What is TPU films?

TPU films, also known as thermoplastic polyurethane films, are a type of flexible plastic film made from thermoplastic polyurethane resin. TPU is a versatile material that combines the properties of rubber and plastic, resulting in a film that offers excellent flexibility, strength, and durability.

TPU films have several key characteristics and properties:

1. Flexibility and Elasticity: TPU films are highly flexible and exhibit elastic behavior. They can be easily stretched, bent, or compressed without losing their shape or integrity. TPU films have a memory effect, allowing them to recover their original shape after deformation, making them ideal for applications that require flexibility and resilience.

2. Strength and Tear Resistance: TPU films offer high tensile strength and tear resistance. They can withstand considerable stretching, pulling, or impact forces without tearing or breaking. This property ensures the durability and long-lasting performance of TPU films.

3. Abrasion Resistance: TPU films have good resistance to abrasion and wear. They can withstand friction and contact with rough surfaces without easily deteriorating or developing signs of wear and tear. This makes TPU films suitable for applications that require protection against abrasion or where frequent contact with abrasive materials is expected.

4. Moisture Resistance: TPU films have inherent moisture resistance. They act as a barrier against water and moisture, preventing their passage. This property makes TPU films suitable for applications where protection against moisture or humidity is essential.

5. Chemical Resistance: TPU films exhibit resistance to many chemicals, including oils, greases, solvents, and mild acids and bases. They are less prone to degradation or damage when exposed to these substances, making them suitable for applications that involve contact with chemicals.

6. Transparent and Colorable: TPU films can be produced with varying levels of transparency, ranging from transparent to translucent or opaque, depending on the specific formulation. They can also be easily pigmented or dyed, allowing for a wide range of color options.

7. Processability: TPU films can be easily processed and fabricated using various techniques such as heat sealing, welding, adhesive bonding, or sewing. They can be laminated or coated onto other materials to provide additional properties or functionalities.

TPU films find applications in diverse industries, including footwear, apparel, electronics, automotive, sports and leisure, medical, and industrial sectors. They are used for products such as sportswear, outdoor gear, protective films, inflatable products, medical devices, flexible electronics, and more.

It's worth noting that TPU films can be formulated with different additives or reinforcements to enhance specific properties such as flame resistance, UV resistance, antimicrobial properties, or increased stiffness. Customization of TPU films allows them to meet the specific requirements of various applications.
