The types of materials for these types of buttons include injection molded transparent plastics, such as transparent polystyrene, polycarbonate, acrylic resin (372.613 molding plastics, etc.), AS resin, etc. The main features of these buttons are as follows: 1. Transparent Polystyrene Buttons This button has good transparency, low material cost, easy injection molding, but it is fragile, and it is not resistant to high temperature and solvent, so it can only produce low-grade buttons. 2. Polycarbonate button (PC) Polycarbonate is an engineering plastic that is not only transparent, but also has excellent mechanical properties, especially its good resilience, and it is not easily broken. The disadvantages are the high cost and poor injection molding performance. 3. Acrylic resin button This is a kind of plastic with the highest light transmittance and the best transparency. There are many types of resin that can be used for injection molding. The main models in China are 372, 613, and 504, but the overall light transmittance is slightly poor. Due to the high light transmittance and pure color of acrylic resin, in the button manufacturing industry, most of these materials are used to make high-purity, high-transparency buttons, the appearance of which is like the effect of crystal glass, the buttons made or the fashion buttons alone, Or combined with other materials into a combination of buttons for women's fashion, is quite popular. The disadvantage of this kind of button is the scratch resistance of the surface, resistance to organic solvent and temperature resistance, and it is not suitable for high-grade and durable clothing. 4.K resin button K resin is a styrene-dibutylene copolymer. It is characterized by good transparency, good material flexibility and easy injection molding. Buttons made of this resin often have a certain degree of elasticity, and are mostly used to produce transparent, translucent rope clasps. As the resin is limited by the mechanical properties of the material, the buttons have poor durability and low grades.
