octyl p-methoxycinnamate：The best plastic anti-aging agent Plastics processing, storage and usage，as the polymer molecules by environmental factors (mainly ultraviolet radiation), provoking molecular strand breaks, weight reduction and changes in molecular structure or chemical changes that reduce the physical and mechanical properties of plastics, or even lose value. This change usually called plastic degradation or aging effect. In daily life we often see plastic film aging in the sun exposure for a long time will occur after aging plastic color, thin, brittle or even disappear, etc. It is a manifestation of aging plastic. Plastic can be fragments or powder according to the degree of aging. If this type of plastic itself is non-toxic, so aging is harmless to human .such as polyethylene, polypropylene, etc. Some plastic molding added in the harmful additives (lead-based stabilizer), aging is harmful to human, such as some PVC products. Some people have a test in Shandong, Hebei, Liaoning, Jilin, Heilongjiang and other areas of performance plastic windows; the main purpose is to observe the natural state of the aging of the plastic window color case. There are more plastic profile manufacturer in these regions, and application are more common. The survey showed that, the vast majority of plastic profiles for 3 years in age began, with up to 5 years of aging will be very serious. In order to prevent plastic from aging,people added some of the antioxidantin in the plastic molding process , light stabilizer, heat stabilizer additives to plastics to delay or inhibit oxidation and degradation. Currently, the plastic anti-aging agent is used frequently lead salt products. However, these formulations used in the lead salts and sulfides produces a black lead sulfide material in the air easy to cause black spots on the surface profile, accelerate the aging of plastic, thus forming a cycle is difficult to reconcile the contradictions. In order to overcome the traditiona....
