Silicone products can be classified according to their properties and functions, including the classification of silicone raw materials and silicone products. First, let's introduce some classification methods for silicone products:
1. Molded silicone rubber
Molded silicone products are usually formed through high-temperature molds, where solid silicone raw materials with vulcanizing agents are added, and pressure is applied through a vulcanizing machine. The high-temperature sulfur forms a solid form, and the hardness of molded silicone is usually between 30 ° C-70 ° C. The color of the raw material and color paste is adjusted according to the Pantone color card number. The shape of the mold determines the shape of the molded silicone product, which is currently the most widely used type in the silicone industry. Mainly used for silicone industrial accessories, buttons, silicone gifts, silicone bracelets, silicone watches, keycases, phone cases, silicone kitchenware, silicone pads, ice grids, cake molds, and more.
2. Extrude silicone rubber
Extruded silicone products are usually formed by extruding silicone through an extrusion machine. Generally, the shape of extruded silicone is long and tubular, which can be freely cut. However, the shape of extruded silicone has limitations and is widely used in medical devices and food machinery.
3. Liquid silicone rubber (LSR)
Liquid silicone products are molded by silicone injection molding. The products are soft and the hardness can reach 10 ° C-40 ° C. Because of their soft characteristics, they are widely used in the simulation of human organ, medical silicone breast pads, etc.
4. Special silicone rubber 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 Celsius), food grade (fully compliant with FDA and LFGB standards in the United States), medical grade, flame retardant grade, and can also have characteristics such as night light, negative ions, color change, etc. by adding auxiliary materials.
