隐形车衣的自行修复能力是其卖点之一，贴膜后的车辆小刮擦时可以自行恢复。但是这个自行修复是有前提的。

One of its selling points is the self-healing ability of the invisible car clothing. After the film is applied, the car can recover itself when it is scratched. But there is a prerequisite for this self-healing.

1、材质-tpu

1. Material - TPU

具有划痕修复的是采用TPU材质的隐形车衣才有的功能。TPU，英文：Thermoplastic polyurethanes，名称是：热塑性聚氨酯弹性体橡胶。这种材料有一个特性，就是弹性特别好，裂变伸长率大于50%，是一种外力撤除后复原性非常好的高分子材料。

The function of scratch repair is only available for the invisible car coat made of TPU. TPU, English: thermoplastic polyurethanes, the name is: thermoplastic polyurethane elastomer rubber. This material has a characteristic, that is, it is particularly elastic, and the fission elongation is greater than 50%. It is a polymer material with very good recovery after the external force is removed.

TPU隐形车衣划痕自愈的原理如下：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，高温在一定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。

The principle of scratch self-healing of TPU stealth car coat is as follows: when a TPU stealth car coat is cracked by external force, and the external force is withdrawn, this TPU molecule will undergo fission and elongation.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.

2、温度-常温/高温

2. Temperature - normal / high temperature

常温通常指摄氏温度23℃，在此温度下能实现自修复功能的只有第五代TPU隐形车衣（汽车漆面保护膜），虽然有人测试过第五代TPU隐形车衣即时在0℃也有缓慢的自修复功能，但也没有见其宣称过低温自修复。

Normal temperature usually refers to the temperature of 23 ° C. at this temperature, only the fifth generation TPU stealth car clothing (automobile paint protection film) can realize self-healing function. Although some people have tested that the fifth generation TPU stealth car clothing can also have slow self-healing function even at 0 ° C, they have not claimed low-temperature self-healing.

由于技术的壁垒，目前市面上主要的还是第四代TPU隐形车衣，其实现自修复功能的温度需要60~85℃之间，过高会破坏修复涂层因子，大家知道炎热的夏天，暴晒的车体温度远远超过60℃，反正不用担心修复温度，所以很多隐形车衣借机大肆宣传自己的拥有常温自修复功能。

Due to technical barriers, the fourth generation TPU stealth car clothing is still the main one in the market. The temperature for self-healing function needs to be between 60 and 85 ℃, and too high will damage the repair coating factor. As we all know, in hot summer, the temperature of the exposed car body is far higher than 60 ℃. Anyway, there is no need to worry about the repair temperature. Therefore, many brands of stealth car clothing take the opportunity to vigorously publicize that their brands have normal temperature self-healing function.

所以说，使用TPU材质的第五代隐形车衣，在常温或者高温下自行修复能力良好。

Therefore, the fifth generation stealth car clothing made of TPU material has good self repairing ability at normal temperature or high temperature.
