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

Raw materials can be seen as a solid and a liquid. Now let's talk about the difference between the two materials:

1. Shape of liquid silicone rubber and solid:

(1) As the name suggests, liquid silicone rubber is liquid and has fluidity,

(2) Solid silicone rubber is solid and has no fluidity!

2. Application fields of liquid silicone rubber and solid silicone rubber:

(1) Liquid silicone rubber is generally used in baby products, kitchen products and medical products, which can directly contact food and human body,

(2) Solid silicone rubber is generally used in daily necessities, industrial miscellaneous parts and auto parts,

3. Safety of solid silicone rubber and liquid silicone rubber:

(1) Liquid silicone rubber is a food grade material with high transparency and safety. It is sealed and fed without vulcanizing agent and other auxiliary materials.

(2) Solid silicone rubber is a transparent environmental protection material. Vulcanizing agent needs to be added during molding to speed up the vulcanization molding time and open mold feeding for molding,

4. Forming method of liquid silicone rubber and solid silicone rubber:

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

The injection molding machine has a very simple process flow (without manual processes such as batching, mixing, cutting and placing in the high-temperature rubber process, only one worker needs to take the product), high product accuracy (all manual procedures are replaced by the machine before molding) and high output (A / b glue is mixed and formed in a few seconds at a certain temperature), saving people, electricity and materials. It can produce all products produced by high-temperature glue! It is a mainstream in the development of silicone rubber materials in the next few years.

(2) Solid silicone rubber molding is that the raw materials are solid pieces. After mixing by the mixer, the cutting machine cuts the products and molds into appropriate size and thickness, and then puts them into the mold. It is molded at a certain temperature under the pressure molding machine. When demoulding, it is similar to plastic products, and the molds also need to be cleaned.

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

(1) Liquid silicone rubber has high transparency and no peculiar smell. The product has a glue injection port.

(2) Solid silicone rubber transparent bottom, with the smell of vulcanizing agent or other covering vulcanizing agent, and the product has no glue injection port.
