Product use: Mainly used for a mask line to slide and adjust the length of the mask line to make the mask wear tight

Product material attributes: processed works with silica gel as the main raw material are all called silica gel products. Silica gel is a porous material with different particle sizes formed by proper dehydration of silicic acid gel. It has an open porous structure and can adsorb many substances. It is a good desiccant, adsorbent and catalyst carrier. The adsorption of silica gel is mainly physical adsorption, which can be regenerated and used repeatedly. Add acid to the alkali metal silicate (such as sodium silicate) solution to acidify it, and then add a certain amount of electrolyte to stir to form a silicic acid gel; or add acid or Ammonium salts can also generate silica gel. Let the silicic acid gel stand for a few hours to age it, then wash it with hot water to remove the soluble salts, dry it at 60-70℃ and activate it at about 300℃ to obtain silica gel.The silicic acid gel is soaked in cobalt chloride solution and then dried and activated to obtain discolored silica gel.

Food-grade silica gel is non-toxic and tasteless, insoluble in water and any solvents, and is a highly active green product. Food-grade silica gel has inherent thermal stability (-40°C-230°C). It is suitable for different occasions. The product has good flexibility and meets different needs.

Features

High temperature resistance: applicable temperature range -40 to 230 degrees Celsius, can be used in microwave and oven.

Easy to clean: The silica gel products produced by silica gel can be cleaned after being rinsed in clean water, and can also be cleaned in the dishwasher.

Long life: The chemical properties of silica gel are very stable, and the products made have a longer life than other materials.

Soft and comfortable: Thanks to the softness of the silicone material, the cake mold products are comfortable to the touch, very flexible and not deformed.

Variety of colors: different beautiful colors can be deployed according to customer needs.

Environmental protection and non-toxic: no toxic and hazardous substances are produced from the raw materials entering the factory to the finished product
