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 stabilizers mainly includes the following aspects:


UV Absorption: Light stabilizers absorb UV radiation and prevent it from directly hitting the polymer surface. This helps mitigate direct UV damage to polymer materials.


Photolysis reaction: Light stabilizers can convert ultraviolet energy into heat energy through photolysis reaction, thereby reducing ultraviolet damage to materials. This reaction effectively converts light energy and slows down the aging rate of polymer materials.


Free radical trapping: The chemicals in light stabilizers have the ability to trap free radicals. UV irradiation generates free radicals, which are the main factors that cause the aging of polymer materials. By trapping free radicals, light stabilizers prevent them from damaging the polymer structure.


Energy transfer: Light stabilizers can also transfer ultraviolet energy to light stabilizer molecules through energy transfer mechanisms, causing them to enter an excited state, thereby slowing down the aging process of polymer materials.


FENTASTAB 770, bis(2,2,6,6-tetramethyl-4-piperidinyl) sebacate. Among the world's first batch of hindered amine light stabilizer products born in the 1970s, 770 is a hindered amine product that is still widely used in the contemporary plastics industry. The annual domestic consumption of 770 accounts for 1% of the total consumption of hindered amine light stabilizers. Around 20%.
