Advantages and disadvantages of solid silica gel and liquid silica gel

Solid silica gel is the abbreviation of solid silica gel compound, commonly known in the industry as high temperature silicone rubber (HTV silicone rubber);

Liquid Silicone Silicone Rubber, abbreviated as LSR, is a Liquid (state) like organic Silicone material with flowing property.

Below from the purpose, characteristics, use methods and other parameters of the two kinds of silica gel advantages and disadvantages of comparison.

USES:

(1) solid silica gel: in the double 25 vulcanization agent under the high temperature vulcanization molding, made of a variety of silica gel articles for daily use, industrial miscellaneous, auto parts and other products, with better physical properties.

Liquid silicone: liquid, easy to form, often used to make mold copy products, and this is a solid silicone rubber is unable to achieve.

Liquid silicone rubber is also a good adhesive material.

Baby supplies, kitchen supplies, medical supplies and other fields

Features:

Solid silicone rubber: the product after the secondary vulcanization can generally pass the FDA test, reach the food grade standards.

Must be vulcanized at high temperature.

Liquid silica gel: according to the processing process can be divided into: condensation type, plus molding 2.

Condensed silicone rubber is generally not up to the food grade standards, plus molding silicone rubber environmental grade high can pass the food grade certification standards.

Both can be vulcanized at room temperature.

Usage:

(1) solid silica gel: mostly single component, can be catalyzed by double 24, double 25 vulcanization agent heating vulcanization molding, often with the plate vulcanization machine pressure test, heating mold use.

After mixing and mixing machine, the cutting machine cut into products and mold suitable size and thickness, and then into the mold, pressure molding machine under a certain temperature mold molding.

Release after complete vulcanization.

Liquid silica gel: the use of AB two-component majority, platinum sulfide system.

In the liquid silicone injection molding machine molding, vulcanization equipment for the injection molding machine.

Injection molding machine process automation, high feeding accuracy, high output (A/B glue mixed in A certain temperature in A few seconds to form), save people, save electricity, save materials and other advantages, liquid silica gel in the silica gel products industry share increases every year.

Advantages and disadvantages of finished products:

(1) solid silica gel products: transparent bottom, vulcanization agent or other covering vulcanization agent fragrance, product parting line, due to low feeding accuracy, there is a flying edge, need to fly artificially.

(2) liquid silicone products: high environmental protection level, high transparency, no odor, easy to process, the product has injection mouth;
