In life, we should see many different kinds of silicone products, but I don't know if you notice that not every kind is a material. Other than appearance and color, you may not see the difference. In fact, there are also differences in hardness and tensile elasticity. Whether the main difference is in the material, do you know how it differs?
As the saying goes, interlaced scanning is like a mountain with a broad understanding of the silicone product industry. Today we have learned some common knowledge of silica gel products, among which silica gel is divided into organic silicon and inorganic silicon, and silica gel products can be divided into liquid silica gel.

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

Solid silica gel—Solid silica gel is a cellular polymer elastic material, which has the characteristics of high temperature resistance, cold resistance, solvent resistance, anti-stagnation, anti-sticking, electrical insulation, chemical industry, etc., and has a wide range of applications.

Comparison of liquid silica gel and solid silica gel

Shape—As the name suggests, liquid silicone resin is in a liquid state and has fluidity. Solid silica gel is solid and has no fluidity.

Safe-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 molded.

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

Molding method-Liquid silicone 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 molding, all replaced by the machine) , High output (A / B rubber is mixed for a few seconds at a certain temperature), saving manpower, saving electricity, saving materials, and many other advantages, it can produce full-temperature rubber production products.

Solid silicone rubber moldings are 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 puts them into the mold and molds them at a certain temperature under a pressure forming machine. When mold release is similar to plastic products, the mold also needs to be cleaned.

How to distinguish between liquid silicone and solid silicone products

Liquid silicone products have high transparency and no odor, and the products have glue injection ports.

Solid silicone products have low transparency, vulcanizing agents or other flavors that mask the vulcanizing agent.

Liquid silicone is commonly used in baby and kitchen supplies, and medical supplies that come in direct contact with food and the human body.

Solid silicone resins are commonly used in daily necessities and industrial miscellaneous and automotive parts.
