Silicone products are widely used in various industries such as silicone kitchenware, silicone gifts, industrial accessories, artificial body parts, etc. due to their high quality characteristics such as safety, non-toxic, tasteless, and high temperature resistance. Here we take a look at the specific classification of silicone products. use.
Silicone products can be divided into three major categories based on the different molding processes:
1. molded silicone
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. 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 the most widely used in the silicone industry.
Molded silicone is 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.
2. extruded silicone
Extruded silicone products are usually formed by squeezing the silicone through an extrusion machine. Generally, the shape of the extruded silicone is long, and the tubular shape can be freely cut, but the shape of the extruded silicone is limited.
Extruded silica gel is widely used in medical devices and food machinery.
3. liquid silicone
Liquid silicone products are injection-molded through silicone injection molding. The products are soft and can reach a hardness of 10°C to 40°C due to their soft properties.
Liquid silicone is widely used in the simulation of human organs, medical silicone breast pad, and so on.
4. special products
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.
