styrenated phenol DSP， Also known as stilbene phenol, the English name is: Distyrenated Phenol As an important organic compound, it has a wide range of applications in multiple fields. The following is a detailed analysis of its main functions and uses:
1、 Function
Anti aging effect: styrene phenol DSP， Stilbenephenol is a medium strength anti-aging agent that has good protective effects against aging such as thermal oxidation, weathering, and light deflection. This enables it to effectively extend the service life of rubber products.
Antioxidant properties: Styrene phenol DSP， Phenol stilbene can resist the effects of oxidation, heat, and light, prevent the breakage and cross-linking of rubber molecular chains, and maintain the elasticity and physical properties of rubber.
Chemical Stability: Styrene Phenol DSP， Phenol stilbene has good chemical stability in multiple applications and can maintain its performance and service life under harsh environmental conditions.
2、 Purpose:
Rubber industry: Styrene phenol is used as a stabilizer and anti-aging agent in the rubber industry, widely applicable to natural rubber, butadiene rubber, styrene butadiene rubber, and various synthetic rubbers. It can effectively improve the antioxidant properties of rubber and extend the service life of rubber products.
Plastic industry: Styrene phenol is used as an antioxidant for polyolefins and polyformaldehyde in the plastic industry, helping to improve the durability and stability of plastic products
styrenated phenol DSP It is a product obtained by alkylation reaction of styrene and phenol under the action of catalyst. According to the number of styrene substituents, the product has different uses. A product mainly containing stilbene phenol, also known as anti-aging agent DSP， styrenated phenol DSP， The appearance is a light yellow viscous liquid. It is an important chemical raw material mainly used as a stabilizer for styrene butadiene rubber and chlorobenzene rubber, as well as an antioxidant for polyolefins and polyformaldehyde. It can delay the oxidation process of synthetic polymer materials and ensure the stability of polymer product processing and application. Styrene phenol, as an environmentally friendly rubber antioxidant, is also a widely used alkylphenol antioxidant
