Many people know this type of plastic buttons, but they do not understand the type and characteristics of plastic buttons. The types of fasteners used for these types of fasteners include transparent molded plastics such as transparent polystyrene, polycarbonates, acrylics (372.613 moldings, etc.), AS resins, etc. The main features of these buttons are as follows:
1. Transparent Polystyrene Button This button has good transparency, cheap material, easy injection, 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 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, most of these materials are used in button manufacturing to manufacture high-purity, high-transparency buttons whose appearance is similar to that of crystal glass. Buttons made of them or used alone Fashion buttons, or combined buttons with other materials, are popular in women's fashion. The disadvantage of this type of button is that the scratch resistance, organic solvent resistance and temperature resistance of the surface are not good, 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 for the production of transparent, translucent rope fasteners. Because the resin is limited by the mechanical properties of the material, the durability of the buttons is not good and the grade is low.
