Applications
Antioxidant Fork 4426-S belongs to the thioether antioxidants. When used in combination with phenolic antioxidants, it has a good synergistic effect, especially for the thermal oxidation aging resistance of polymer materials, which is unmatched by other antioxidants. Antioxidant Fork 4426-S is compounded with bisphenol antioxidants and bisphenol monoacrylate antioxidants to form a new type of antioxidant, which can be widely used in synthetic materials such as BR, SBR, SBS, ABS, etc. Compared with traditional antioxidants 264, TNPP, 1076, 168, etc., the thermal oxidation aging resistance is significantly improved, and the anti-discoloration performance is significantly improved. This product can protect natural and synthetic polymers based on isoprene and butadiene chemistry.
