Special silicone products are based on the chemical properties of silicone or the addition of some auxiliary materials. Special silicone products can also have high temperature resistance (up to 330 degrees), food grade (full compliance with US FDA, LFGB standard), medical grade, flame retardant grade. , By adding auxiliary materials can also have, luminous, negative ions, discoloration, and other characteristics.
Liquid silicone products are injection molded by silicone injection molding. The products are soft and can reach a hardness of 10°C to 40°C. Due to their soft characteristics, they are widely used in artificial body parts, medical silicone breast pads, and so on.
Molded silica gel products are usually pressed through a vulcanizing machine after being put into a solid silica gel raw material containing a vulcanizing agent through a high-temperature mold, and high-temperature sulfur is formed into a solid, and the hardness of the molded silica gel is usually from 30°C to 70°C. Raw materials with color paste in accordance with the Pantone color card number to draw the color, the shape of the mold determines the shape of molded silicone products, molded silicone products are currently the most widely used in the silicone industry. Mainly used for making silicone industrial accessories, buttons, silicone gifts, silicone bracelets, silicone watches, key bags, mobile phone sets, silicone kitchenware, silicone mats, ice tray, cake molds and so on.
Extruded silicone products are usually formed by squeezing silicone through an extrusion machine. Generally, the shape of the extruded silicone is long, and the tubular shape can be freely cut. However, the shape of the extruded silicone is limited, and it is widely used in medical devices and food machinery. use.
This process is a more complex process, molding such as molding silicone, but also with liquid glue, suitable for multi-color products, many crafts are made using this process.
