Unsaturated injection molded buttons are a kind of button with better mechanical properties in all button accessories. The mechanical properties of materials refer to the macro-mechanical properties of the materials under normal temperature and static load. Generally we are also more common in the button mall.
When the color has been determined before production, such buttons are often buttons that are colored directly into the resin and injected into various colors. When the volume of buttons is larger. Often used premixed pigment coloring method. The advantage of using this method is that relatively inexpensive plastics can be selected to reduce costs and facilitate injection molding. Commonly used plastics for pigmented plastic buttons are polypropylene, ABS, etc. The main advantage of using polypropylene plastic is that this type of material is inexpensive, has low requirements for molds, has good injection moldability, and has excellent corrosion resistance of injection molded products (almost resistant to most organic solvents and acid and alkali corrosion). Good mechanical properties. In addition to polypropylene, ABS is also often used to produce colored plastic buttons, but ABS is more expensive than polypropylene and inferior in organic solvent resistance than polypropylene. In general, the overall performance of ABS coloring buttons is not as good as that of polyethylene, so it is not widely used.
