The difference between liquid silicone and solid silica gel

The difference between liquid silicone and solid silica gel

First, the shape distinction

Liquid silicone is in a liquid state and has fluidity; solid silica gel is solid and has no fluidity.

Second, distinguish from the field of use

1. Liquid silicone is generally used in baby products and kitchen supplies as well as medical supplies. It is in direct contact with food and human body.

2, solid silicone is generally used in daily necessities and industrial miscellaneous items and auto parts.

3, the safety of liquid silica gel and solid silica gel: liquid silica gel is a high transparent and high-safe food grade material, no auxiliary materials such as vulcanizing agent are added during molding, and the sealing material is formed by sealing. Solid silica gel is a transparent material. It needs to be vulcanized to accelerate the vulcanization molding time and form mold by open molding.

Third, distinguish from the molding method

1. Liquid silicone is injection molding liquid silicone rubber (LSR): the full name is injection molding liquid silicone rubber, and the vulcanization equipment is injection molding machine. The injection molding machine has a very simple process, high product precision, high output (A/B glue is mixed for a few seconds at a certain temperature), saving people, saving electricity, saving materials and many other advantages, and can produce all high temperature rubber production. The product is a mainstream in the development of silicone rubber materials in the coming years.

2, solid silicone molding is the raw material is a piece of solid, after mixing by the mixer, the cutting machine cut into the appropriate size and thickness of the product and mold, and then put into the mold, pressure forming machine under a certain temperature molding. When demolding is similar to plastic products, it is also necessary to clean the mold.

Fourth, distinguish from the finished product

The liquid silicone has high transparency and no odor. The product has a glue injection port; the solid silicone has a transparent bottom, and has a vulcanizing agent or other fragrance that covers the vulcanizing agent. The product has no glue injection port.
