People often encounter some problems in the use of silicone, and many of these problems are related to silicone oil. As we all know, silicone oil is a good liquid adjuvant and plays a key role in many places, and it is also inseparable from silicone oil in the use of silicone. However, relatively, the advantages brought by silicone oil also have a negative effect on silicone products. Here are a few problems in the use of silicone:

Question 1: Why does the mold silicone have less mold turnover?
Answer: Too much silicone oil is added in the mold making process, and the silicone oil destroys the molecular weight of the silicone, which reduces the number of times the mold is used and is not durable.

Question 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 easy to operate, which caused the silicone to become soft, not resistant to pulling, the tear strength was reduced, and the pulling force became worse.

Question 3: Why does the silicone mold appear oily?
Answer: The silicone mold appears oily because the compound silicone oil is used in the production process, which contains white mineral oil.

Question 4: Why is the silicone mold not resistant to acid and alkali, and not resistant to aging?
Answer: It is not recommended to add silicone oil in the process of making the mold. If you add it, make sure not to exceed 5%, because the silicone oil will destroy the molecular weight of the silica gel.

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

There are many problems that are not listed one by one, but through the above problems, it can be generally concluded that one reason is that silicone oil will destroy the molecular weight of silica gel. If you have enough understanding of silica gel products, you will understand that silica gel and silicone oil belong to the category of silicone resins, and their difference in structure depends on the proportion of silicon atoms and groups in the molecular structure. The ratio of groups to silicon atoms in silica gel is close to 2:1, while the ratio of groups to silicon atoms in silicone oil is >2:1. Therefore, it can be concluded that the higher the silicon atomic weight, the closer to the solid, and the smaller the silicon atomic weight, the closer to the liquid (silicone oil will not condense). Many common problems are caused by adding silicone oil to change the ratio of the overall group and silicon atoms of the silica gel, thereby reducing the hardness and the number of times of use of the silica gel. Therefore, in the process of using silicone oil, we must pay attention to the problem of "quantity".

On the other hand, due to the different materials and processes of various manufacturers, silicone oil will also cause differences in product quality, and even shoddy in the market. Pay attention to these conditions when using silicone oil.
