Food grade silica gel is made of silicic acid condensation of inorganic polymer colloidal material, the content of more than 98%, non-toxic, tasteless, stable chemical properties. Under normal conditions, it reacts with caustic and hydrofluoric acid, but not with acid-base salts. Can withstand high temperature 220℃, can be used in microwave oven, no toxic side effects on human body. Safer and healthier than other materials.

    For example, ordinary plastics need to add a lot of antioxidants, plasticizers, stabilizers, etc., in the manufacturing process.These additives are harmful to humans, and plastics can cause endocrine disruptors and fats to leak into the body.At high temperatures.It builds up in the organization.In short, food-grade silica gel has high stability and can further meet the requirements of healthy and safe life.In fact, civilian residents have found traces of food-grade silicone.Z Common washers are used to seal pressure cookers.Easy to clean, non-toxic and harmless.

    At present, the food organic silicone products on the market are mainly divided into medicinal organic silicone and food organic silicone, which must pass the certification of the State Food and Drug Administration.Baby products on the domestic market usually follow three national standards: China, the United States and Europe.At the time of purchase, experts are aware of the national standards the product is subject to and whether the product is approved by the FDA or a third-party testing laboratory to ensure authenticity.This field is mandatory.

    The rise of food silica in foreign countries has proved its health and safety properties.Domestic manufacturers are also choosing to replace the original plastic material, mainly for maternal and infant products, but some companies are using the material creatively in everyday products.As daily domestic water.Cups, bowls, baking molds, steamers.At the same time, ceramic silica gel, glass silica gel and other materials combined with other materials.It is beautiful and durable, while also emphasizing the concept of healthy living, environmental protection and hygiene.

    How to distinguish food grade silica gel?It can be distinguished by the transparency of the raw materials.Food silica gel is highly transparent, ordinary silica gel is translucent.It can also be distinguished in terms of tensile toughness.Food-grade silica gel has excellent tensile toughness and will not turn yellow even after long-term use.

    How to distinguish whether silica gel is food grade environmental protection?

    Smell? Smell is not food grade.Currently, there are two types of liquid silica gel.One is condensation (environmentally friendly, smelly, toxic), and the other is bonus (completely environmentally friendly, non-toxic, tasteless).

    Tactile sensation: Food-grade silica gel has excellent toughness and elasticity, small external deformation, feel smooth, and industrial silica gel products are easy to deform, feel rough.

    In addition, we have to distinguish, they are food grade silicone.Which is better?

    1. Comparison of tensile strength and tear strength: For example, when making a separate arm mold, the mold can be removed without the use of an external mold.Silica gel is very elastic and durable, poor silica gel even using gauze is very fragile. 

    2. Whether the low hardness silica gel is oily: you can compare the same silica gel with the Shaw A hardness of 0 degrees or 5 degrees to compare whether the surface is oily.If it is oily, it is defective.
