隐形车衣（汽车漆面保护膜）材质有PVC、PU、TPU等。PVC（Polyvinyl chloride)即聚氯乙烯材质。它材质硬，抗冲击能力好，价格低，但无法实现包边，易掉胶，不能抵抗划痕，使用年限短。一年内就会出现发黄、橘皮、开裂、发乌等现象，不能二次回收利用，污染环境。PU（英文Polyurethane的简称）即聚氨基甲酸酯，聚氨酯。与PVC材质薄膜相比，PU保护膜韧性有所增强，但它本身耐候性差，抵御碱性腐蚀力差，会逐渐黄变，划痕也无法修复。TPU（Thermoplastic polyurethanes）名称为热塑性聚氨酯弹性体橡胶，具有优异的耐磨性、耐臭氧性、强度高、弹性好，同时还具有良好的耐低温、耐油性、耐化学药品，划痕可修复等性能。TPU保护膜可回收加工利用，环保，但生产工艺复杂，成本高。
Invisible garments (automotive paint protective film) are made of PVC, PU, TPU and so on. PVC (Polyvinyl chloride) is the material of polyvinyl chloride. It has hard material, good impact resistance and low price, but it can not achieve edge wrapping, easy to drop glue, can not resist scratches, and has a short service life. Within a year, yellowing, orange peel, cracking, blanching and other phenomena will occur, which can not be recycled twice and pollute the environment. PU (short for Polyurethane) is polyurethane, polyurethane. Compared with PVC film, PU protective film has stronger toughness, but it has poor weather resistance, poor resistance to alkaline corrosion, will gradually yellowing, scratches can not be repaired. TPU (Thermoplastic polyurethanes) is named as thermoplastic polyurethane elastomer rubber. It has excellent wear resistance, ozone resistance, high strength and good elasticity. It also has good low temperature resistance, oil resistance, chemical resistance, scratch repairability and other properties. TPU protective film can be recycled, processed and used. It is environmentally friendly, but the production process is complex and the cost is high.
In addition, there are four kinds of traditional car paint cosmetology, the first is waxing, the second is glaze sealing, the third is coating/crystal plating, and the fourth is invisible car clothing. The traditional protective principle of paint surface maintenance (coating, crystal plating, etc.) is: molecule covering the surface of car paint to protect car paint; invisible car clothing is the body directly pasted with high brightness colorless transparent protective film, the protective effect of both is self-evident. Invisible garments can completely isolate the paint damage caused by the outside world, such as pebbles, acid rain, sand and so on.
High wear resistance can resist slight scratches or rubbing. Compared with crystal plating, it has the advantage of more comprehensive protection of car paint, one construction and lifelong benefit. In addition, the invisible garment provides perfect concealment protection for the car at the same time, but also makes the car more bright. Compared with the traditional waxing and glazing, the protective layer of transparent film has better protection effect and does not hurt the car paint, which can achieve long-term and lasting protection effect. After pasting the invisible garment (transparent film), the appearance of the car body will not change. It is difficult to find its existence with the naked eye. It only improves the brightness and gloss of the car paint, just like invisible guard, tightly adheres to the surface of the car paint to resist the corrosion of grease, rain and snow. Even if the car leaks in the sun for a long time, the car paint is not easy to yellowing and aging. It can be seen that invisible garments have become the most popular car lacquer cosmetology, but how to choose so many brands of invisible garments?
From the domestic point of view, the invisible garment market has not been in the ascendant for a long time, there are a group of competitors, but also fish eyes mixed beads. At present, some domestic garment brands have no international official website, no entity company, no global case, no foreign video, invisible image stores, no peripheral products, etc., but they are coated with a layer of overseas brand Phnom Penh, the quality is really not flattering! Brand can be gold-plated, but invisible garment quality? Three years, five years, maybe in a shorter time, these invisible garments will appear yellowing, discoloration, cracking and many other problems, and XPEL invisible garments are the only one on the market that can guarantee 10 years of automobile paint protection film (official website can be queried). Moreover, XPEL stealth garment is completely computer-controlled cutting, without manual knife, more accurate, special car! XPEL stealth garment adopts a new generation of coated TPU material, which is relatively expensive, but has excellent quality and protection performance. For those who are used to plating crystal on their car, XPEL stealth garments appear, which makes the maintenance of car paint more convenient and effective.
