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 the same material. Other than appearance and color, you may not notice the difference. In fact, there are also different differences in hardness and tensile elasticity. Regardless, the main difference is the difference in material, so do you know how different it is?
As the saying goes, interlacing is like a mountain, with extensive knowledge of the silicone products industry. Today we have learned some common sense about silicone products. Silica gel is divided into organic silicon and inorganic silicon, and silicone products can be divided into liquid silicone.

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 and more environmentally friendly, and can fully meet food-grade requirements.

Solid silica gel - Solid silica gel is a cell-based polymer elastic material with the characteristics of high temperature resistance, cold resistance, solvent resistance, hysteresis resistance, anti-adhesion, 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 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 safety. No auxiliary materials such as vulcanizing agents are added during the molding process, and they are sealed and molded.

Solid silicone is a transparent and environmentally friendly material. During the molding process, vulcanization molding time is required, and the mold is formed by opening the mold.

Molding method - Liquid silicone is injection molding 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 processes such as batching, rubber mixing, cutting, arranging in high-temperature glue process, only one worker can bring the product), and the product precision is high (all manual procedures before molding are all replaced by the machine) , high output (A/B glue is mixed at a certain temperature for a few seconds), saving manpower, saving electricity, saving materials and many other advantages, and can produce full-high temperature rubber production products.

Solid silicone rubber molding is a solid piece of material. After kneading with a mixer, the cutting machine cuts the product and mold to the appropriate size and thickness, then puts it into the mold and molds it under a pressure forming machine at a certain temperature. When demoulding is similar to plastic products, the mold also needs to be cleaned.

How to distinguish liquid silicone and solid silicone products

Liquid silicone products have high transparency, no odor, and have a glue injection port.

Solid silicone products have low clarity, vulcanizing agents, or other fragrances that mask the vulcanizing agents.

Liquid silicone is commonly used in baby products and kitchen products as well as medical products that come into direct contact with food and the human body.

Solid silicone is commonly used in daily necessities and industrial miscellaneous products as well as automotive parts
