Is the plastic cork of thermos bottle carcinogenic and toxic?

Hot water bottles used at home are generally wooden stoppers, and now many plastic stoppers of hot water bottles are plastic. People are worried that plastic products are not safe to use and will produce harmful substances that will cause harm to people. So is the plastic stopper of thermos bottle carcinogenic and toxic?

At present, the plastic bottle stopper of thermos bottle is generally made of silica gel and plastic, which makes users safer and resistant to high temperature. The quality of plastic bottle stopper is food grade, and the quality inspection is up to standard. But many inferior products are unqualified. For example, when using plastic, or when drinking water, it is found that water has the taste of plastic, so there may be harmful components, so it is not recommended to use it.

Plastic plugs made of silica gel and plastic are easy to age and will turn yellow and brittle after being used for a long time. After the plastic plug is aged, the sealing and heat preservation ability will become worse, and after it becomes brittle, particles may fall into the water, which is not conducive to people's drinking.

If you go to a regular supermarket or shopping mall to buy thermos bottles and buy brand thermos bottles, the quality is guaranteed, and normal use will not produce substances harmful to your health. I suggest that when you buy thermos bottles, don't go to small shops outside, but buy products with good quality, which will be safer and more reassuring to use.
