Silicone tableware customization manufacturers introduce the differences and common applications between food grade silicone and general silicone

With more and more attention paid to food safety and the epidemic has greatly changed people's eating habits, there are more and more silicone environmental protection tableware bags to replace disposable plastic products. Although we have constantly emphasized the non-toxic and safe characteristics of silicone in the previous articles, we will still use different ingredients according to specific product uses and relevant certification procedures. Today, let's talk about the difference between food grade silicone and ordinary silicone, and how to distinguish whether silicone is food grade or not.

What is food grade silicone?

Is food grade silicone edible? Of course not! Once again, we emphasize the concept that silicone is indeed a safe, non-toxic and harmless raw material for human body. Even so, it can be divided into food grade and ordinary grade. Food grade silicone generally refers to all products that will come into contact with our diet, such as baby pacifiers, straws, food containers, tableware and so on. Ordinary grade silicone is generally used for industrial purposes and cannot be used in this kind of food related products.

Differences between food grade silicone and ordinary silicone

Manufacturing method and procedure

Imported raw materials are generally used for food grade silicone, and the quality has been determined at the beginning of raw material selection. Therefore, relevant quality inspection reports are indispensable when purchasing raw materials. This is not to say that the quality of ordinary silicone is not good, but that there are different application fields between the two. Ordinary silicone products are produced by mixing ordinary silicone, while food grade products with high quality requirements are made of food grade vapor phase adhesive. We know that silica is one of the main components of silicone, and the purity density of fumed silica is higher than that of ordinary silica, so it will be different in the finished products. However, the difference between the two is not big, mainly in the tensile strength. Food grade silicone has reinforcing effect on tensile properties, so there will be no whitening in the tensile process. Therefore, it is from this point that we want to preliminarily identify whether silicone products are food grade.

Component

silicone for food is an inorganic polymer colloidal material made by polycondensation of silicic acid. It is non-toxic, tasteless and has stable chemical properties. Under normal conditions, it does not react with any acid, alkali or salt except caustic soda and hydrofluoric acid. It can withstand the high temperature of 220 ℃, so it can be put into the microwave oven and has no effect on the human body. Compared with other materials, it is safer and healthier. Food grade silicone has strong stability properties and is more in line with the requirements of healthy and safe life.

Authentication

Food grade silicone rubber products are silicone products processed from food grade silicone rubber raw materials. According to the market demand, it shall meet the environmental protection testing requirements of NSF, FDA, Rosh, rech and so on.

What is FDA?

FDA is the English abbreviation of the U.S. Food and drug administration. It is an international medical audit authority. Authorized by the U.S. Congress or the federal government, FDA is the highest law enforcement agency specializing in food and drug administration. FDA is a monitoring agency of government health regulation composed of doctors, lawyers, microbiologists, pharmacologists, chemists, statisticians and other professionals committed to protecting, promoting and improving national health. Food, drugs, cosmetics and medical devices certified by FDA are safe and effective for human body. In nearly 100 countries such as the United States, only materials, devices and technologies approved by FDA can be commercialized for clinical application.

Common application of silicone in food

Tableware

Food grade silicone is a kind of environmental protection silicone, which is non-toxic, odorless and high transparency. It is suitable for environmental protection lunch boxes, bowls and chopsticks, bags and straws containing food.

Baking and cooking utensils

Food grade silicone is soft, elastic, resistant to kink, no deformation, no cracking, long service life, cold and high temperature resistance, so it is widely used in food mold, such as chocolate mold, candy mold, kitchen cooking utensils, spatulas, clamps and so on.

Infant products

Food grade silicone will not turn yellow when placed at room temperature. It will not spray cream, spit white or fade. There is no scale and peculiar smell in the water for a long time. Generally, the common baby pacifier and milker are made of food grade silicone.

Summary

I believe that in many industries, the importance of material selection has certain differences in product quality and performance in all aspects. The source of YCS silicone raw materials is compliant, and the raw material property table and relevant test report are attached as endorsement. If there is a problem or demand, please contact YCS!
