Qu'est-ce que la Lumière Stabilisateur-944 CAS 70624-18-9？

UV-944, aussi connu comme la lumière stabilisatrice HS-944, est blanche à jaune clair, les particules de poudre ou de, le point de fusion 100-135°C, poids moléculaire 2000-3100, avec une excellente compatibilité, l'extraction de la résistance et de la faible volatilité. Depuis UV-944 est un de haute masse moléculaire relative, stabilisateur, et la molécule ne contient qu'une grande quantité de méthyler, il est stable lorsqu'ils sont traités avec chaud de l'oxygène.

UV 944 (CAS 70624-18-9), also known as Chimassorb 944 or UV Absorber 944, is a high-performance hindered amine light stabilizer (HALS) widely used in plastics, coatings, and polymer materials to protect against UV-induced degradation.

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.

Applications

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.
