The development of car clothing materials
The key to car clothing is the base film, so the development history of car clothing materials is the development history of the material of the base film, which has gone through the following stages.
- The first generation -- PU material
PU material, the world's first 3M rhino skin in 1966, used for the people in 2004, mainly used in the main engine factory, door buckle, side skirt, bottom of the rear leaf, front and rear bars corner and other positions.
- Second generation - PVC material
PVC material, PU in the early manufacturing is difficult to break the height of 1.52 meters, and PVO material can be easily done, and thin and easy to stretch, but the shortcomings are also as obvious as PU, scratches, discoloration, yellowing, oxidation and so on.
- The third generation -- TPU material
TPU material. The world's first 1.52 meters high TPU for the United States XPEL in 2009 developed, TPU substrate advantages in dry thermoplastic polyamide elastomer rubber, with scratch automatic reduction, soft stretching known! The disadvantages and PU the same, yellow flowers, discoloration and other problems.
- The fourth generation - TPU+ coating
TPU+ coating. The world's first for the United States XPEL in 2011 research and development and creation, 2.5MIL thickness of the industry all the history of paint protective film, the later brands are in 0.5MIL coating. Cannot surpass XPEL. It is more resistant to yellowing, oxidation and corrosion.
- At present, the mainstream substrate - a new generation of TPU, second reduction technology
New generation TPU, second recovery technology. At present, many brands on the market use Japanese substrates, because the price of raw materials in the United States is high. It breaks through the traditional TPU must be coated technology (a TPU coating, a PU coating) the cost is greatly reduced, the surface coating particles are small, the density of the strong can make TPU scratches at room temperature instant reduction.
Although the expensive substrate, there is a threshold of the mounting process, so that the price of car clothing is still high, but with the continuous improvement of paint protective film products, all aspects of maturity, paint protective film is becoming the market needs, and the vigorous development of new energy vehicles, but also speed up the consumer's awareness of car protection ideas, car clothing can take advantage of the trend, expand the market share, As standard on new cars as window film.
