Silicone resin has many characteristics, one of which is high temperature resistance, many people do not understand the reason, so why can silicone resin be high temperature resistant? Next, silicone resin manufacturers will come to answer the reasons for everyone, and follow this article to find out.
This depends on what the contrast is.
The main chain structure of the silicone resin molecule is -O-Si-O-. The silicon-oxygen bond is very stable and it is not easy to break, so it shows that the silicone resin is very stable and resistant to high temperature.
Therefore, if epoxy-modified silicone resin is compared with pure silicone resin, its heat resistance is not as good as that of pure silicone resin. If it is epoxy modified silicone resin, compared with pure epoxy resin, its heat resistance is better than epoxy resin.
We must first decompose the purpose and characteristics of the silicone resin before selecting the right silicone resin. Sihai brand silicone resin products have good electrical insulation properties. Their dielectric loss, voltage resistance, arc resistance, corona resistance, volume resistivity and surface resistivity are among the best in insulating materials, and their electrical properties are affected by The influence of temperature and frequency is small. Therefore, they are a stable electrical insulation material and are widely used in the electronics and electrical industries, especially high temperature insulation paints have been widely used.
Silicone resins have a silicon-oxygen O-Si-O bond as the main chain structure. The bond energy of the C-C bond is 82.6 kcal / gram molecule, and the bond energy of the Si-O bond is 121 kcal in silicone. / Gram molecule, so the thermal stability of the silicone resin is high, the chemical bonds of the molecules under high temperature or radiation irradiation do not break, do not decompose. Silicone resin is not only resistant to high temperature, but also low temperature. It can be used in a wide temperature range. Whether it is chemical or physical mechanical properties, the change with temperature is small.
