Silica gel is a granular, glassy, porous form of silica prepared from synthetic sodium silicate. Silica gel is harder than common household gel-like gelatin and agar. It is a naturally occurring mineral that is refined and processed into either granular or beaded form. As a desiccant, it has an average pore size of 2.4 nanometers and has a strong affinity for water molecules. Silicone gel is most commonly encountered in daily life as a small (usually bead 2 x 3 cm) file package. In this form, it is used as a desiccant to control local humidity to avoid damage or degradation of some goods. Since silica gel can add chemical markers and absorb moisture very well, silica gel packs usually bear user warnings about what not to eat. The processed products with silica gel as the main raw material are called silica gel products. Silica gel is a porous substance with different particle sizes that is properly dehydrated from silicic acid gel. Silicone products can be divided into three categories according to the different molding processes Molded silicone Molded silicone products are usually formed by putting solid silicone raw materials with vulcanizing agents into a high-temperature mold and applying pressure through a vulcanizing machine, and high-temperature sulfur is solidified. The hardness of molded silicone is usually 30°C-70°C. The raw materials are matched with the color paste to adjust the color according to the Pantone color card number. The shape of the mold determines the shape of the molded silicone product. The molded silicone product is currently the most widely used in the silicone industry. Mainly used for silicone industrial accessories, buttons, Silicone Gifts, silicone bracelets, silicone watches, key cases, mobile phone sets, silicone kitchen utensils, silicone mats, ice trays, cake molds, etc. Extruded silicone Extruded silicone products are usually formed by extruding silicone through extrusion machines. Generally, the shape of extruded silicone is long, and the tubular shape can be cut at will. However, the shape of extruded silicone has limitations and is widely used in medical equipment and food machinery.
Liquid silicone Liquid silicone products are injection-molded through silicone injection molding. The products are soft and the hardness can reach 10°-40°. Because of their soft characteristics, they are widely used in simulating human organs, medical silicone chest pads, and so on. Special products Special silica gel products are based on the chemical properties of silica gel or the addition of some auxiliary raw materials. Special silica gel products can also have high temperature resistance (up to 330 degrees), food grade (fully in line with US FDA, LFGB standards), medical grade, flame retardant grade. , By adding auxiliary raw materials, it can also have the characteristics of luminous, negative ions, discoloration, etc. We also sell Silicone Case, which is generally made of rubber, soft and elastic, and is often used to protect electronic digital products from accidental drops or wear. If you need a Silicone Wristband, you can also consult us. Silicone wristbands are more associated with various organizational activities, brand promotion, sports, etc. A good design can convey a profound meaning.
