Product introduction

Dragonsorb®-791 is a synergistic mixture of oligomeric hindered amine light stabilizers (a mixture of light stabilizers 770 and 944). Application fields include PP, PP / EPDM and PP / PE / EPDM mixture (TPO class). Dragonsorb®-791 is an excellent light stabilizer for thick products, such as car bumpers, dashboard, garden tables and chairs, etc. The synergistic effect between the high molecular weight and low molecular weight hindered amine light stabilizer components in Dragonsorb®-791 maximizes the protection of the polymer from degradation due to UV radiation and long-term heating.
