N-Phenyl-1-naphthylamine CAS 90-30-2 is a colorless flaky crystal that turns light gray or brown when exposed to air or sunlight. N-Phenyl-1-naphthylamine is a commonly used antioxidant in natural rubber, diene synthetic rubber, chloroprene rubber, etc. It has a good protective effect against heat, oxygen, flex, weathering, fatigue, etc. In chloroprene rubber, it also has the property of resisting ozone aging and has a certain inhibitory effect on harmful metals.
1 N-Phenyl naphthylamine (commonly referring to n-phenyl-1-naphthylamine, also known as an antioxidant) is mainly used in the industrial field.
Antioxidants in the rubber industry
This is its main use. N-Phenyl-1-naphthylamine can effectively inhibit the aging of natural rubber, diene synthetic rubber (such as styrene-butadiene rubber, butadiene rubber), chloroprene rubber, etc. during use or storage due to factors such as heat, oxygen, light, flexing (repeated deformation), and weather conditions (such as sun exposure and rain), thereby extending the service life of rubber products. In addition, in chloroprene rubber, N-Phenyl-1-naphthylamine also has a certain anti-ozone aging effect, and at the same time has a certain inhibitory effect on harmful metal ions that may exist in the rubber (such as copper, manganese, etc.), reducing their catalytic aging effect on the rubber. In practical applications, N-Phenyl-1-naphthylamine is often used in combination with other antioxidants (such as antioxidant AP, DNP, 4010, etc.) to enhance the protective effect. It is mainly used for manufacturing tires, rubber hoses, rubber belts, rubber rollers, rubber shoes, insulation layers of submarine cables, etc.
Stabilizers in the plastic industry
N-Phenyl-1-naphthylamine can be used as a heat stabilizer in the processing and application of plastics such as polyethylene, helping plastics resist degradation or aging caused by high temperatures and maintaining the mechanical properties and appearance stability of plastics.
Organic synthesis intermediates
N-Phenyl-1-naphthylamine can be used in the synthesis of dyes, other organic compounds, etc., and participate in reactions as raw materials or intermediates in the field of fine chemicals.
