If it is made into a finished product, it is generally not easy to distinguish.

As for the raw materials, you can see that one is solid and the other is liquid. Now let’s talk about the differences between the two materials:

1. Appearance of liquid silicone and solid:

(1) As the name implies, liquid silicone is in a liquid state and has fluidity.

(2) Solid silica gel is in a solid state and has no fluidity!

2. Application areas of liquid silica gel and solid silica gel:

(1) Liquid silicone is generally used in baby products, kitchen supplies and medical supplies, and can directly come into contact with food and the human body.

(2) Solid silica gel is generally used in daily necessities, industrial miscellaneous parts, and auto parts, etc., with a wide range of applications.

3. Safety of solid silica gel and liquid silica gel:

(1) Liquid silicone is a highly transparent and safe food-grade material. No auxiliary materials such as vulcanizing agents are added during molding, and the materials are sealed and fed into the molding.

(2) Solid silicone is a transparent and environmentally friendly material. When molding, a vulcanizing agent needs to be added to speed up the vulcanization molding time. Open mold feeding is required for molding.

4. Molding methods of liquid silicone and solid silicone:

(1) Liquid silicone is injection molded liquid silicone rubber (LSR): its full name is injection molded liquid silicone rubber, and the vulcanization equipment is an injection molding machine.

The injection molding machine has a very simple process (no manual processes such as ingredients, mixing, cutting, and placement of materials in the high-temperature glue process are required, only one worker is required to take the product), and the product is highly accurate (all manual procedures before molding are required) All replaced by machines), high output (A/B glue is mixed at a certain temperature and formed in a few seconds), saves manpower, saves electricity, saves materials and many other advantages, it can produce all products produced with high-temperature glue! It will be the mainstream development of silicone rubber materials in the next few years.

(2) Solid silicone molding is when the raw materials are solid pieces. After being mixed by a mixer, the cutting machine cuts the product into a suitable size and thickness for the mold, and then puts it into the mold. The pressure molding machine presses and molds at a certain temperature. When demoulding is similar to plastic products, the mold also needs to be cleaned.

5. What is the difference between liquid silicone and solid silicone products?

(1) Liquid silicone has high transparency, no odor, and the product has a glue injection port.

(2) Solid silicone has low transparency, has vulcanizing agent or other scent that covers the vulcanizing agent, and the product has no glue injection port.
