what is light stabilizer
Light stabilizers are a group of polymer additives that protect polymers from degradation due to light, heat and the sun's ultraviolet rays. While these three factors naturally cause polymers to crack, break or discolor, light stabilizers strengthen polymers to resist the degrading effects of these factors.
Thanks to light stabilizers, your car's mirrors and bumpers won't crack and break weeks after you buy the car. Your tires won't rip every now and then, and your pipes won't chalk after months of use.
Types of Light Stabilizers
Remember when we said that light stabilizers are a group of polymer additives? This group, then, includes three polymer additives. they are:
UV absorber
quenching agent, and
Hindered Photoamine Stabilizers (HALS).
UV absorbers, quenchers, and HALS all help prevent polymer degradation, but they each do their job differently. These light stabilizers also have different expiration dates, different fields of application, and vary in price. The remainder of this article will explore each of these light stabilizers in depth.
