Chitec Technology, a leading manufacturer of specialty chemicals, today announced a major technical milestone. Its flagship product for Thermoplastic Polyurethane (TPU) applications, Chiguard® R-455, has received a Notice of Allowance for Invention Patent from the China National Intellectual Property Administration (CNIPA) (Application No.: 202211423110.X). This follows the successful patent grant on November 11, 2024. These consecutive patent achievements not only validate the innovative formulation of R-455 but also establish a robust technical barrier and a strong market moat in China, the world's largest market for automotive and optical films.
R-455: A Revolutionary Solution to "Migration" and "Yellowing" in TPU Films
The continuous patent certifications for Chiguard® R-455 mark Chitec Technology's success in overcoming the long-standing technical bottleneck of balancing "Weatherability" and "Transparency" in TPU materials. The core technology focuses on breaking the loading limits of traditional UV absorbers through an innovative "Polymer Structure" design. Chiguard® R-455 offers the following key advantages:
- Reactive Locking Technology, Zero Migration Risk:
R-455 forms a stable chemical bond with the TPU matrix, precisely "locking" the UV absorber onto the polymer chain. Even at high loading levels of 10% to 20%, there is absolutely no risk of traditional additive migration (blooming), completely resolving concerns about surface haze. - Superior Optical Performance, High Transparency Protection:
Patent data shows that with an R-455 loading of 10-20%, the light-shielding layer not only provides excellent UV protection but also maintains a visible light transmittance of over 65%. This characteristic perfectly meets the stringent transparency and aesthetic requirements of high-end optical films and Paint Protection Films (PPF).
Targeting High-Growth Sectors: Deepening Presence in PPF and Optical Electronics Markets
With China's New Energy Vehicle (NEV) market leading the world and the increasing demand for weather-resistant materials in consumer electronics, the market potential for R-455 is highly promising. Chitec Technology notes that this patent secures 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 external displays and touch panel films, ensuring long-term optical clarity.
- Green Energy & Outdoor Construction Materials: Suitable for solar backsheets and vehicle exteriors, withstanding extreme weather conditions.
Comprehensive Patent Portfolio Strengthening Competitiveness:
As demand for high-quality weather-resistant materials surges in China and globally, Chiguard® R-455 is expected to further expand its market share, backed by its complete patent protection and superior performance. Chitec Technology remains committed to deep cultivation in the specialty chemicals field, creating maximum value for customers through technical innovation.
