Uses: antioxidant stabilizer 565 is an excellent non-coloring stabilizer for a variety of resin antioxidant and light heat stabilizer. Mainly used for polystyrene, ABS resin, polybutadiene, SBS, SAN and rubber unsaturated bond protection, dosage 0.1-1.0%


Antioxidant 565 is a kind of polymer multi-functional hindered phenolic antioxidant. It is mainly applied to stabilize post-processing of unsaturated rubber. It is very effective for elastomer and can protect materials from production, processing and end-use. Thermal oxidative degradation. Is a good variety of resin antioxidant and light heat stabilizer, with a small amount of added, low volatility, high color fastness, and to prevent the formation of gel characteristics.

Use very effective in the following elastomers:
Polybutadiene rubber (BR)
Iso butyl rubber (IR)
Styrene butadiene rubber (SBR)
Nitrile rubber (NBR)
Carboxylic styrene butadiene rubber latex (XSBR)
Milk styrene butadiene rubber (ESBR)
Solution polymerized styrene butadiene rubber (SSBR)
Thermoplastic styrene butadiene rubber SBS
Thermoplastic styrene butadiene rubber SIS

It can also be used in adhesives, natural and synthetic resins such as ethylene propylene diene monomer (EPDM), ABS plastic, polyamide (PA), high impact polystyrene (HIPS) and polyolefins.
