How to remove TPU film bubbles?

TPU film is a kind of polyurethane elastomer elastic rubber raw material with excellent comprehensive physical properties, which is widely used in textile, plastic film, rubber and other fields. In the process of TPU film application, there are often bubble problems, which harm the appearance and quality of the product. This paper will explain and respond to the characteristics and uses of TPU film from three aspects, the reason of bubble formation and the method of eliminating bubbles.

First, the properties and main uses of TPU film

TPU film is a new type of polymer material new environmental protection material, in the middle of rubber and plastic, with the following advantages:

Good toughness: TPU film has good elasticity and can be pulled several times without deformation.

Good process performance: TPU film has excellent process performance, including high mechanical strength, wear resistance, acid and alkali resistance, moisture resistance and so on.

Better processing performance: TPU film can be reprocessed by injection, extrusion, die casting and other commonly used thermoplastic processing technology.

Good clarity: TPU film can be processed as a protective film to maintain good clarity.

Good environmental maintenance: TPU film is a new type of environmental protection material in line with ecological environmental protection standards.

TPU film has a wide range of applications, including the scope of industrial fields and civil necessities, mainly including the following aspects:

Clothes and shoes: TPU membrane can be made into clothing fabric shoes with waterproof fabric functionality, providing better breathability and comfort. For example, jackets made of TPU film can maintain air permeability and ambient humidity, while ensuring warmth, wind resistance and water resistance.

Medical machinery: TPU film has a good compatibility and is suitable for the packaging protective layer of medical devices.

Fitness equipment: TPU film can be used to make fitness equipment sanitary napkins, knee pads, and accessories, with good wear resistance and wear resistance characteristics.

Automotive industry: TPU film can be used to make car driving seats, car interiors, hydraulic seals and other parts, with good wear resistance and aging resistance.

Construction industry: TPU membrane can process waterproof fabric raw materials, used for roof, wall, villa basement and other parts of the moisture treatment.

Fashion sports furniture: TPU film can be used to make inflatable products, swimming rings, inflatable cushions and other goods, with better durability and wear resistance.

The above are only some common main uses of TPU film, with the development of science and technology and the development and design of new materials, TPU film will be widely used in more fields.
