Because silica gel is relatively stable and highly absorbent, it is used in many fields, but some people will smell some unpleasant smells during use, which has a lot to do with some of the raw materials. Of course there are other factors.

Silicone smell reason:
1. Silicone products custom manufacturers introduce silica gel is an amorphous substance, its chemical formula is mSiO2 · nH2O. It is insoluble in water and any solvent, non-toxic and tasteless, and has the same chemical properties. It does not react with any substance except strong alkali and hydrofluoric acid. Silicone is not odorous, but the smell is mostly the use of silica gel raw materials, and the volatilization agent volatilizes the smell.

2, the cause of silicone odor: the impact of individual inspection standards, unless the customer proposes extraordinary inspection standards: silica gel profile process product rubber wear> 500 times, RCA> 3-6 detection interval is 20-30cm, time is 5s detection The status is that the inspection surface is 45° with the table top, and the height of the rotation is 15°. The plastic product profile product RCA>200-300 times has a power of >4B (5%).

3, the production process is not like this: according to the customer sample to open the mold - according to the color hardness of the sample, such as color mixing - hydraulic forming - silk screen profile color varnish - spray paint overview (spray hand oil, spray PU) - Quality assurance - shipping, if not, will produce some errors, and then there will be odor.

In order to eliminate the odor, we can soak the silicone products in boiling water for 2-3 hours, and most of the taste can be dispersed. After two or three days in natural ventilation, the smell will naturally disappear and will not affect the quality of the silicone products. If you are a customer who needs to be customized, you can use the platinum vulcanizing agent directly before making the product to ensure that there is no odor at all.
