The difference between TPU paint protection film and TPH paint protection film

1. What is car paint protection film?

Paint protection film, also known as invisible car cover, English full name: Paint Protection Film (referred to as PPF), simply put, it is a transparent protective film attached to the paint surface of the car, which is a new type of high-performance environmental protection film. It can also be called car body transparent film, car paint protection film, car protective film, automotive paint protection film etc.

Car paint protection film originated in Europe and America, and was originally called “rhino hide”. In the 1960s and 1970s, it was used as a military product in U.S. military helicopters and stealth fighters. It was not until the 1990s that it was gradually used in civilian use, and it was mostly used in top racing cars.

It really started as a car paint protection product in the early 21st century, when it was mainly used for luxury cars and European royal cars. Around the 1910s, paint protection films did not enter the Chinese market. But at that time, car paint protection film manufacturers were all abroad, and imported car paint protection films were extremely expensive. Generally, only luxury cars would consider applying car paint protection films.

2. What is TPU car paint protection film?

TPU is thermoplastic polyurethane elastomer, the abbreviation of Thermoplastic Urethane, and the Chinese name is thermoplastic polyurethane elastomer. TPU is a polymer material formed by co-reacting diisocyanate molecules such as diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI) with macromolecular polyols and low molecular polyols (chain extenders). TPU has excellent characteristics of high tension, high tensile strength, toughness and aging resistance, and is a mature environmental protection material. At present, TPU has been widely used in medical and health care, electronic appliances, industry and sports, etc. It has high strength, good toughness, wear resistance, cold resistance, oil resistance, water resistance, aging resistance, weather resistance and other characteristics unmatched by other plastic materials. At the same time, it has many excellent functions such as high waterproof and moisture permeability, windproof, cold proof, antibacterial, mildew proof, warm keeping, UV resistance and energy release.

The main advantages of TPU: high wear resistance, wide range of hardness, high mechanical strength, good processing performance, oil resistance, water resistance, mold resistance, good environmental protection and recycling.

Therefore, the car paint protection film made of TPU material has the characteristics of super toughness, scratch resistance, impact resistance, wear resistance, and non-yellowing. It excellently protects the high-wear areas of the car paint surface. It can isolate the paint from the air, effectively prevent acid rain, oxidation, and protect the paint for a long time; it also has the ability to prevent the collision and friction of gravel and resist ultraviolet radiation; it has good ductility, strong transparency, strong adaptability to curved surfaces, and does not affect the appearance of the car body at all. The life span is as long as 5-10 years. TPU car paint protection film has automatic repair function, TPU unique enhanced scratch automatic repair coating, no need to take any measures, as time goes by, scratches will automatically repair, so that the car is far away from fine scratches and the sun Spiral pattern. Good UV resistance, prevent long-term damage to the car paint; protect the gloss of the original car paint. Good adhesiveness, no edge opening, no cracking. Good pressure sensitive adhesive properties, can ensure any time to remove without leaving any adhesive residue. TPU is very suitable for long-term use of outdoor paint protection, construction is completed, no yellowing, no cracking, no warping.

3. What is TPH car paint protection film?

TPH, Chinese name (Tryptophan Hydroxylase) TPH English full name Throughput per Hour, is a tryptophan hydroxylase macromolecule composed of diphenylmethane diisocyanate (MDE), toluene diisocyanate (TDE) and macromolecular polyols Material. To put it simply, TPH is PVC with plasticizer added. It has to be admitted that the invisible car cover made of TPH is better than PVC, but its essence is still PVC after all.

The characteristics of TPH material, 360-degree stretch, no baking, short construction time, strong toughness, through the mechanical test of metal sharp objects, strong toughness, high transparency, strong weather resistance and other advantages.

The TPH currently on the market is actually an upgraded version of PVC. Although the improved version of TPH has enhanced flexibility, due to the material, car owners generally report that its protection ability is weak and the material is relatively brittle. At the same time, because the cost of TPH materials is relatively low, the service life is generally about three years.

4. The main difference between TPU paint protection film and TPH car paint protection film

4.1 From the perspective of the base material, most of the TPU car paint protection films choose Lubrizol base material, BASF base material and other foreign well-known imported base materials, and the glue uses Ashland glue from the United States.

4.2 From the perspective of service life, the service life of TUP car paint protection film can be up to 10 years, generally more than 5 years. The maximum service life of TPH car paint protection film is only 3 years.

4.3 From the perspective of product performance, TPU car paint protection film has ultra-high ductility, super toughness, scratch resistance, collision resistance, wear resistance, and anti-yellowing, while TPH car paint protection film has weak protection ability and brittle material. And easy to yellow.

4.4 From the perspective of application scope, TPU paint protection film is mostly used in high-end vehicles and luxury cars, while TPH paint protection film is mostly used in family nanny cars or cheap scooters.

At present, many foreign car paint protection film distributors and wholesalers mostly choose to import TPU car paint protection film produced by Anhui Noyark from China. Most of this kind of car paint protection film choose Lubrizol base material and BASF base material, it use American Ashland glue, and the service life is generally as long as 8-10 years.
