Silicone is a modern ubiquitous material, and its applications are extremely extensive. From the usual silicone pacifiers for babies, to the silicone mobile phone cases we hold in our hands, to professional prostheses used in medicine, to the separation columns used to separate various organic substances in the laboratory, silica gel plays a role in our production and life. plays a very important role.

However, many careful friends will find that newly purchased silicone appliances can smell an odor. What is this odor?

Before the liquid silicone is cured, it is environmentally friendly, non-toxic, and has no odor. But when making silicone utensils, it is time to add color masterbatch and vulcanizing agent, and then form it at high temperature through a hydraulic press. A little odor will be produced during this process, which is a normal situation. After two or three days of natural ventilation, the odor will disappear naturally without affecting the quality of silicone products. However, if the odor of silicone products is abnormally pungent, you need to pay attention. It may be that the manufacturer of silicone products has used unqualified silicone raw materials or vulcanizing agents.

If the purchased silicone products have a strong odor, we can try to eliminate the odor with the following methods:

Boil method:
That is, boil it in boiling water for 10~30 minutes, remove it and dry it, and use it in those silicone products that are water-resistant but not high-temperature resistant;

Baking method:
That is, directly bake at 200°C for 10~30 minutes, and finally clean and wipe with a clean damp cloth, and bake it to dry;

For silica gel without peculiar smell, we still recommend to use the above method once before use, which is safer. In addition, some silicone materials are thin and soft, and the manufacturer may only recommend scalding them with hot water, so try to scald them as many times as possible to promote the volatilization of residues. If you have a high-temperature steam sterilizer at home, you can also try it. Some friends will want to use ultraviolet disinfection to sterilize silicone products. However, it should be noted that when using ultraviolet disinfection, excessive ultraviolet radiation will cause the aging of the silicone and shorten the life of the silicone products.
