Aliphatic TPU FilmsFunction

Aliphatic TPU film is a special type of polyurethane film with many unique properties and a wide range of applications. The following is a detailed introduction to aliphatic TPU films:

1. Structure and characteristics

Aliphatic TPU film is made from polyester ether polyol and aliphatic diisocyanate through polymerization reaction. This structure gives the aliphatic TPU film many excellent properties, including:

Weather resistance: Aliphatic TPU film has excellent weather resistance, can maintain stable performance under various climate conditions, and is not easily affected by factors such as ultraviolet rays, high temperature, moisture, etc.

Wear resistance: Due to its polyurethane structure, aliphatic TPU film has good wear resistance and is able to resist scratches and abrasions, protecting the covered surface from damage.

Flexibility: Aliphatic TPU film has high flexibility and elasticity, can adapt to the deformation of the surface of the covered object, and maintain good fit and sealing.

Transparency: Aliphatic TPU film has excellent transparency and can provide clear visual effects without affecting the appearance of the covered surface.

Chemical stability: Aliphatic TPU film has good stability to many chemical substances and can resist erosion by corrosive substances such as acids, alkalis, greases, and solvents.

2. Application areas

Aliphatic TPU films are widely used in various fields due to their excellent properties, including but not limited to:

Packaging industry: Used as food packaging film, pharmaceutical packaging film, etc., with good sealing and fresh-keeping properties.

Medical devices: Used as medical film materials, such as medical gloves, medical catheters, etc., with good wear resistance and biocompatibility.

Clothing and textiles: Used as waterproof breathable membranes, elastic clothing films, etc. to maintain the comfort and breathability of clothing.

Industrial applications: Used as industrial membrane materials, such as waterproof membranes, thermal insulation membranes, etc., with good weather resistance and chemical resistance.

Electronic products: Used as protective films for electronic products, touch screen protective films, etc., to provide excellent scratch resistance and antifouling properties.

3. Environmental protection

Aliphatic TPU films have low environmental impact during production and use, meeting the requirements of modern environmental awareness. Compared with traditional plastic materials, aliphatic TPU films are easier to recycle and reuse, reducing resource consumption and waste emissions.
