Silicone products can be divided into three major types according to the different molding processes
Molded silica gel products are usually pressed through a vulcanizing machine after being put into a solid silicone raw material containing a vulcanizing agent through a high-temperature mold, and high-temperature sulfur is formed into a solid. The hardness of the molded silica gel is usually from 30°C to 70°C. Raw materials with color paste in accordance with Pantone color card number to draw 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 only silicone industrial accessories, buttons, silicone gifts, silicone bracelets, silicone watches, key bags, mobile phone sets, silicone kitchen utensils, silicone mats, ice trays, 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.
Liquid silicone products are injection molded by silicone injection molding. The products are soft and the hardness can reach 10°C-40°C. Due to its soft characteristics, it is widely used in artificial human organs, medical silicone breast pads, and so on.
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.
