In life, we should see many different kinds of silicone products, but I don't know if you have noticed that not every one is a material. You may not be able to tell the difference apart from appearance and color. In fact, there are also different differences in hardness and tensile elasticity. Whether the main difference is the difference in the material, do you know how it is different?


As the saying goes, interlaced scanning is like a mountain, with extensive knowledge of the silicone product industry. Today we have understood some common sense of silicone products, silicone is divided into silicone and inorganic silicon, silicone products can be divided into liquid silicone.


Liquid silicone - liquid silicone resin is a relatively solid high temperature vulcanized silicone rubber. It is a liquid glue, good fluidity, vulcanization speed, safer, more environmentally friendly, can fully meet food grade requirements.


Solid silica gel - solid silica gel is a kind of cellular polymer elastic material, with high temperature resistance, cold resistance, solvent resistance, anti-stagnation, anti-viscosity, electrical insulation, chemical industry and other characteristics, a wide range of applications.


Comparison of liquid silica gel and solid silica gel


Shape - As the name suggests, liquid silicone is in a liquid state and has fluidity, while solid silicone is solid and has no fluidity.
Safety - Liquid silicone is a food material with high transparency and high safety. Auxiliary materials such as vulcanizing agents are not added during the molding process, and they are sealed and moulded.


Solid silica gel is a transparent and environmentally friendly material. Vulcanization molding time is required in the molding process, and molding is done by opening the mold.


Molding method - Liquid silicone rubber is injection liquid silicone rubber (LSR) : full name injection liquid silicone rubber, injection molding machine vulcanization equipment.


The injection molding machine process is very simple (no manual process, such as batching, rubber mixing, cutting, arranged in the high-temperature glue process, only one worker can bring the product), high product accuracy (all manual procedures before forming), high output (A/B glue mixed at a certain temperature for a few seconds), saving manpower, saving electricity, saving materials and many other advantages. Can produce all high temperature rubber production products.


Solid silicone rubber molding is a solid piece of material. After kneading with a mixer, the cutter cuts the product and the mold to the appropriate size and thickness, then places it into the mold and molds it at a certain temperature under a pressure forming machine. When stripping is similar to plastic products, it is also necessary to clean the mold.


How to distinguish between liquid silicone and solid silicone products


Liquid silicone products have high transparency, no odor, and the product has a glue-filling port.


Solid silicone products have low transparency, vulcanization agents or other fragrances that mask vulcanization agents.
Liquid silicone is commonly used in baby products and kitchen items as well as medical supplies that come into direct contact with food and the human body.
Solid silicone resins are commonly used in the household and industrial miscellaneous and automotive sectors
