Second, the performance introduction:
Heat resistance, cold resistance, thick with temperature change small, good waterproof performance, can form a waterproof film on the surface of the object, good chemical stability performance, can form a waterproof film on the surface of the object, chemical stability, except for aluminum, strong acid, strong alkali has no effect on general metals and chemicals, physiological inertness is no drugs.
Third, the application introduction:
The product has excellent electrical insulation, widely used in the filling of semiconductors and transistors, the anti-fouling flashover of high-voltage insulators and the insulation of the surface of the instrument, and is suitable for the insulation and protection of rubber parts of cable connectors and battery terminals. It has good lubrication and sealing for metal and plastic, rubber connection, that is, vacuum system. The refined silicone paste is used for sealing high vacuum units and can maintain a high vacuum of 1.33×10-4 pa with durability. In addition, the products are also widely used in the optical field, such as the filling of optical fiber cores and the sealing of optical cable joints. In the field of optics, it is used for optical coupling, internal reflection and reflection of anti-R-ray cameras and scintillators, axial lubrication of optical instruments, plastic demolding, rubber demolding, antifoaming, etc.
