Application:
Protection against heat and oxidative degradation: Antioxidant 445 is used in natural rubber (NR) and synthetic rubbers like BR, SBR, NBR, CR, and EPDM.
It's found in products like belting, hoses, seals, gaskets, and other automotive and industrial rubber components.
Synergistic effects: It can be used in combination with other antioxidants, like phenolic and phosphite antioxidants, for enhanced protection in high-temperature applications.
Latex compounds: It's also used in aqueous dispersions in latex compounds (SBR, carbonylated SBR, and NR) to improve resistance to heat and embrittlement during aging.
Hot-melt adhesives: It helps to maintain the stability and performance of hot-melt adhesives over time.
Lubricants: It can be used to stabilize lubricants against oxidation.
Polyamides: It helps to protect polyamides (like nylon) from degradation.
Packing:
20 or 25 kg bags,
Storage:
Temperature: Store in a cool, dry place, ideally below 25°C (77°F). Avoid high temperatures to prevent degradation.
Moisture Protection: Keep in an airtight container to avoid moisture absorption, which can affect stability.
Light Sensitivity : Store in opaque or dark containers away from direct sunlight to prevent decomposition.
