Is liquid silicone toxic? Is it safe?

Because of its environmental protection, liquid silica gel is used more  more widely in modern industry  daily necessities. The corresponding silicone glue that uses liquid silicone rubber as the basic material has also been widely used. When using liquid silicone, customers are very concerned about whether the silicone is poisonous  is it safe to use liquid silicone? This question cannot be answered with a unified answer. The editor will lead you to discuss liquid silica gel separately below.

First, let’s look at the basic components of liquid silica gel. Its composition includes silicone oil, silica, silane coupling agent, hydrogen-containing silicone oil, platinum catalyst,  organotin catalyst. Except for the organotin catalyst, the other components are non-toxic. Liquid silicone organotin has a certain degree of neurotoxicity  is harmful to the human body, but the dosage is very small, with a unit of 1/10,000. Currently, the EU has no directive prohibiting its use.

Let us take a look at the substances released after the reaction of liquid silica gel. Addition-type silica gel has no volatile release. Common condensed silica gels release substances such as acetic acid, methanol,  ethanol. Acetic acid is vinegar  ethanol is wine. It is edible  harmless. There are ketoximes, acetone  other gases. Methanol, ketoxime, acetone, etc. are close to harmless  have a small amount of harm. Friends who are interested can Baidu themselves. We can identify the specific appendages by the smell. It should also be noted that these appendages are produced in small quantities  are discharged in the form of gas.

the above content, we can see that liquid silica gel is basically harmless, but it should be noted that there are situations in which to dilute the liquid silica gel, so that the silica gel has a better use effect  also reduces the cost. Sometimes a large amount of solvent is added to liquid silica gel,  sometimes the amount of solvent is much larger than that of silica gel. However, because the effective ingredient is silica gel, we still call this mixture silica gel at this time. The most commonly used silica gel solvent is xylene, which is a common industrial solvent, which is slightly toxic. Because xylene is flammable, it will be packed in iron cans. Xylene has a strong pungent odor. For the safe use of xylene, you can Baidu yourself.

Based on the above, we can see that most liquid silica gels can be said to be non-toxic. Only the flammable liquid silica gel that smells pungent  flammable is toxic due to the addition of xylene  other solvents.
