1. Heat resistance and cold resistance are very good. It can be used for a long time at -60 ~ 250 ° C. 2. Oxygen resistance. Good sky resistance 3. Good electrical performance
Silicone is a colloidal substance with solid characteristics, and its basic feature is silica (SIO2). The physical structure of silicone has abundant micropores and strong ratio surface, and its surface is a silicon hydroxyl structure. Therefore, it has strong adsorption and selective adsorption and separation ability for water vapor or other polarized substances. . Pure. High -purity production and other fields have been widely used. Silicone can be used as a catalyst or catalyst in the chemical engineering industry.
Due to the characteristics of its chemical composition and physical structure, silicone has the following advantages in the application:
1. Stable chemical properties, except for hydrofluoric acid (HF), except for strong alkali, insoluble in any other solvent and solution.
2. Good thermal stability. A fine-grained silicone can be used for other types of silicone at 300 ° C. It can use the high temperature environment for a long time at 500-600 at a temperature of 500-600;
3. Silicone has the rigidity of the osteogenesis, with good wear resistance and tensile strength.
Each of the silicone product series has its own characteristics, because silicone can obtain different types of pore structures and adapt to different application areas by controlling the corresponding process conditions.
