Chitec Technology: High-Efficiency UV Protection Solution Chiguard® R-455 Granted Chinese Invention Patent, Suitable for TPU Film Applications

December 10, 2025 - Chitec Technology, a leading specialty chemicals company, announced a significant technological milestone. Its flagship product for thermoplastic polyurethane (TPU) applications, Chiguard® R-455, has recently received a patent grant notification from the China National Intellectual Property Administration (Application No.: 202211423110.X), following its successful invention patent acquisition on November 11, 2024. The successive receipt of these important patents not only validates the innovativeness of R-455's formulation technology but also establishes a strong technological barrier for this revolutionary product in China, the world's largest automotive and optical film market, building a solid global market moat.

R-455: A Revolutionary Product Solving TPU Film 'Migration' and 'Yellowing' Pain Points
The consecutive patent certifications for Chiguard® R-455 signify that Chitec Technology has successfully overcome the long-standing technical bottleneck in polyurethane (TPU) materials where achieving both 'weather resistance' and 'transparency' was difficult. The core technology focuses on breaking through the addition limits of traditional UV absorbers. Through an innovative 'polymer structural design', Chiguard® R-455 possesses the following key advantages:

● Reactive Locking Technology, Zero Migration Risk:
R-455 can form stable chemical bonds with the TPU substrate, precisely 'locking' the UV absorber onto the polymer chain. Even at high addition levels of 10% to 20%, it completely eliminates the migration problem associated with traditional additives, thoroughly resolving concerns about surface hazing.

● Exceptional Optical Performance, High Transparency Protection:
Patent data shows that under conditions where the addition amount of R-455 is between 10-20%, the light-shielding layer using this technology not only possesses excellent UV protection but also proves capable of maintaining over 65% visible light transmittance. This characteristic perfectly meets the stringent requirements for transparency and aesthetic quality in high-end optical films and paint protection film (PPF).

Targeting High-Growth Sectors: Deepening Focus on PPF and Optical Electronics Markets
With China's new energy vehicle market continuing to lead globally and the increasing demand for weather-resistant materials in consumer electronics, the market potential for R-455 is highly promising. Chitec Technology points out that this patent ensures R-455's exclusive advantages in the following key application areas:

High-End Automotive Paint Protection Film (PPF): Provides top-tier protection that delays yellowing and prevents migration.
Optical Display Materials: Applied to the exterior of displays and touch panel films, ensuring long-term optical clarity.
Green Energy and Outdoor Building Materials: Suitable for solar backsheets and vehicle exteriors, resisting extreme climates.
Complete Patent Portfolio Strengthens Product Competitiveness
As demand for high-quality weather-resistant materials surges in both the Chinese and global markets, Chiguard® R-455, with its comprehensive patent protection and exceptional performance, is expected to further expand its market share. Chitec Technology will continue to deepen its focus in the specialty chemicals field, creating maximum value for customers through technological innovation.
