From a professional point of view, stealth car clothing is currently made of several materials, such as PVC, TPH and TPU.
PVC: It is the earliest material of invisible car clothes on the market, that is, polyvinyl chloride, which is regarded as the first generation of invisible car clothes. Needless to say, it is mainly protected by hardness, which is seriously yellowed and is not recommended.
TPH: the material is between PVC and TPU. Compared with PVC, it has better yellowing resistance, but it is much worse than TPU in scratch repair.
TPU: At present, the best car clothing material, the scientific name is thermoplastic polyurethane elastomer rubber, which has excellent toughness, can be softened at a certain temperature, has good ductility, is easy to construct and can be pasted repeatedly.
Second, the taste.
Feel through smell. If you smell a strong chemical smell, it means that the raw materials used in the car clothes are inferior. A good protective film for automobile paint should be tasteless or irritating.
Third, brightness.
A good film attached to the paint surface will improve the brightness, especially for black car paint.
Fourth, pollution prevention.
In order to simulate the dirt on the car body surface in daily use, such as oil stain, oxidation, acid rain, ink, bird droppings, sewage and so on. We used an oily marker that is difficult to clean to test the covered and uncovered covers respectively, and the covered marker can be wiped clean with a paper towel. If it is a film with poor performance, it can't achieve this effect.
Verb (short for verb) biting.
A good film has good wear resistance and durability. If you choose bad materials, you can't install them perfectly, protect your car and seriously reduce the value of your car.
Six, hydrophobicity
Double-coated TPU (thermoplastic polyurethane elastomer rubber) is made of three layers, which has good smoothness and is not easy to remain liquid, thus avoiding the worry that parking cars outdoors in rainy days will be polluted by liquid such as acid rain.
Seven, cover up the original scratches of car paint.
Vehicles that have been used for a period of time, especially those with black or dark paint, will definitely have many obvious dazzling lines on the hood. However, after the painted protective film is pasted, the difference between uncoated and coated vehicles is obvious, the obvious wear marks before are completely covered, and the whole body is completely new.
