Silicone Parts Main raw materials

Silica gel is a granular, glass, porous form of silica prepared from synthetic sodium silicate. Silicone is tough and harder; more solid than ordinary household gel-like gelatin and agar. It is a natural mineral that is refined and processed into any form of granules or beads. As a desiccant, it has an average pore size of 2.4 nm and has a strong affinity for water molecules.

Silicone gel in the daily life of the most commonly encountered a small (usually beads 2 × 3 cm) file package. In this form, it is used as a desiccant to control the local humidity to avoid damage to some cargo or degradation. As the silicone can add chemical indicators, and absorb moisture is very good, silicone bags usually bear the user do not eat the contents of the warning. Silicone as the main raw material processing products, are known as silicone products. Silica gel is a porous material whose particle size is different from the proper dehydration of silicic acid gel. With an open porous structure that can adsorb many substances, it is a good desiccant, adsorbent and catalyst carrier. Silica gel adsorption is mainly physical adsorption, can be recycled and repeated use. In the alkali metal silicate (such as sodium silicate) solution by adding acid, acidification, then add a certain amount of electrolyte to stir, that is, the formation of silicic acid gel; or in the thick sodium silicate solution to add acid or Ammonium salts also produce silicic acid gels. The silicic acid gel was allowed to stand for several hours to age, and then the soluble salts were washed with hot water, dried at 60-70 ° C and activated at about 300 ° C to obtain silica gel. The silicate gel is impregnated with cobalt chloride solution and then dried and activated to obtain color-changing silica gel.

Food grade silica gel is a non-toxic and tasteless, insoluble in water and any solvent, is a highly active green products. Food grade silicone with inherent thermal stability (-40 ℃ -230 ℃). For different occasions. Products with good flexibility to meet different needs.

Feature editing

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

Easy to clean: Silicone gel products produced after silica gel can be rinsed with water can be cleaned, can also be cleaned in the dishwasher.

Long life: silicone chemical properties are very stable, made to make the product, compared with other materials have a longer life.

Soft and comfortable: thanks to the softness of silicone materials, cake mold products feel comfortable, very flexible, no deformation.

Color and diverse: according to the needs of customers, the deployment of a different beautiful color.

Environmental non-toxic: from raw materials into the finished product to the finished product shipments do not produce any toxic and hazardous substances.
