Can car ppf harden?

DATA: 2023-05 23

Com tots sabem,Pel·lícula PPFis a special plastic film used to protect cars-this has caused some misunderstandings for some people who don't know much:sostenidor de cotxe transparent will become harder and harder during use. This has fallen into the misunderstanding of solidified thinking. In fact, the weather resistance ofautomotive paint protection filmsof different materials is different.The better the weather resistance, the less likely it is to harden.


1.PU Polyurethane

Avantatges: strong toughness

Desavantatges: Poor weather resistance, scratches cannot be repaired, poor resistance to corrosion, yellowing over time


2.PVC Polyvinyl chloride

The most primitive base material of polyvinyl chloride is called PVC, which is polyvinyl chloride, and the cost of PVC is relatively low. This kind of film changes in this way. It was very bright at the beginning, and then after about two months, it began to stain or appear water spots. After about half a year, the film began to turn yellow and hard, and even cracks appeared on the film surface. Finally, the owner couldn't stand it anymore and began to tear the film. Terrible.

Avantatges: hard material, strong impact resistance, low cost

Desavantatges: can't carry out hemming treatment, degumming is serious, scratches cannot be repaired, and will gradually turn yellow


3.TPU Thermoplastic urethanes thermoplastic polyurethane

Avantatges: strong weather resistance, strong toughness, good stretchability, oil resistance, corrosion resistance and chemical resistance, recyclable, environmentally friendly

Desavantatges: complex production process, high manufacturing cost


4.The surface thermoplastic polyurethane launched by KPAL FILM

Avantatges: Coatings with different properties are developed on TPU, and different high-performance invisible car covers such as fast repair, corrosion resistance, yellowing resistance, and stain resistance can be customized according to different needs, and car covers with different visual effects can also be extended. TPU is a thermoplastic polyurethane elastomer. Divided into aromatic and aliphatic, aromatic yellowing, fast aging, aliphatic non-yellowing, slow aging.

Desavantatges: The production process is complicated, the yield rate is low, and the manufacturing cost is slightly more expensive.
