What is resin?
Resin usually refers to products inclined to softening or melting after receiving heat. When softening, it shows a trend toward flowing under the influence of external forces. Under normal temperature, it is in solid, semi-solid state, and sometimes liquid organic polymer. Broadly speaking, any macromolecule compound that can be used as a raw material for plastic processing can be called resin.
What can resins do for you?
