The buttons are resinous and plastic. Then talk about the difference between resin and plastic.
The resin usually refers to the range of softening or melting after being heated, and tends to flow under external force when softened, and is a solid, semi-solid, and sometimes liquid organic polymer at room temperature. Broadly speaking, any polymer that can be used as a raw material for processing plastic products is called a resin.
Plastic refers to the resin (or direct polymerization of monomers used in the process of processing) as the main component, plasticizers, fillers, lubricants, colorants and other additives as ancillary components, in the process of flow molding material.
It can be seen that resin is one of the raw materials for plastics and plastic is the finished product of resins. In other words, the unformed resin is plastic and it is plastic after molding.
