1、 What are the materials of Jinan invisible car clothing?

拥有好的材料才能做出好的产品，现在市面上一般有PVC、TPH和TPU。

Only with good materials can we make good products. Now there are PVC, TPH and TPU on the market.

PVC

PVC

市面上传统的隐形车衣材料，就是我们常说的塑料，比如说硬水管就是PVC材质的，加工成隐形车衣材料后，结构依旧偏硬，美观和胶层是个问题，时间长了可能会对用车造成困扰，质量太差的会损坏车漆。使用寿命在几个月到一两年不等。

The traditional invisible car cover material on the market is what we often call plastic. For example, the hard water pipe is made of PVC material. After being processed into the invisible car cover material, the structure is still hard. The beauty and adhesive layer are problems. After a long time, it may cause trouble to the car. If the quality is too poor, the car paint will be damaged. The service life varies from a few months to a year or two.

TPH

TPH

在传统材质中添加了增塑剂，经过改良拥有了不错的柔韧性能，但由于材质的关系，使用过程中依旧偏脆，保护能力偏弱，同时TPH材质成本较低，选用的胶层容易脱落，会在漆面产生胶印或遗胶，使用寿命在两三年左右。

Plasticizer is added to the traditional material, and it has good flexibility after improvement. However, due to the material, it is still brittle and weak in protection. At the same time, the cost of TPH material is low, and the selected adhesive layer is easy to fall off, which will produce offset or residual glue on the paint surface, and the service life is about two or three years.

TPU

TPU

广受追捧的材质，是一种热可塑性聚氨酯，物理性能、化学稳定性，属于成熟的材料，良好的韧性和热修复功能，让它备受喜爱，是隐形车衣好的材料，使用寿命5-10年。

The widely sought after material is a kind of thermoplastic polyurethane with excellent physical properties and chemical stability. It is a mature environmental protection material with good toughness and thermal repair function, which makes it popular. It is a good material for invisible car clothing with a service life of 5-10 years.

二，济南隐形车衣的材质要学会辨别

2、 Jinan invisible car clothing material to learn to distinguish

胶层测试:用手指顶住膜，胶层露在外侧，在漆面上反复点击，检验粘连性是否下降、胶层是否会脱落，好的TPU材质一般配有好的胶层，可以反复以上操作50次不影响胶层性能。

Adhesive layer test: hold the film with your fingers, the adhesive layer is exposed on the outside, and repeatedly click on the paint surface to check whether the adhesion drops and whether the adhesive layer will fall off. Good TPU materials are generally equipped with good adhesive layer, which can be operated for more than 50 times without affecting the performance of the adhesive layer.

拉伸测试:TPU材质，很明显张开有韧性丝，有很好的韧性，可以还原，PVC的抗拉伸能力就很差了。

Tensile test: TPU material, it is obvious that it has tenacity wire, good tenacity, and can be reduced, so the tensile resistance of PVC is very poor.

拿火烧:PVC和TPH热稳定性差，火烧会有明显变色和异味，烧完呈灰状，TPU材质可以保持良好性能，短暂用火烧不会点燃，烧完粘稠状，也不会变色，甚还能还原。

Fire burning: PVC and TPH have poor thermal stability, obvious discoloration and peculiar smell after fire, and they are ash like after burning. TPU material can maintain good performance, and can not be ignited after burning for a short time, and will not discolor after burning viscous, and can even be reduced.

拿钥匙划:PVC很硬，不会自动修复，TPH偏薄，TPU韧性强，自己划一下肯定是会有感觉的。同时TPU还能划痕自愈，加热秒还原。

Take the key to draw: PVC is very hard, it will not repair automatically, TPH is thin, TPU is tough, you will feel it if you draw it yourself. At the same time, TPU can also heal the scratch and restore after heating for 2 seconds.

三：总结TPU隐形车衣凸显的优势：

3： The advantages of TPU stealth car suit are summarized

稳定的自动修复能力，表层独有的致密纳米涂层除了提供强大的抗腐蚀能力外，还能拥有更好的修复能力，在还原的时候不会吸入灰尘(市面上有些些材质吸灰严重，导致膜干涩无光)，可以长久保持膜的完好和光线亮洁。很好的不沾污性能，远离外物腐蚀，长时间不黄变、不开裂等，拥有5-10年的质保时间，售后相对更加完整。

Stable automatic repair ability. The unique dense nano coating on the surface not only provides strong corrosion resistance, but also has better repair ability. It will not inhale dust when reducing (some materials in the market absorb dust seriously, leading to dry and dull film), and can keep the film intact and bright for a long time. Good non staining performance, far away from external corrosion, no yellowing and cracking for a long time, with 5-10 years of warranty, the after-sales service is relatively more complete.

材质是隐形车衣优劣的基础，选择优良材质的隐形车衣，可以给爱车更为强大的防御能力，面对环境侵蚀、意外伤害可以多一种保障，同时没有损坏车漆的风险，享受无忧的愉悦旅程。

Material is the basis of the advantages and disadvantages of the invisible car clothing. Choosing the excellent material of the invisible car clothing can give your car more powerful defense ability. In the face of environmental erosion and accidental injury, you can have more protection. At the same time, there is no risk of damage to the car paint, and you can enjoy a carefree journey.
