Is the Thicker the TPU PPF Film, the Better?

    

With the development of the times, almost every family has their own car, and the car detailing is becoming more and more popular. Nowadays, everyone is familiar with TPU PPF,because it is anti-resistance,yellowing-resistance. This star product has gradually flowed into ordinary people’s homes from a niche, and it has also been verified by time. When most car owners choose to install clear TPU PPF Film, they always feel that the thicker the car paint pritection film, the better the protection effect. Each car PPF film brand often has different thickness specifications, and the thicker the price, the higher. So is the thicker the car TPU PPF Film, the better? How thick is the appropriate thickness?

 

 

 

The Clear TPU PPF Film has a total of five layers, mainly composed of the top coating, the middle TPU substrate, and the bottom glue, of which the TPU substrate accounts for 70%, so the thickness of the car TPU PPF Film is mainly determined by the TPU substrate.

 

At present, the thickness of common TPU PPF Film on the market is roughly divided into the following specifications: 5.8MIL, 6.5MIL, 7.5MIL, 8.0MIL, 8.5MIL, 10MIL, and some factories now also produce 12MIL.

 

 It is difficult to distinguish  the thickness of car TPU PPF film for the naked eye.How to know the thickness of TPU PPF Film?This requires professional film measuring instruments to measure.

 

First of all, it is certain that “the thicker the car TPU PPF Film, the higher the protective performance”. It should be emphasized that the premise of this sentence is the same series of products of the same brand, or the materials, processes, production environment, and product quality of the TPU substrate, coating, glue, etc. are the same. Car TPU PPF films made of inferior materials have poor toughness and poor anti-scratch ability due to defects in the material itself, even if the TPU substrate is better. Different materials have different effects. Just like 2MIL thick paper and 1MIL thick steel plate, the steel plate is definitely more scratch-resistant.

 

 

 

The tensile strength of the TPU PPF Film is proportional to the thickness. Therefore, during construction, the thicker the car PPF film is, the more laborious it is to stretch, the worse the construction performance is, and it is more challenging for the film applicator. At the same time, as the thickness increases, the stiffness of the car TPU PPF film increases accordingly, and the ductility decreases. If a material with poor ductility is used, the corners are more likely to warp and debond over time. Therefore, the increase in thickness places higher requirements on the physical properties of the TPU substrate, and it is necessary to balance the elasticity, tensile strength, ductility, toughness and other aspects of performance.

 

If the TPU PPF Film is too thin, the protective performance will be reduced. If it is too thick, it will increase the difficulty of construction and the risk of warping and degumming. What thickness is the most suitable?

Based on the actual situation of the Car TPU PPF Film and the manufacturer’s test data, the characteristics of car TPU PPF films of various thicknesses are summarized as follows. You can refer to them when selecting:

 

6.0-7.0mil: The film is slightly thin, the protective performance is average, the price will more cheaper,so it is an entry-level economic product that covers a wider range of car models;

 

7.5mil: The mainstream model in the current market, it has been verified that its protective performance and construction performance are relatively balanced, and the price is relatively moderate;

 

Above 8.5mil: The film is thicker and has strong protective performance, but the construction requirements are higher; the matching requirements for the base film and glue are also higher. If the material is not selected properly, there may be risks such as degumming and warping in the later stage.
