- Flexibility and Durability: Silicone is highly flexible and durable, allowing it to conform to various shapes and withstand repeated use.
Hygienic Properties and Easy Cleaning
Food grade silicone is non-porous and resistant to bacteria growth, making it hygienic and easy to clean. Its smooth surface prevents food particles from adhering, and it can be sterilized in boiling water or a dishwasher, ensuring optimal hygiene.
Manufacturing Process
Food grade silicone is a type of silicone that is specifically designed for use in food applications. It is made from a high-purity silicone polymer that meets the requirements of the FDA and other regulatory agencies. The manufacturing process for food grade silicone is complex and involves several steps.
The first step is to create a silicone polymer. This is done by reacting a silane monomer with a catalyst. The reaction is typically carried out in a solvent, such as toluene. The resulting polymer is a long chain of silicone atoms with alternating silicon and oxygen atoms.
The next step is to cross-link the polymer. This is done by adding a cross-linking agent to the polymer. The cross-linking agent reacts with the polymer chains to form a network of covalent bonds. The cross-linking process makes the polymer stronger and more resistant to heat and chemicals.
Once the polymer is cross-linked, it is ready to be processed into food grade silicone products. There are two main methods used to process silicone: extrusion and molding.
Extrusion
Extrusion is a process in which the silicone polymer is forced through a die to create a continuous profile. The profile can be any shape, such as a tube, a sheet, or a rod. Extrusion is a high-volume process that is used to produce a wide variety of food grade silicone products.
Molding
Molding is a process in which the silicone polymer is poured into a mold and then cured. The mold can be any shape, and the resulting product will have the same shape as the mold. Molding is a low-volume process that is used to produce custom-shaped food grade silicone products.
Regardless of the processing method used, food grade silicone products must meet the same stringent quality standards. These standards include:
- The silicone must be free of impurities.
- The silicone must be non-toxic.
- The silicone must be resistant to heat and chemicals.
- The silicone must be durable and long-lasting.
Food grade silicone products are used in a wide variety of food applications, including:
- Baking mats
- Cooking utensils
- Food storage containers
- Medical devices
Food grade silicone is a safe and versatile material that is used in a wide variety of food applications. It is important to choose food grade silicone products that meet the appropriate quality standards to ensure that they are safe for use.
