different materials
Phone cases, button films, and other phone accessories are often made of silicone. The main goal of these materials is to make the phone feel soft, protect it from drops, and last a long time. During the production process, this sort of silicone may have had some touch-enhancing or colouring compounds added. These are generally acceptable for people to touch, but they may not be safe for direct contact with food or drinking water.
Food grade silicone is usually utilised in situations where it touches the body directly, including in medical devices, food preparation, or storage. To make sure that the raw materials are safe, they must fulfil high safety standards like FDA or LFGB certification. This means that they must not be toxic, smell bad, or have heavy metals or hazardous compounds in them. The technique of making food grade silicone and the recipe are stricter, with a focus on purity and tolerance to high temperatures.
safety requirements
Silicone for cell phones is mostly concerned with how long it lasts, how well it resists tearing, and how flexible it is. It doesn't have to be certified for food contact and doesn't have strict rules about what chemicals it can contain.
Food grade silicone needs to be certified by an international or national food safety organisation. This includes thorough testing for heavy metals, plasticisers, volatile organic compounds, and other dangerous elements to make sure they won't be released when the silicone is used for a long time or at high temperatures. Food grade silicone is safe and can handle high temperatures, acid and alkali, and oil and fat. This makes it perfect for use in food processing or drinking water contact situations.
Differences in Things
Silicone for mobile phones puts greater focus on how it feels in your palm and how well it protects. You can change the hardness, elasticity, and colour of the product to meet your needs, but it can't resist high temperatures or chemicals as well. Softening, ageing, or impurity precipitation can happen when something is left in high heat or chemicals for a long time.
Food-grade silicone is known for being able to withstand high and low temperatures, chemicals that can corrode it, and long-term stability. It can usually handle temperatures from -40 to 200 degrees Celsius or even more, which keeps it working well when food is being processed, baked, or disinfected.
Different situations apply
Silicone for phones is mostly used to make phone cases, data cable covers, phone accessories, and protective pieces for some electrical gadgets. The major goals are to make them feel good, keep them from falling, and look good.
Food grade silicone is safe to use when kitchen tools, bottles, drinking pipes, baking moulds, food delivery pipes, and other things come into direct contact with food or water. It can also be employed in fields like medical devices and medication delivery pipes where safety is particularly important.
The disparity between price and cost
Food grade silicone is normally more expensive than regular silicone used in cell phones since it has a greater purity and stricter production regulations. Food grade silicone, on the other hand, needs more testing, certification, and quality control during production, which raises its price on the market. Silicone for cell phones is cheaper and can be changed in colour and hardness to fit the needs of the device, but it doesn't fulfil the safety regulations for food grade silicone.
