Zhejiang Newcastle - Newsweek｜Issue 2: PVC, TPH & TPU — How to Choose the Right Car Paint Protection Film?

Hello, this is the editor from Newcastle. Today, let's talk about how to judge and choose among the wide variety of car wrap materials available on the market.

To avoid making a bad choice, we first need to understand the essential differences between these three materials. Although PVC, TPH and TPU all appear to be plastic films, they are actually products of different generations with vastly different performance. They can even be regarded as outdated, transitional and mainstream options respectively.

PVC was the earliest material used in car paint protection films, essentially the common plastic film we see daily. Its only core advantage is its low cost. However, it has fatal drawbacks: it is hard and brittle, with extremely poor flexibility and stretchability. During installation, it requires heating for shaping, and adhesion promoters must be used on highly curved body parts. After prolonged exposure to sunlight, it easily yellows, embrittles and cracks rapidly, which not only affects appearance but may also leave adhesive residue during removal, or even stick to and damage the original factory paint. Today, apart from some vehicle color change films still using PVC, it has been basically eliminated from the formal paint protection film market.

TPH is an improved version launched by manufacturers to compensate for the shortcomings of PVC. Essentially still a PVC-based material, it only adds plasticizers to enhance flexibility. It is slightly more expensive than PVC, and its only advantage is that it conforms to body curves more easily than PVC during installation. However, it does not overcome the inherent defects of PVC: its weather resistance is still insufficient, and problems such as delamination, fading and cracking tend to occur after 2–3 years of use. It offers limited protection, with weak impact and scratch resistance, and basically no self-healing function.

TPU is recognized as the "golden material" in the current car paint protection film industry. As a third-generation paint protection film, it is also widely acknowledged as the optimal choice in the industry. Its core advantages stem from its stable molecular structure, providing exceptional toughness, elasticity and weather resistance, as well as scratch self-healing properties. High-quality aliphatic TPU car paint protection films can last for 5 to 10 years.

If you own a new car, a luxury vehicle, or plan to keep your car for the long term, and genuinely want to protect the original factory paint and improve vehicle resale value, TPU is the only best solution. This is especially true for car owners who frequently drive on highways, park outdoors long-term, or live in areas with frequent tree branch scratches, bird droppings and tree sap corrosion. The impact resistance, corrosion resistance and self-healing capabilities of TPU effectively address these core pain points.

Our factory-direct TPU car paint protection films are made from high-grade domestic masterbatches, delivering stable and reliable quality with excellent heat-induced self-healing performance. By eliminating intermediate distribution channels, we offer a significant cost-performance advantage. We welcome inquiries and cooperation from all customers.
