Show you the difference between liquid silicone and solid silicone

The main difference between liquid silicone and solid silicone is that one is a liquid and the other is a solid; But after processing the finished product, the two are not so easy to tell apart. Today, liquid silicone feeder manufacturers take you to understand the difference between liquid silicone and solid silicone:

Different from shape:

Liquid silicone rubber is liquid and has fluidity; Solid silicone rubber is solid and has no fluidity.

Different from the field of use:

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

2. Solid silicone rubber is generally used for daily necessities, industrial miscellaneous parts and auto parts.

3. The safety of liquid silicone and solid silicone: liquid silicone is a food grade material with high transparency and high safety. When forming, do not add vulcanizing agent and other auxiliary materials, and sealed forming. Solid silicone rubber is a transparent material. Curing agent needs to be added during molding to speed up curing molding time.

Different from the molding method

1. Liquid silicone is injection molding liquid silicone rubber (LSR) : injection molding liquid silicone rubber, vulcanization equipment for Injection molding machine. The process flow of the injection molding machine is very simple, the product precision is high, the output is high, the output is high (A/B glue is mixed for a few seconds at a certain temperature), the advantages of saving people, saving electricity, saving materials, etc., can produce all high temperature glue products; It is the mainstream of the future development of silicone rubber materials.

2. Solid silicone molding is that the raw material is a solid, mixed by the mixer, cut into the appropriate size and thickness of the product and the mold, and then enter the mold, and the pressure molding machine is formed at a certain temperature. When demoulding is similar to plastic products, it is also necessary to clean the mold.

Different from the finished product

Liquid silicone has high transparency, no odor, and the product has a glue injection port;

Solid silicone transparent base, with vulcanizing agent or other covering vulcanizing agent fragrance, product no glue mouth.

2. What is the difference between the molding process of liquid silicone and solid silicone?

First introduce solid silicone rubber:

In industry, solid silicone rubber is made of water glass (sodium silicate) as raw material, hydrolyzed in an acidic medium to form a gel, and then aged. Wash. Silicone is made during the drying process and is translucent or a white solid, depending on the water content. There are irregular particles on the market. Microspherical silicone rubber is a catalyst carrier commonly used in fluidized bed operation.

Introduce the process of liquid silicone rubber:

In industry, liquid silicone rubber is usually prepared by ion exchange method. It is a translucent milky liquid with high stability. The silica sol becomes a porous solid after drying. For example, in the production of acrylonitrile (phosphate-molybdenum-bismuth)/silicon oxide catalyst, a solution containing the active ingredient is mixed with silica sol by spray drying to make microsphere catalyst; Mainly used for food grade daily necessities and maternal and child supplies.
