The Key to Exceptional TPU Product Quality: Revonox? U-5068L’s Excellent Initial Color and Thermal Yellowing Resistance

??Initial Color: The Primary Factor of Product Appearance

In the application of thermoplastic polyurethane (TPU) materials, color is a crucial factor that influences consumer purchasing decisions. Bright colors not only attract attention but also symbolize product quality. The value of maintaining a stable initial color is crucial in ensuring that TPU products consistently present a pristine, new appearance.

??How Does Appearance Color Affect the Market?

With increasing market competition, consumer demands for products are becoming higher. Color is not only about aesthetics but also represents brand image and product quality. In high-end markets, such as automotive films and electronic product casings, consistent and long-lasting color stability is essential. Revonox? U-5068L (U-5068L) is a heat stabilizer specifically designed for TPU, ensuring that TPU products maintain color stability even after multiple thermal processes or in high-temperature environments.

??Why Choose Revonox? U-5068L?

?? Initial Color Stability

U-5068L significantly inhibits yellowing (Yellow Index) during TPU synthesis, even in high-temperature environments of 200°C to 250°C required for twin-screw polyurethane synthesis, greatly reducing yellowing caused by reactions with moisture and oxygen.

Comparison of Initial Color Test Results:

• Heat Stabilizer A: Initial YI value of 2.8
• Heat Stabilizer B: Initial YI value of 2.2
• Revonox? U-5068L: Initial YI value of only 1.7

??Superior Anti-Yellowing Ability After 96 Hours of Thermal Aging Test

In a rigorous 120°C heat aging test for 96 hours, U-5068L exhibited the lowest ?E. This indicates that U-5068L's performance in inhibiting thermal yellowing of TPU is significantly ahead of market competitors, maintaining the color stability of TPU materials even under harsh conditions.

Advantages of Choosing a Low Initial Color:

1. Enhance Product Appearance and Target High-End Markets: Providing TPU materials with low initial color and excellent thermal stability ensures that products remain aesthetically pleasing, meeting the stringent requirements of high-end application markets such as automotive films and electronic product casings.
2. Increase Production Efficiency and Reduce Costs: By minimizing reprocessing and waste due to color issues, production costs are reduced, and efficiency and product competitiveness are improved.
