For paint protection film, long-term clarity is just as important as scratch resistance and self-healing performance.
In high-UV regions such as the Middle East, Southeast Asia, Southern US and Australia, continuous exposure to intense sunlight can accelerate yellowing in lower-grade PPF. For distributors, installers and automotive film brands, this can affect the appearance of the film and ultimately customer satisfaction.

That is why CNGfilm uses optical-grade aliphatic TPU across its clear and color PPF ranges, providing a stable material foundation for long-term UV resistance and color clarity.
Yellowing is closely related to the chemical structure of the TPU used in the film.

Compared with aliphatic TPU, aromatic TPU is generally more susceptible to UV-induced degradation. Prolonged exposure to sunlight can gradually affect the optical appearance of the film, resulting in yellowing and reduced clarity.
For automotive PPF used in hot and UV-intensive climates, selecting the right TPU is therefore an important part of product development.
CNGfilm develops TPU materials through in-house polymer research and formulation development.

Our material structure is designed to improve resistance to UV-related oxidation and help maintain film clarity during long-term outdoor exposure.
Aliphatic TPU PPF offers several advantages for automotive applications:
High optical clarity
Improved UV resistance
Better resistance to yellowing
Stable color appearance
Flexible film performance
Formulations can also be adjusted according to different climate and application requirements, helping distributors develop products suited to their local markets.
Material selection is only part of achieving stable PPF performance. Laboratory testing and production control are equally important.
CNGfilm conducts accelerated weathering tests to evaluate film performance under prolonged UV and environmental exposure. These tests help assess changes in appearance, clarity and color stability over time.
For B2B customers, weathering test reports can be provided to support product validation and local marketing claims.
CNGfilm manufactures anti-yellow PPF through automated production processes with controlled film thickness and coating parameters.
Different product grades can be developed with customized specifications, including:
7.5 mil | 8.5 mil | 10 mil
This allows distributors and automotive film brands to build different product tiers, from entry-level solutions to premium PPF ranges.
Customized acrylic adhesive systems are also available according to installation requirements, including options designed for clean removal and compatibility with different OEM paint finishes.
For distributors and brand owners operating in hot and high-UV markets, choosing the right TPU can make a significant difference to the long-term appearance of PPF.

With aliphatic TPU materials, in-house formulation development, accelerated weathering testing and controlled production, CNGfilm provides a foundation for developing UV resistant paint protection film for global automotive markets.
