Product Description:

Characteristics and uses:

UV-622 is a polymeric hindered amine light stabilizer (HALS) with broad applicability that works effectively in a variety of polymers and applications. It is especially suitable for PE materials (including injection molding, rotational molding, film materials and tapes), EVA, PP fiber, polyurethane, polyacetal, elastomers, adhesives and seals, etc. UV-622 has good light stabilization effect on materials containing carbon black system.

The following are its main features:

1. No discoloration: It has excellent anti-discoloration performance and can maintain the original color of the material.

2. Low volatility and anti-migration: It has low volatility and is not easy to evaporate during use, thus reducing the risk of migration.

3. Weak alkalinity: It has weak alkalinity, which helps to reduce the interaction with fuel and other stabilizers and improve stability.

4. Widely applicable to food contact materials: The application range of UV-622 covers food contact materials and complies with relevant safety standards.

In addition, UV-622 has high molecular weight, low volatility, low degradation, good extraction resistance and fading resistance, and excellent thermal stability, and can be combined with Fsci@AO (antioxidant) and Fsci@UVA (ultraviolet absorption). agent) etc. Mainly used in materials such as polyethylene, polypropylene, polystyrene, olefin copolymers, polyester, soft PVC, polyurethane, trimerdehyde and polyamide.

The excellent performance of UV-622 makes it an indispensable additive in various plastic products, effectively improving the stability and weather resistance of the product and extending its service life.
