Everyone has a love for beauty. No matter whether your car is a new car or has been used for a long time, you want it to look clean. So now many people begin to make Jinan invisible car clothes for their cars. However, the traditional waxing, glaring, coating and crystal plating are unable to cope with the car scratch, and the paint that should fall off will still fall off.

不过当时的隐形车衣和现在的隐形车衣有着本质上的不同，因为当时所谓的“隐形车衣”其实就是一层塑料膜，和现在PVC材质的隐形车衣很相似，它们较大优点就是硬度很高，贴在汽车表面能够依靠坚硬的物理性质保护漆面，但这一类产品的弊端也是显而易见的。它们的使用寿命很短。

However, the invisibility car clothing at that time is essentially different from the invisibility car clothing now, because the so-called "invisibility car clothing" at that time is actually a layer of plastic film, which is very similar to the PVC material invisibility car clothing now. Their greater advantage is that their hardness is very high. Sticking on the car surface can rely on the hard physical properties to protect the paint surface, but the disadvantages of this kind of products are also obvious. They have a short service life.

TPU是一种优良的材料，其化学性质和物理性质十分稳定而且耐磨性能十分强大，较天然橡胶耐磨五倍以上，是耐磨制品的材料之一，拉伸强度更是高达70MPa断裂伸长率可达1000%，正是因为这些强大的性质，TPU材质的隐形车衣能应对常见的刮伤甚是轻微的碰撞，而且事后只要车膜没有破裂，就能在很短时间里复原。

TPU is an excellent material. Its chemical and physical properties are very stable, and its wear resistance is very strong. It is more than five times more wear-resistant than natural rubber. It is one of the materials of wear-resistant products. Its tensile strength is as high as 70MPa, and its elongation at break can reach 1000%. It is precisely because of these strong properties that TPU invisible car clothing can cope with common scratches or even slight collisions, And afterwards, as long as the car film is not broken, it can recover in a very short time.

优良的隐形车衣在防止汽车被划伤方面可是一绝。当一个TPU材质的隐形车衣受到外力作用，发生破裂，外力撤销，这种TPU分子就会发生裂变伸长，当然，高温在相应程度上能促进或加快这种作用的发生，从而达到自愈的作用，我们买车花费的钱有10%是花在漆面上。

Good invisibility car clothing is the best way to prevent the car from being scratched. When a TPU stealth car coat is cracked and withdrawn by external force, the TPU molecule will undergo fission and elongation. Of course, high temperature can promote or accelerate the occurrence of this effect to a certain extent, so as to achieve self-healing effect. 10% of the money we spend on car purchase is spent on paint.
