Key Features

1. Excellent light stabilization effect: UV-944 can effectively protect polymer materials from ultraviolet light exposure and photodegradation and thermal degradation caused by long-term thermal aging. Its light stabilization effect far exceeds that of ultraviolet absorbers and nickel-containing stabilizers, especially in pigment systems where the effect is more obvious.

2. Good compatibility and processing performance: It is a light yellow transparent granular material with low volatility. It has good compatibility with various polymer materials such as PP, LDPE, HDPE, and PVC. It can be easily dispersed in the polymer matrix without affecting the transparency and color of the resin, and has excellent processing performance.

3. Wide application range and safe and reliable: UV-944 is suitable for various forms of materials such as films, fibers, and thick products, and can be used for multiple polymers including polyolefins, polyurethanes, and polyamides. Meanwhile, it has been approved by the FDA and can be used in food contact applications, demonstrating a certain level of safety.

应用程序

• Plastics: Protects films, sheets, and molded products from UV aging.

• Coatings and Paints: Enhances color retention and durability under sunlight.

• Polymer Materials: Applied in industrial polymers to extend service life and performance.
