According to the evolution of invisible car clothing substrate, TPU car clothing film production line manufacturers can be roughly divided into three types: PU, PVC, and TPU. In fact, there is another type of invisible car clothing substrate on the market, which is synonymous with the Chinese market and is only one word away from TPU - TPH. So, what is TPH, and what are its connections and differences from TPU?

What is TPH?

The manufacturer of TPU car clothing film production line stated that TPH is also known as modified polymer. In fact, it is adding a softening plasticizer (modified molecule) to PVC to make it softer. It can be understood as an improved version of PVC, mainly originating from Japan and South Korea. As mentioned earlier, the toughness and durability of second-generation PVC based car clothing are poor. TPH seems to have overcome the difficulty in stretching PVC, but core issues such as yellowing and cracking have not been improved. The manufacturer generally provides a warranty of about 3 years.

2. Relationship between TPH, PVC, and TPU:

At best, TPH is an upgraded version of PVC, but its essence is still the same. However, in actual promotion, due to the only word difference between "TPH" and "TPU", many merchants selling TPH car clothing will advertise that their quality is comparable, in order to confuse the audience and increase the price of TPH material invisible car clothing. Actually, there is a significant difference between the two.

3. Differences between TPH and TPU:

The manufacturer of TPU car clothing film production line stated that compared to TPH, TPH materials containing invisible car clothing have weak impermeability, poor durability, low toughness, and shorter service life. Moreover, the disadvantage of TPH is that over time, plasticizers that soften can easily precipitate into the topcoat layer, resulting in the problem of glue loss and retention. On the other hand, TPU materials containing invisible car vests often have higher impermeability, hydrophobicity, durability, and toughness, and their yellowing resistance time and lifespan are also longer.

So overall, the substrate of TPU is more advanced and of higher quality. Although the price is relatively high, it is better than TPH stealth car vests in other aspects, with fewer after-sales issues, making it a good choice for mid to high-end car owners with sufficient funds.
