TPU film: waterproof and oil-proof magical protective film
First, let's discuss the basic characteristics of TPU film.
Material Nature
TPU (thermoplastic polyurethane elastomer) is a mature, environmentally friendly material with advantages such as high tension, high tensile strength, strong toughness, and aging resistance. These characteristics underpin its water- and oil-repellent properties. From a molecular perspective, TPU's structure enables it to block both water and oil molecules.
Physical Properties
TPU film boasts high strength and excellent toughness. This high strength and toughness ensures that the film maintains its integrity when formed into a protective film, making it resistant to scratches and tears, thus providing a physical barrier against water and oil.
Second, let's discuss the water-repellent performance of TPU film.
Practical Application Examples
In the field of tabletop protective films, many TPU tablecloths and tabletop protective films are advertised as waterproof. For example, food-grade TPU table mats and transparent, soft glass tablecloths effectively prevent water penetration. Even if water stains occur on the table, they won't penetrate the surface, protecting it from water erosion.
As for kitchen stove protective films, products such as TPU film and hydrogel films are used to prevent water splashes on stoves, keeping them dry and clean.
Principle Analysis
The molecular structure of TPU film is relatively tight, and it is difficult for water molecules to penetrate. At the same time, it has characteristics such as high tension, which enables the film to maintain a stable structure when it comes into contact with water, and will not deform due to water pressure and cause water to penetrate.
Third, the performance of TPU film in oil resistance.
Practical application case
Take the table protective film as an example, TPU table mats can effectively prevent the pollution and penetration of oil stains. TPU film can play a good isolation role and is easy to clean, whether it is food oil stains on the table or oil stains on the kitchen console.
In some industrial fields, if TPU film protective film is used to protect equipment, it can also prevent oil substances from eroding and contaminating the surface of the equipment.
Principle Analysis
The size and properties of oil molecules are different from those of water molecules, but TPU film can also prevent the diffusion and penetration of oil molecules because it has a dense molecular structure and special chemical properties. Moreover, the oil resistance of TPU film [4] also contributes to its oil resistance.
IV. Conclusion
In general, TPU film protective film performs well in terms of water and oil resistance. It has great application potential in the protection of household items and industrial equipment in daily life. With the continuous development of technology, the waterproof and oil-proof properties of TPU film protective film may be further improved, thus playing an important role in more fields.
