The mechanism of action of rubber antioxidants

Rubber antioxidants effectively extend the service life of rubber products by preventing chemical reactions such as oxidation, thermal degradation, ozone attack and ultraviolet radiation. These chemical reactions can lead to the breakage of rubber molecular chains and structural damage, which can lead to hardening, cracking, loss of elasticity, and even complete degradation of the material. Therefore, adding rubber antioxidants can significantly improve the durability of rubber materials.

Classification of rubber antioxidants

According to the mechanism of action and chemical properties of rubber antioxidants, they can be divided into the following categories:

• Antioxidants: Mainly used to prevent rubber from aging due to oxidation.
• Anti-ozone agent: mainly used to prevent ozone from attacking rubber materials.
• UV absorbers: Used to absorb UV radiation, thus protecting rubber materials.
• Metal passivator: mainly used to inhibit the degradation of rubber by metal catalysts.

Application areas of rubber antioxidants

Rubber antioxidants are widely used in many industrial fields, including but not limited to:

• Automobile manufacturing: used to produce tires, sealing strips, brake pads, etc.
• Aerospace: Used in the production of key components such as aircraft tires and sealing components.
• Construction industry: used in the production of weather-resistant sealants, rubber roofing materials, etc.
• Electronic appliances: used to produce protective covers, insulation materials, etc.

Market Prospects and Competition Situation

With the increasing demand for high-performance and long-life materials in the industrial field, the rubber antioxidant market shows good development prospects.
