What are the characteristics of silica gel?

1. Heat resistance: applicable temperature range - 40 to 230 ℃, which can be used in microwave oven heating and household oven

2. Easy to clean: silica gel products produced by silica gel can be repaired and cleaned in cold water or in the sink dishwasher

3. Long service life: the organic chemical properties of silica gel material are very stable, and the goods made have a longer service life than other raw materials

4. Soft and comfortable: thanks to the flexibility of silica gel raw materials, birthday cake mold products feel comfortable, flexible and deformation free

5. Various colors: different bright colors can be made according to the needs of users

6. Environmental protection and non toxicity: no harmful substances will be caused from the arrival of raw materials to the delivery of finished products

7. Insulation characteristics: silicone rubber has high resistance, and its resistance value can still be maintained for a long time in a wide temperature range and frequency range. At the same time, silica gel has very good resistance to high-voltage arc discharge and arc discharge, such as high-voltage insulator, TV high-voltage cap, household appliance parts, etc.

8. Low temperature resistance: general plastics are rarely used. The temperature zero boundary point is - 20 ° to - 30 ° C. However, silicone rubber still has good ductility from - 60 ° to - 70 ° C. some silicone rubber with unique components can also bear extremely low temperature, such as ultra-low temperature sealing ring.

9. Conductivity: when adding conductive filler (such as carbon black), silicone rubber has good conductivity, such as conductive contact surface of computer keyboard, electrothermal material components, anti-static components, shielding of high-voltage cable, medical acupuncture and physiotherapy conductive film, etc.

10. Weather resistance: General Plastics dissolve rapidly under the action of ozone caused by arc discharge, while silicone rubber will not be harmed by reactive oxygen species, and its mechanical properties will only change slightly under ultraviolet light and other climatic conditions for a long time, such as rubber seals for outdoor applications.

11. Heat transfer: when some heat transfer fillers are added, silicone rubber has good heat transfer performance, such as radiator, heat transfer sealing gasket, printer, fax machine heat transfer roller, etc.

12. Radiation protection: the radiation resistance of silicone rubber with phenyl is further improved, such as electrically insulated cables, RF connectors for nuclear power plants, etc.
