In our daily life, we often use a smooth surface, different shapes and colors, from the appearance of plastic buttons. Actually, this kind of button is not as simple as we can see. It still has obvious differences. First, we need to distinguish between resin and plastic buttons from such buttons.
Distinguish between resin and plastic: 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. Plastics refer to resins (or direct polymerization of monomers during processing) as the main component, and additives such as plasticizers, fillers, lubricants, and colorants as auxiliary components, which can be flow-formed during processing. material. From this it can be seen that the resin is one of the raw materials for plastics and the plastic is the finished product of the resin. In general, resin is not molded, and it is plastic after molding. From the chemical properties of these two materials, plastics are divided into two categories: thermosetting and thermoplastic. Thermosetting plastics cannot be remolded, and thermoplastics can be repeatedly produced.
The difference between a resin button and a plastic button is the difference in processing methods, rather than the difference between the resin and the plastic itself. The resin button is formed by heating, cooling, solidifying, cutting, etc. the liquid material through a special tube, or by applying a liquid resin on the surface of the drum, after which it is solidified and then press-formed, and then enters the subsequent processing; and the plastic button is It consists of solid materials, most of which are resin pellets, injection molded by injection molding machines and molds.
Because the processing methods of the two materials are different, the resulting finished products have different effects. The surface of the resin button is smooth and has a thick appearance, and it should also be more extensive. The plastic buttons can produce various styles of buttons according to the changing shape of the mold, and it is also easier to electroplate with respect to the resin buttons.
