Foamed silica gel is the most common product classification in silica gel products. At present, foamed silica gel is widely used in the automotive, aerospace, computer, mechanical and electronic industries, fax machines, and high temperature parts of printers due to its stable chemical properties, high adsorption performance, high mechanical strength, and good thermal stability; In the body of automobile machinery, kitchen appliances, household appliances and other equipment.
characteristic
1. This product has excellent heat resistant air aging performance, ozone resistance, insulation, and resistance to fuel oil and lubricating oil. It can work in air or oil media at a temperature of - 60~+250 ℃.
2. Strong sealing ability, which can effectively prevent small particles and rain.
3. Sealing, dust-proof, moisture-proof, airtight and shading, vibration isolation and fire prevention
4. Vibration isolation used in electronic equipment and vehicle interior
5. It can be used to punch all kinds of sealing gaskets and base plates with strict requirements
6. In case of moisture, water or temperature rise, the change is small. Even if the silicon dioxide generated by short circuit combustion is still an insulator, this will ensure that the electrical equipment continues to work, so it is most suitable to make wires, cables and lead wires.
