AO 168 | Phosphite Antioxidant Stabilizer – Ecochem China ...

Antioxidant 1098 is a sterically hindered phenolic antioxidant used to stabilize polymers, particularly polyamides, by scavenging free radicals and preventing degradation from heat and oxygen. Known for its non-discoloring properties and high efficiency, it enhances product durability and is compatible with a wide range of materials like polyacetals, polyurethanes, and rubbers. Its chemical name is often listed as N,N'-hexane-1,6-diylbis[3-(3, 5-di-tert-butyl-4-hydroxyphenyl)propionamide], and its CAS number is 23128-74-7.

Mechanism: It works by neutralizing free radicals and decomposing peroxides, which protects polymer chains from breaking down and maintains the material's integrity.
Primary use: It is particularly effective for stabilizing polyamides (like nylon) in molded parts, fibers, and films, but it is also suitable for other polymers such as polyacetals, polyesters, polyurethanes, and elastomers.
Performance: It provides excellent heat resistance, good extraction resistance, and high long-term thermal stability. It also helps protect the color of the polymer during processing and use.
Physical properties: It is a non-toxic, non-polluting, and non-discoloring antioxidant. It is low in volatility and is sparingly soluble in water, but soluble in many organic solvents.
Application: It can be added at various stages, including prior to polymerization or through dry blending with polymer chips before processing.
Usage: Suggested concentrations range from
$0.05 %$
to
$1.0 %$
depending on the specific polymer and stability required. It can be used alone or in combination with secondary antioxidants for an enhanced effect.
