Characteristics and uses of foamed silicone, foamed rubber seals
Foamed silicone is one of the most common product categories in silicone products. At present, foamed silica gel is widely used in automobiles, aerospace, computer, mechanical and electronic industries, fax machines, and high-temperature parts in printers due to its stable chemical properties, high adsorption performance, high mechanical strength, and good thermal stability; automotive machinery In the body, kitchen utensils, home appliances and other equipment.
Features:
1. This product has excellent heat-resistant air aging performance, ozone resistance, insulation, and resistance to fuel oil and lubricating oil, and can work in air or oil media at temperatures of -60~+250℃.
2. Strong sealing ability, can effectively prevent tiny particles and rain.
3. Sealed, dust-proof, moisture-proof, air-tight and shading, vibration isolation, fireproof
4. Vibration isolation used in electronic equipment and vehicles
5. It can be used to punch all kinds of sealing gaskets and backing plates with strict requirements
6. When exposed to moisture or water or the temperature rises, the change is small. Even if the silicon dioxide generated by short-circuit combustion is still an insulator, this ensures that the electrical equipment continues to work, so it is most suitable for making wires, cables and lead wires.
The main purpose:
Suitable for heat transfer printing equipment, mechanical seals, medical equipment and other industries. It can solve the supporting needs of some national defense, military, and civilian industries. It is suitable for electronic appliances, mechanical seals and other industries. It can be used for pressing, shock absorption, and can be used for a long time without cracking. It can be die-cut into sheets of any shape according to different requirements of customers, and glue can be prepared.
Foamed rubber seal
Foamed rubber sealing strip is widely used in automobile, aerospace, computer, mechanical and electronic industries, dust collector equipment, dust collector equipment, cement plant cover, mining equipment, door seals, fax machines, high temperature parts in printers; automotive machinery body interior, kitchen utensils, home appliances and other equipment.
Performance characteristics of foam rubber sealing strip:
1. Environmental protection and safety, good insulation, high temperature resistance, small compression deformation and strong resilience;
2. Smooth surface and uniform foaming density;
3. Acid and alkali resistance, anti-aging, non-toxic;
4. Good surface non-sticky, good air permeability;
5. Using 100% high-quality silicone raw materials, and after strict testing, in line with environmental requirements.
6. The back tape can be self-adhesive, with better sealing performance, and the high temperature resistant adhesive will not fall off after long-term use. Ozone resistance of black rubber foam seals - EPDM is known as "non-cracking rubber", and has good ozone resistance among general-purpose rubbers.
Better thermal stability. Excellent aging resistance - can be used for a long time at 130 ℃, and can be used for intermittent or short-term use at 150 ℃ or higher temperature.
Weather resistance of rubber foam seals - refers to the aging of the comprehensive factors of light, heat, freezing, wind, rain, ozone and oxygen in the atmosphere in the natural environment.
Chemical resistance: Due to the chemical stability and non-polarity of the foam rubber seal itself, it does not react chemically with most chemicals, and is incompatible or has little compatibility with polar substances. It is resistant to alcohol, Acids (formic acid, acetic acid) strong bases, oxidizing agents (such as H2O2, HCLO, etc.), detergents, animal and vegetable oils, ketones, some fats, hydrazine. 3. Excellent water resistance, overheating resistance and water vapor resistance: water is a strong polar substance, and EPDM rubber is a kind of macromolecular alkanehydrazine with "hydrophobicity". There is no chemical interaction between the two, so it has excellent water resistance, overheating resistance and water vapor resistance.
