Many natural materials we come into contact with are usually composed of polymer materials, such as natural rubber, cotton, human organs, etc. The same is true for artificially synthesized chemical fibers, plastics and rubber. Generally speaking, polymers that are widely used in life and have formed an industrial production scale are called general polymer materials, and those with special uses and functions are called functional polymers. Polymer materials are used to manufacture products that require fine particles or powders, such as plastic powder coatings, 3D printing materials, drug carriers, etc., so grinding into powder is a necessary step.
