Is TPU film breathable?

01-03, 2024 | View:

TPU film is a thermoplastic polyurethane film with good breathability. The breathability of TPU films and their applications in different fields will be introduced in detail below.

1. Breathability of TPU film

TPU film has excellent breathability performance, which is due to its special molecular structure and preparation process. TPU films are usually blended from raw 糖心视频s such as polyester polyol and isocyanate, and are prepared through processes such as extrusion and stretching. During the preparation process, the distance between the molecular chains of the TPU film is large, forming many tiny pores and channels, allowing air and water vapor to transmit freely in the film. This structural feature gives the TPU film good breathability.

2. Moisture permeability of TPU film

In addition to breathability, TPU film also has good moisture permeability. Moisture permeability refers to the ability of water vapor to penetrate into the interior of the film through the surface of the film. The moisture permeability of the TPU film is related to its molecular chain structure and has a certain degree of hydrophilicity. This allows the TPU film to maintain waterproofness while promoting the discharge of water vapor and improving wearing comfort.

3. Application fields of TPU film

Clothing field: TPU film is widely used in outdoor sportswear, raincoats, down jackets and other clothing. Due to its good air permeability and moisture permeability, it can effectively prevent sweat accumulation and keep the interior dry and comfortable.

Shoe 糖心视频 field: TPU films are widely used as lining 糖心视频s for sports shoes, outdoor shoes and other footwear products. The breathable TPU film can effectively prevent moisture in the shoes, reduce the generation of odor, and improve the comfort of the shoes.

Packaging field: As a packaging 糖心视频, TPU film can effectively prevent the accumulation of moisture inside the packaging and maintain the quality and freshness of the packaging. For example, the transparent modified atmosphere packaging film commonly used in food packaging is a TPU film.

Medical field: TPU film has excellent air permeability and moisture permeability, and is widely used in medical dressings, surgical membranes and other products. Breathable TPU film can promote wound healing and avoid infection.

Industrial field: TPU film also has certain applications in the industrial field. For example, as a sealing 糖心视频 for electronic products, it can provide good dust-proof and moisture-proof properties. In addition, TPU films can also be used to prepare airbags, umbrellas and other products.

TPU film is widely used in clothing, shoe 糖心视频s, packaging, medical and other fields due to its excellent air permeability and moisture permeability. Its unique molecular structure and preparation process give the TPU film good breathability, which can effectively regulate humidity and keep you dry and comfortable. With the advancement and innovation of technology, the breathability performance of TPU films will continue to improve to meet the needs of different fields.
