Silicone is a man-made rubber produced by bonding oxygen and silicon molecules. It is a man-made polymer, but instead of a carbon backbone like plastic, it has a backbone of silicon and oxygen. Silicon comes from sand and oxygen comes from air, both are plentiful resources on earth.
Silicone is reusable, eco-friendly, naturally BPA, BPS, BPF, PVC, phthalates, PFC, perchlorate and nitrate free, does not release dangerous chemicals into food and can be recycled. Silicone is not toxic to aquatic or soil organisms, it is not hazardous waste.
Silicone dishes are great alternative to plastics made from fossil fuels and containing harmful chemicals dangerous to health and environment.
The addition of fillers, colors and other chemicals have the potential to allow the harmful chemicals to migrate into your food. Poorly made silicone cookware may also leak out colors and give a bad odor.
Most silicone kitchen items are made from silicone with fillers and colors, which can compromise the quality and durability of silicone or can be dangerous to your health.
A slight yellowing of pure, unaltered and untreated silicone can happen over time with certain deep colored foods. This is a natural process and does not affect the properties of silicone. To remove the yellow coloring, add white vinegar to your wash cycle or microwave the bag with white vinegar inside it.
Be aware that phosphate-free dishwashing detergents may cause silicone dishes to end up with water spots or hold onto certain smells/tastes. It’s no big deal, just add some white vinegar to your wash cycle.
FDA Food Grade silicone is the only type of silicone approved for use in the food industry by Food and Drug Agency (FDA). It is pure, unaltered and untreated with platinum. It also means that the silicone kitchen product has been tested per FDA-required chemical tests (21CFR177.2600) in the FDA-approved chemical laboratory.
The pure FDA Food Grade silicone is defined by law in the Code of Federal Regulations Title 21 177.2600, which lists specific validated chemical tests to determine the purity of silicone by the "total extractive residues" tests using different solvents.
Only 100% pure, uncolored silicone will pass the strict chemical tests mandated by FDA. All 100 % Pure Silicone Products are Clear in Color.

During FDA testing, a small amount of silicone is dissolved in different solvent solutions. Each solvent solution is tested for the presence of anything other than silicone. If nothing other than silicone is found, it means that the silicone is 100% pure.
A common misconception is that the "pinch test" is a way to tell if the silicone has filers. However, it is not more than the urban myth. The "pinch test" is not a real scientific test and, therefore, totally unreliable. The only way to verify is to simply ask for the testing result document with the picture of the product tested.
Some manufacturers perform FDA testing on the pure silicone starting material and add colors and fillers to the kitchen product they manufacture. They do it because the FDA testing would fail for any product with colors and fillers and they are trying to hide the true content of their silicone kitchen product.
There are many different silicone product available on the market right now - with different colors, different hardness and different physical and chemical properties. It can be very confusing.
Pure silicone is a rubber-like, flexible and clear material. Some commercially available silicone products are colored, hard, inflexible and do not resemble the characteristics of pure silicone raw material.
These altered properties of silicone are achieved by curing pure silicone raw material with different chemicals and adding substances (fillers, plastics, colors, etc) to achieve desired characteristics of silicone.
However, there are no scientific studies to determine if these altered silicone products are as safe as pure silicone is.
Platinum silicone is a silicone that has been treated with platinum. The treatment of silicone with platinum changes the properties of silicone in such way that it can be manufactured at lower temperature that an untreated silicone.
Why is this needed? The main reason is to enable silicone to be mixed with plastic, since plastic cannot be manufactured at high temperatures than untreated silicone requires.
Silicone bags can be used successfully for sous vide cooking, but some adjustments have to be made due to differences between plastic and silicone.
Silicone is much heavier than plastic and much less flexible. Therefore, removing the air from the silicone bag can be tricky. It can be done by squeezing the bag with a clip attached or by using the fork tool. Typically it is not possible to completely remove the air out of the silicone bag. However, it will not cause any issues because the bag will not float due to its heaviness and the bag will absorb the expansion of a small amount of air left inside.
Another difference between silicone and plastic is that silicone is a heat conductor (the material itself will absorb heat) while plastic is an insulator that does not absorb heat. This characteristic of silicone promotes even heat distribution inside of the bag.
Silicone bags cannot be used with the commercial sealers for sous vide for a simple reason: silicone (unlike plastic) is exceptionally resistant to heat and it can withstand temperatures up to 425 F. Plastic melts at about half of that. Sous vide sealers do not generate the temperature high enough for melting of silicone.
