Silicone rubber smell, is a normal phenomenon, not the product itself, but the production process or storage process, due to improper operation, such as: in the mixing temperature is too high, mixing time is too long, or in the vulcanization before the rubber in the impurities are not removed; In addition, when the rubber material is stored for a long time, the water evaporates, and the silicone rubber will also have some special odor.

Food grade silicone rubber has an odor, which may be due to the following reasons:

1, the problem of raw materials, poor quality of raw materials, high oil content, or other impurities, these substances will be released through high temperature decomposition.

2, the production process control is not strict, such as: mixing temperature is too high, mixing time is too long; Or the use of inferior additives, etc., will lead to unpleasant odor.

3, the storage conditions are not good, such as: long-term exposure to the air, or long-term storage in a humid environment, will make the surface of the colloidal oxidation reaction, resulting in rancid taste.

4, transportation and packaging process, affected by external factors, resulting in pollution, will also affect the quality of the product.
