Something about PPF thickness

When it comes to PPF, the first thing that comes to mind is its anti-scratch function, and there are many videos on the Internet that resist scratches. Since it is to resist rubbing, many car owners feel that the thicker the car cover, the better it can withstand rubbing.

In fact, it is a misunderstanding that the thicker the car coat is, the better. Because the premise of the realization of various functions of the PPF is that the master is well attached to the surface of the car paint, and itr is too thick, which is not conducive to the construction. Therefore, it is generally recommended that the thickness be 6-10mil, not more than 10mil.

Of course, the thickness is comparable only when the quality of substrate and nano-coating is excellent.

If you want to choose the right PPF at a reasonable price, you must choose the right Paint protection film supplier. For example, KPAL K series of the film , the same TPU material and nano-coating, within the appropriate range,

the thicker the thickness, the more resistant to scratches and

repairs. The better the performance of scratches etc.

The higher the elongation at break and the degree of elongation of the ppf, the higher the toughness, which can better adapt to various paint radians and is easy to apply; this kind of toughness can help buffer the impact of external forces and prevent the car paint from being scratched and scratched. hurt.

At the same time, PPF is resistant to high and low temperature and can be used in various environments, even in the extremely cold regions. The stronger the high temperature resistance, the higher the yellowing resistance, which also promotes the function of thermal repair of scratches.

The thickness of the PPF is actually the sum of the thicknesses of the three main structural layers of self-healing coating + TPU substrate layer + glue layer, that is, the thickness of the material in the above chart, which is also the actual thickness (in fact, it is actually attached to the car The paint surface is only these three layers), generally between 6-10mil.

However, in practice, due to the different production batches of products, there will be an error of ±0.5mil~±1.0mil in the thickness of the official announcement by the brand (the industry standard allows the thickness error to be within 1mil).

The difference in the thickness of the paint protection film is mainly the difference in the thickness of the nano-coating. The nano-coating determines the self-healing effect of scratches. As long as the nano-coating is not penetrated, the film can repair itself. Therefore, under normal circumstances, the thicker the ppf is, the better its scratch resistance, corrosion resistance and scratch self-healing function.

Of course, this thickness should be kept within a certain range, neither too thick nor too thin. If the coating is too thin, it is easy to be damaged, so it cannot protect it well. If it is too thick, it is inconvenient for the construction of the invisible car cover, and the wrapping is also easy to warp.
