Shaped silicone ring Dongguan City Hengli Hang Yawei printing equipment firm silicone material chemical composition and physical structure of silicone products plant, determines that it has many other similar material was difficult to replace characteristics: high adsorption properties, good thermal stability, and chemical properties stability, high mechanical strength and the like. Silicone divided according to their pore size: large pore silica, coarse pore silica gel, B-type silica gel, silica pores. Silicone Dongguan Hengli printing equipment materials firm Yawei constant low temperature resistance: ordinary rubber critical point is the lowest temperature of -20 degrees to -30 degrees, however silicone rubber is -60 degrees to -70 degrees, still has good elasticity Some specially formulated silicone rubber can also withstand very low temperatures as low ring. Conductivity: When adding conductive filler such as carbon black silicone rubber will have a good electrical conductivity such as a keyboard electrically conductive contact point heating element member antistatic shielding the high-voltage cable with a conductive film and so on for medical treatments.
