- Chemical Family
- Hindered Amine Light Stabilizer (HALS)
Dragonsorb® 770 is a hindered amine light stabilizer used for anti-photooxidation aging of polyethylene, polypropylene, and polystyrene products. It also has a good effect on ABS resin, polyurethane, polyester, and other plastics. This product provides good light stability on plastic moldings, even when used in small quantities. When working with antioxidants, it improves heat resistance, and when mixed with other UV absorbers, it provides greater UV resistance.
