Alfa Chemistry: Light Stabilizers Make A Debut for the Plastics & Rubber Industries
Photodegradation may lead to undesirable changes in the properties of plastics and rubbers , such as tensile strength, color , or shape. Therefore, light stabilizers are added to extend the life cycle and improve the appearance of polymers. Earlier this month, Alfa Chemistry announced the launch of varieties of light stabilizers , a kind of additives that are uniquely developed to minimize or prevent the damage to polymers caused by exposure to the environmental parameters of light, heat , and air. The degradation damage caused by UV radiation include s : color fading, deterioration of mechanical properties, and the formation of visible defects such as cracks. A ccording to different mechanism s of action, l ight stabilizers can be divided into the following categories: the l ight screener, UV absorber, q uencher as well as f ree radical scavenger . “ As derivatives of 2,2,6,6-tetramethylpiperidine, hindered amine light stabilizers (...
