Sinanox® 300 Usage

1. Antioxidant 300 is a thio-bisphenol antioxidant with the dual function of free radical terminator and hydroperoxide decomposer. It has good compatibility, low volatility, resistance to water extraction, low migration, good thermal stability and high antioxidant efficiency, and can be used in combination with thioester antioxidants or carbon black to produce excellent synergistic effects. It is suitable for polyethylene, polypropylene, polystyrene, PVC, polybutadiene, synthetic rubber, hot melt adhesives, rosin resins, ABS resins, especially for polyethylene wire and cable, to better maintain tensile strength, melt index, elongation, electrical properties. The general dosage is 0.1-0.5%.

2. Suitable for: polyethylene with the following advantages: better maintain the physical properties of its raw materials, (such as tensile strength, elongation, melt index, etc.), good preservation of its electrical properties, high thermal stability, enhance the weather resistance of products, anti-aging effect is four times the effect of the general anti-aging agent, compared with other commonly used antioxidants less volatile, with a special synergistic effect when shared with carbon black.
