Silicone oil is a good liquid auxiliary that plays an irreplaceable role in many aspects. Silicone oil is also inseparable from the use of silicone rubber. Some problems are often encountered during the use of silicone rubber, and research has found that many of them are related to silicone oil. Are there only advantages and no disadvantages to using silicone oil in silicone rubber?
1. Why do mold silicone molds turn over less frequently? Answer: Too much silicone oil is added during the mold making process. The silicone oil destroys the molecular weight of the silicone, causing the mold to be less used and less durable.

2. Why does the mold silicone have poor tension? Answer: In the process of making the mold, the customer added a large amount of silicone oil in order to reduce the viscosity of the silicone and make the silicone easier to operate. This caused the silicone to become softer, less resistant to pulling, the tear strength was reduced, and the pulling force became worse.

3. Why does the silicone mold emit oil? Answer: Oil leakage from silicone molds is due to the use of compound silicone oil, which contains white mineral oil, during the production process.

4. Why are silicone rubber molds not resistant to acid and alkali and aging? Answer: We do not recommend adding silicone oil during the mold making process. If added, it must not exceed 5%. Silicone oil will destroy the molecular weight of the silicone.

5. Why is the pad printing silicone rubber head not durable? Answer: It has a lot to do with the amount of silicone oil added to the silicone rubber. The greater the amount of silicone oil added, the softer and less durable the rubber head will be.

Silicone oil will destroy the molecular weight of silica gel. Silicone rubber and silicone oil both belong to the category of silicone resin. From a structural point of view, their difference depends on the proportion of silicon atoms and groups in the molecular structure. The ratio of groups to silicon atoms in silicone rubber is close to two to one, while the ratio of groups to silicon atoms in silicone oil is greater than two to one. From the above, we can basically draw a conclusion: the higher the atomic weight of silicon, the closer it is to a solid, and the lower the atomic weight of silicon, the closer it is to a liquid (silicone oil will not condense). Many common problems are caused by adding silicone oil to change the overall ratio of silicone rubber groups to silicon atoms, thereby reducing the hardness and use times of the silicone rubber. Therefore, when using silicone oil, you must pay attention to the "amount" issue. Another thing is to choose a strong manufacturer.
