According to the form, it is divided into block rubber, latex, liquid rubber and powder rubber. milk the glue is a colloidal aqueous dispersion of rubber; the liquid rubber is a rubber oligomer, which is generally a viscous liquid before being vulcanized; the powder rubber is processed into a powder to facilitate the preparation and processing. The thermoplastic rubber developed in the 1960s was formed by a thermoplastic processing method without chemical vulcanization. Rubber is divided into general and special types according to its use. It is an insulator and is not easy to conduct electricity, but it may become a conductor if it is wet or at a different temperature. Conductivity is an easy condition for the conduction of electrons with 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. Natural rubber consumption accounts for 1/3, and synthetic rubber consumption accounts for 2/3.
According to the appearance of rubber: rubber can be divided into four categories: solid rubber (also known as dry rubber), milk 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-generic synthetic rubber, special synthetic rubber and special synthetic rubber.
According to the physical form of rubber: rubber can be divided into hard rubber and soft rubber, raw rubber and rubber compound.
