The structure of silicone rubber is a common problem. The products of foreign silicone giants have already had a good solution, while the domestic ones are not only lacking in basic research, but also because the concept of Chinese manufacturers is different from that of other giants, they always want to do something "magic oil", which can be solved simply, conveniently and at low cost by adding a little bit.


I have thought about this myself, that is, to develop an effective auxiliary agent, hoping to solve this problem and make some quick money by selling auxiliary agents. Therefore, in 2010, I posted a help post on the forum: How to quickly test the structure of rubber mix? He has received warm help from many friends. Later, it was found that many people have structural rapid testing requirements for silicone rubber.


After a lot of efforts, so far, the so-called "divine oil" has not been found. Later, I turned my attention to the treatment of white carbon black. Therefore, we have a deeper understanding of the structural phenomenon of silicone rubber.


In my opinion, silica leads to the structure of silicone rubber, which is mainly based on the hydrogen bonding between silica and high molecular weight polysiloxane. This conclusion has long been reached. I just added two words "huge amount".


The contribution of silica to the thixotropy of silicone rubber (including coating systems in coatings) is mainly based on the interaction between silica and silica.
