FDA silicone is a type of silicone named after its grade level. FDA is the abbreviation for the Food and Drug Administration. It is certified by the FDA for products such as food, drugs, cosmetics, and medical devices, and is globally recognized as an effective and safe product for the human body. It is a global standard proof of product quality and effectiveness.
With the rapid development of the food and medical industries, FDA silicone is becoming increasingly widely used, including milk bottle silicone straws, medical silicone, platinum silicone, etc; Also known as FDA silicone, FDA adhesive, FDA silicone, FDA silicone rubber, FDA Silicone.
FDA: Food and Drug Safety Regulations of the United States.
1. FDA Introduction:
The US Food and Drug Administration (FDA) is responsible for regulating food contact materials, which must be tested to ensure they meet food contact safety standards. Chapter 21 of the US Federal Regulations (CFR) specifies such materials and considers them as "indirect food additives".
2. The US Food and Drug Administration (FDA) lists three types of food additives:
(1) Direct food additives: ingredients directly added to food;
(2) Secondary direct food additives: adding food ingredients during food processing, such as using ion resins, dissolving and extracting to treat food;
(3) Indirect food additives: Substances that may come into contact with food as part of packaging or processing equipment, but are not directly added to food;
Note: Only 'indirect food additives' are related to food contact materials.
3. FDA testing items for materials in contact with food:
Food contact materials required by US Federal Regulations (CFR): 21 CFR Sections 174-190; Important chapters include:
(1) 21 CFR Section 175 Indirect Food Additives: Additives and Components of Coatings
(2) 21 CFR Section 176 Indirect Food Additives: Paper and Board Composition
(3) 21 CFR Section 177 Indirect Food Additives: Polymers (Plastics)
FDA certified food grade environmentally friendly silicone features:
1. Has excellent high-temperature resistance, with temperatures ranging from 300 to 500 degrees;
2. Food grade, non-toxic and odorless, reaching edible grade;
3. No shrinkage, high precision. It can solve the problem of products that cannot be produced by film pressing machines, filling the gap in the production of large lead-tin alloy skills and precision products with stripes. It is currently the leading HTV-2 high-temperature adhesive in China, and also the preferred material for producing lead-tin alloy skills and precision molds;
4. High tensile strength, tear resistance, and multiple mold turns;
6. Good fluidity and easy perfusion; It can be cured at room temperature or at elevated temperature, making it easy to operate;
7. Low shortening rate, no low molecules are released during the crosslinking process, so the volume remains unchanged, and the shortening rate is less than 0.1%.
