Silica gel is a kind of natural environmental protection non-toxic and harmless material, widely used in many fields.Silica gel is divided into ordinary silica gel, medical grade silica gel, food grade silica gel, high transparent silica gel, high tensile silica gel and so on.Today the grand plan is to say what is food grade silica gel.
Food grade silica gel in silica gel mold: can be used for automobile parts, military material parts, aerospace material mold, resin handicraft mold, automobile tire mold, yacht mold, chocolate mold, cake mold and so on.
Food grade silica gel in silica gel products: can be used to do silica gel prosthetic limbs, silica gel chest paste, silica gel mask, silica gel baby, silica gel washer, adult supplies, simulation food, simulation vegetables, medical grade products, etc..
Characteristics of food grade silica gel: Mold shrinkage of small food grade silica gel temperature range under - 65 ° C to 350 ° C can be used for a long time and keep its soft elastic function, has excellent function of electric and chemical stability, water resistance, ozone resistance, resistance to weathering, non-corrosive, physiological languid is lazy, avirulent insipidity, line shortening rate is low, the product high clarity, demoulding good strength, easy to operate and so on characteristics.
Food grade silica gel storage and precautions:
1, the goods are non-dangerous goods, sealed storage, placed in a cool place, avoid rain, sunlight exposure, storage period of half a year.
2. Mixing with the compound of condensed silicone rubber, sulfur, phosphorus and nitrogen should be prohibited in the use of commodities, otherwise it will affect the vulcanization of the rubber. If the mold of condensed type has been used, it must be cleaned with gasoline, otherwise the mold appearance can not be vulcanized or sticky.
