Comparison of differences between food grade mold silicone and ordinary silicone raw materials
May 18,2023 Hanast
Food grade mold silicone is actually one type of silicone rubber material. However, since it is a food grade requirement, there must be some differences between it and commonly used ordinary silicone rubber raw materials. Below are examples to illustrate the differences between the two:
What is food grade silicone ?
Food grade silicone is a colorless, odorless, and non-toxic environmentally friendly silicone rubber material with good transparency, softness, elasticity, no deformation during twisting and pulling, no cracking, long service life, poor resistance to high and low temperatures, as well as good electrical properties and tear resistance. It mainly focuses on the requirements of food properties, and meets industry standards for entry, sterilization, and other aspects. Our food grade silicone material produced by our company does not turn yellow when placed at room temperature No frost spraying, no whitening when boiled in water, no fading, no odor when left in water for a long time, and no scale formation.
Comparison between food grade silicone and ordinary silicone (precipitated silicone)
1. Different performance characteristics
Ordinary silicone rubber materials are produced using original vulcanizing agents and also have non-toxic and odorless properties. However, over time and improper maintenance of products, yellowing or dark lines may occur, while food grade silicone does not have yellowing or other phenomena;
2. Different fields of application
Ordinary silicone is mainly used in industrial products, electronics, automobiles, and electrical accessories, while food grade silicone is mainly used in fields with high safety and environmental protection requirements such as biopharmaceuticals, healthcare, daily necessities, and baby and child products;
3. Higher requirement level
Food grade silicone is reinforced on the basis of ordinary silicone materials, with no oil or dust on the surface, high requirements for vulcanizing agents, and no odor after molding. These all determine that the most fundamental material needs to choose a higher ratio performance, and rough and shoddy silicone raw materials cannot be made into high-quality products.
