

The final TPU film product is subjected to stringent quality control measures to ensure that it meets the required specifications.

This includes testing for thickness, tensile strength, elongation, and other physical properties.

7. Film packaging:

Finally, the TPU film is cut to the desired length and wound onto rolls. The rolls are then packaged and shipped to customers.

The production of TPU films involves a multi-stage process that requires careful control of temperature, pressure, and other variables to achieve high-quality films with consistent physical properties.
