Introduction of antioxidant 2246 / antioxidant MBP
This product is an antioxidant used in plastic rubber products. It is one of the better varieties of phenolic antioxidants. It has excellent protection against thermal oxygen, weathering, flexing aging and resistance to variable metals. Suitable for light and colored rubber products. In the plastics industry, it has protective effects on heat aging and photoaging of chlorinated polyether, impact resistant PS, ABS resin, polymethyl ether and fiber resin. It is a hindered phenolic antioxidant.
Antioxidant 2246 is a general-purpose, highly resistant phenol-aldehyde antioxidant with a wide range of uses. It is non-polluting, non-toxic, non-staining, and has excellent protection against heat, oxygen and cracking. It is commonly used in white. Or in the color of rubber and plastic products (polyethylene, polypropylene, polyoxymethylene, ABS resin and chlorinated polyether, etc.), especially for the aging of rubber products under sunlight, the maximum protection efficiency, vulcanization and plasticity No effect, easy to disperse in water, easy to use. ]
The anti-oxidation and anti-aging properties of this product are superior. Compared with the antioxidants 264 (BHT, T501) of the same series of products, it can be found through comparison test that in the original antioxidant 264 (BHT, T501) formula, only use Antioxidant 264 (BHT, T501) one-third of the amount of antioxidant 2246 can achieve or exceed the effect of the original antioxidant 264 (BHT, T501). If used in combination with the UV absorber UV-326-326, it will exert superior synergistic effects. This product does not spray frost, and its volatility is extremely low, which can improve the weather resistance of the product. Suitable for a variety of rubber, plastics, synthetic resins, latex, petroleum products, etc.
Antioxidant 2246 can be used as an antioxidant additive for petroleum products, with good oil solubility, good anti-oxidation effect, and low loss of volatilization.
This product is widely used in polypropylene, polyethylene, polystyrene, polyvinyl chloride, chlorinated polyether, ABS, polyoxymethylene, polyamide and other industries, and has a good stabilizing effect on the thermal degradation of almost all polymers. Usually used in an amount of 0.1-1.0%. The amount in the ABS plastic is 0.12-3%. In rubber and plastic products, the dosage is 3-5%, and the dosage in the granulation of polypropylene is about 0.075%. If used in combination with the antioxidant DLTP, the dosage is 0.075%, and the finished product will have better anti-aging properties.
