According to the shape, it is divided into block raw rubber, latex, liquid rubber and powder rubber. Latex is a colloidal water dispersion of rubber; liquid rubber is an oligomer of rubber, which is generally a viscous liquid before being vulcanized; powder rubber is a latex that is processed into a powder to facilitate ingredients and processing. The thermoplastic rubber developed in the 1960s does not require chemical vulcanization, but is formed using a thermoplastic processing method. Rubber is divided into general and special types according to use. It is an insulator and it is not easy to conduct electricity, but it may become a conductor if it is exposed to water or a different temperature. Conduction refers to the ease of conduction of electrons of molecules or ions inside a substance. According to the source and method of raw materials: rubber can be divided into two categories: natural rubber and synthetic rubber. Among them, the consumption of natural rubber accounts for 1/3, and the consumption of synthetic rubber accounts for 2/3.

According to the appearance of rubber: rubber can be divided into four categories: solid rubber (also known as dry rubber), milky rubber (referred to as latex), liquid rubber and powder rubber.

According to the properties and uses of rubber: In addition to natural rubber, synthetic rubber can be divided into general synthetic rubber, semi-general synthetic rubber, special synthetic rubber and special synthetic rubber.

According to the physical form of rubber: rubber can be divided into hard and soft rubber, raw rubber and mixed rubber.
