The basic working principle of rubber antioxidants

Rubber antioxidants are a class of additives used to protect rubber products from oxidation damage. The oxidation process can cause the physical properties of rubber materials to deteriorate, such as hardening, cracking and fading. Antioxidants delay and prevent these damages by absorbing oxygen free radicals or blocking oxidation chain reactions, ensuring the long life and stability of rubber products.

Considerations for choosing

Choosing the right rubber antioxidant requires considering multiple factors, including the type of rubber, the use environment, and the product requirements. First, you should understand the working temperature and exposure environment of the rubber product, such as whether it will be exposed to ultraviolet rays or chemicals for a long time. Secondly, according to the different rubber materials, such as natural rubber and synthetic rubber, choose the right antioxidant ingredients, such as amines, phenols, etc. In addition, pay attention to the dosage and dispersibility of the antioxidant to ensure that it is evenly distributed in the rubber matrix.

Characteristics of different types of antioxidants and their applicable scenarios

Rubber antioxidants are mainly divided into two categories: amine antioxidants and phenolic antioxidants. Amine antioxidants (such as diphenylamine derivatives) have excellent high temperature stability and ozone resistance, and are suitable for high temperature working environments such as tires and industrial rubber products. Phenolic antioxidants (such as BHT, butylated hydroxytoluene) have good antioxidant effects in medium and low temperature environments and are often used in ordinary rubber products and daily products.

Supplier Recommendations

When choosing an antioxidant supplier, the following points should be considered: the supplier's technical support capabilities, the consistency and stability of product quality, the reasonableness of price and the timeliness of delivery. High-quality suppliers can usually provide detailed technical information and actual case analysis to help customers select and apply suitable antioxidants. Establishing a long-term cooperative relationship with a supplier will help to quickly resolve technical problems and ensure product quality.

Actual case analysis

In actual applications, a rubber product manufacturer faced the problem of aging of rubber products, which resulted in a short product life and had a negative impact on customer satisfaction. Through cooperation with suppliers, an amine antioxidant suitable for its product characteristics was selected. After testing and improvement, the antioxidant performance of rubber products was significantly improved, the service life was extended by about 20%, customer satisfaction was improved, and the company's market competitiveness was enhanced.

In short, rubber antioxidants play an indispensable role in rubber products. Understanding their basic working principles, key points for selection and use, and the characteristics of different types can help companies make wise decisions in practical applications and improve product quality and market competitiveness. Cooperating with high-quality suppliers to jointly solve technical problems will bring long-term business success to companies.
