The silica gel we usually say has two physical states, one is a liquid liquid; the other is a solid. Non solid silica gel that can flow like water is called liquid silica gel. Of course, liquid silicone adhesive has a certain viscosity, which is usually larger than that of water. Therefore, its mobility is not as strong as that of water. Liquid silica gel will react with curing agent or catalyst. It will solidify solid silica gel with different hardness and properties according to different kinds of liquid silica gel.
Liquid silica gel can be divided into different properties and uses.
Die silica gel
Mold liquid silica gel is a new type of mold making material. Compared with the silica gel mold made by mold silica gel, the steel die has great advantages in terms of production efficiency and production cost. Today, mold silica gel has been widely used in toys and gifts industry, medical, electronic, mechanical field, character reproduction, home building decoration and decoration industry, unsaturated polyester resin handicraft industry, simulation of animal and plant sculpture, Buddha carving crafts and other industries.
Offset silica gel
Liquid silica gel is used to make print head, mainly used in plastic toys, electroplating products, electronic toys, trademark, irregular pattern printing. The printing head is to make the pattern on the steel plate as the carrier, and then the pattern on the plate is transferred to the toy product. Liquid silica gel can be used to control hardness by adding silicone oil.
Electronic encapsulation adhesive
Electronic encapsulation liquid silica gel is mainly used for potting of electronic products. Electronic encapsulation liquid silica gel can play a role of sealing, waterproof, dust-proof, heat conduction, shockproof and insulation for electronic products. In addition, one is a kind of sealant used for LED, which has high transparency and high refractive index.
Hand plate silica gel
Liquid silica gel, also known as the first version of silica gel, is usually used for making the hand plate model. Compared with the hand plate, oily sludge and hand plate, the liquid silica gel has the characteristics of abrasion resistance and strong resilience after curing.
Label glue and trademark glue
After the solidification of liquid clothing label silica gel, we often see the clothing dealer's silica gel sign. The use of liquid silica gel to make clothing signs has the characteristics of good feeling, wear-resisting and high production efficiency.
High temperature silica gel
The general high temperature die for silica gel mold is silica gel, which can withstand high temperature between 200~300 degrees Celsius. However, it can be used in aviation and bronzing industries for a long time at 400 to 1300 degrees, without any change in performance.
Human silica gel
Human silica gel is a liquid silica gel solidified with less hardness. It is environmentally friendly, non-toxic and has no adverse effects on human body. Therefore, it can be implanted into the human body, usually used for making artificial limbs. It can also be used to simulate characters and so on.
