The advantages of Plastic antioxidantsadmin
Plastic antioxidants has been widely used in plastics. Among these,polyolefin, ABS is used the most, followed by POM, PVC and nylon. When use them, two or more antioxidants should be take into consideration, thus can produce advantages of additive, or synergistic effect, in order to obtain better results.
①Additive effects: when take primary antioxidant and secondary antioxidant into use,they play their own characteristics, which better than alone one. The use of a high concentration of antioxidants can cause side effects. But when taken out of several low concentrations antioxidants, thay can prevent the side effects, and can also play additive effects.
②Synergistic effect: When the antioxidant used appropriatly, their total performance can over the effectiveness of their respective single-use. It is be called synergistic effect
Finally, the stability of oxygen is different between the different plastic, so some plastics without adding antioxidants. While others must be added antioxidants, plastics antioxidant is used to capture the activity of free radicals, so that to interrupt the chain reaction. Which purpose is to delay the process of oxidation and plastic speed. Press the mechanism of action of antioxidants, it can affect on all plastics.
