Food grade silica gel is a kind of liquid silica gel, belonging to platinum sulfide silica gel, AB two components, one to one ratio.Molding food grade silicone is composed of hydrogen silicone oil, vinyl silicone oil, 107 base glue, platinum catalyst and other main raw materials, so the quality of these basic raw materials, also directly affects the cost of food grade silicone.

    Silicone oil this type of material in the market quality is good and bad, there are imported Dow Corning silicone oil, Xinyue silicone oil, wacker silicone oil;Domestic silicone oil also has spark silicone oil, Xin 'an silicone oil, and some small factories refine their own silicone oil. 

    So is food-grade silicone cheap?

    Each manufacturer produces different quality, different materials and different prices.Generally made of food grade silica gel cracking material, material price is low, the cost is low, but to produce silicone quality is very poor quality, when the silica gel after curing, take it's easy to have a sticky oil, Z is serious with waste rubber recycling of silicone oil with mild pungent taste, cannot achieve the standard of food grade certification, therefore cannot be used to produce food silicone mold.

    With a new good material to do food grade silica gel, when the silica gel is fully cured, the tear strength and surface effect will be very good.Therefore condensed industrial grade liquid silica gel price is cheaper than food grade silica gel price.The price of molded silica gel is higher than that of condensed silica gel because the cost of platinum catalyst is high.The same hardness and performance of silica gel, plus forming liquid silica gel than condensation liquid silica gel unit price of 20-30 yuan /KG difference.Therefore, only customers with environmental protection requirements will use molded silica gel to make molds.
