Light stabilizer FENTASTAB 770
Light stabilizer is a compound added to polymer materials. Its main function is to resist the aging and degradation of materials caused by ultraviolet radiation and other light conditions. The mechanism of action of light stabilizer mainly includes the following aspects:
Absorbing UV rays: Light stabilizers absorb UV radiation and prevent it from directly hitting the polymer surface. This helps to reduce direct damage to polymer materials caused by UV rays.
Photolysis reaction: Light stabilizers can convert ultraviolet energy into heat energy through photolysis reaction, thereby reducing the damage of ultraviolet rays to materials. This reaction allows light energy to be effectively converted and slows down the aging of polymer materials.
Free radical capture: The chemicals in light stabilizers have the ability to capture free radicals. Free radicals are generated by UV radiation and are the main factor that causes polymer materials to age. By capturing free radicals, light stabilizers can prevent them from damaging the polymer structure.
Energy transfer: Light stabilizers can also transfer ultraviolet energy to light stabilizer molecules through the energy transfer mechanism, causing them to become excited, thereby slowing down the aging process of polymer materials.
FENTASTAB 770, di(2,2,6,6-tetramethyl-4-piperidinyl) sebacate. Among the first batch of hindered amine light stabilizer products in the world born in the 1970s, 770 is still widely used in the contemporary plastics industry. The annual consumption of 770 in China accounts for about 20% of the total consumption of hindered amine light stabilizers.
