Awareness of Rubber

Rubber is ubiquitous in our lives, ranging from daily items such as erasers and sports shoes to large ones such as car tires. It is an indispensable raw material in human life.
In theory, it refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can deform under the action of external force, and can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer with a long chain structure and often a large molecular weight, greater than hundreds of thousands。

Early rubber was obtained from the latex of the rubber tree, which was processed into a material that was elastic, insulating, impermeable to water and air. It is a highly elastic polymer compound. Rubber is divided into two types: natural rubber and synthetic rubber. Natural rubber is made by extracting gum from plants such as rubber trees; synthetic rubber is obtained by the polymerization of various monomers.

The main structure of natural rubber is isoprene , while synthetic rubber has different structures according to different side chain branches.

The following will introduce two categories of natural rubber and synthetic rubber, please select each category from the left-hand menu
