Abstract: Since the invention of the rubber vulcanization method in the United States in 1839, this technology has been widely used in various production enterprises in the society, and has become one of the most widely used chemical material production technologies in social development, which is also the development of rubber production technology. A solid foundation has been laid. This paper researches and explores the research and development of foamed rubber products, the selection of main materials, the selection of foaming agents, the vulcanization system, and the selection of matching reinforcing fillers and processing technology, aiming to provide reference for peer work.
Key words: foamed rubber; foaming agent; vulcanization system; compounding; rubber product technology
In recent years, with the continuous emergence of materials such as vulcanization accelerators and anti-scorch agents, the vulcanization time has been shortened and the properties of rubber have been further improved. As of now, rubber properties have been significantly improved from the initial rubber formulation to the modern base formulation. Although this formula can be vulcanized, it takes a long time and has poor rubber performance; for this reason, it is particularly important to study the combination and process of foamed rubber products in the current research on rubber products.

1. Overview of distribution of rubber products
Foamed rubber products use rubber as the base material and are produced by physical foaming or chemical foaming to obtain sponge-like rubber porous structures. This technology has been widely used in various production industries, such as automotive door and window seals, cushions, building construction gaskets, anti-seismic materials, sports protection facilities, etc.
1. The concept of foam rubber
The so-called foamed rubber is also widely called rubber foaming technology, which is a treatment method that uses a specific foaming agent to treat rubber so that the rubber has characteristic properties. This technology is widely used in the current production field and is the most common method in the current production work.
2. Classification of foam rubber products
Foamed rubber products are currently one of the most widely used products in the production field. According to the pores, they can be divided into two types: microporous structure and porous structure. The microporous structure can be divided into individual foamed products and continuous foamed products. According to the raw material of rubber, this product can be divided into natural rubber foam products, isoprene foam products, SBR foam products, ethylene-propylene rubber foam products, etc.
