Knowledge Base

Silicone Gasket has outstanding high and low-temperature resistance, working in the temperature range of -70℃ – +260℃ to maintain good elasticity, and having the advantages of ozone resistance, and weathering resistance. A silicone gasket is suitable for thermal machinery. Silicone gaskets, without any toxicity, can be used to make thermal insulation, insulating products, and medical rubber products. At the same time, silicone gasket still has the properties of waterproof, electrical conductivity, wear resistance, and oil resistance, which is widely used in machinery, electronics, plumbing, and other industries.

There are thousands of materials to make gaskets with, silicone is prominent among them. Why use silicone to make a gasket? Because:

(1) Well-Performed Insulation

Silicone gasket is an expert at insulating electricity. By combing silicone with silver-plated aluminum particles, a silicone gasket can blockade the EMI (Electromagnetic Interference) for its conductive ability. Therefore, silicone gasket is widely used in electronic equipment.

(2) High Durability

The silicone gasket is very durable. They can be strongly resistant to ozone, UV light, and extreme weather conditions. The benefit makes silicone gaskets a top choice for outdoor use.

(3) FDA Certification

Because silicone gasket is under the list of FDA certification, so silicone gasket can be used in health care equipment, medical devices, and food processing factories. Also, the silicone rubber gasket is physiologically inert. That means that silicone rubber gasket is non-toxic and harmless.

(4) High and Low-Temperature Resistance

Silicone rubber gasket sticks to work at a temperature of up to 392 degrees Fahrenheit. Therefore, it is a great component in many industrial applications. Even exposed to high temperatures, silicone rubber gaskets will not wear out or degrade.

(5) Pressure Confrontation and Flexibility

Silicone rubber gasket can work well under intense pressure. The thickness and shape of the silicone rubber gasket will turn back even after being pressed for a long time.

Yes,  silicone gasket is better than rubber gasket.

Natural rubber and silicone are two common materials applied to manufacture silicone rubber gaskets. In some condition, silicone is more efficient and work better than rubber.

A rubber gasket can work well in temperatures from -58 to 176 degrees Fahrenheit. While silicone gaskets can handle more extreme temperatures from -58 degrees to 446 degrees. At the same time, the rubber gasket cannot be used with ozone, acid, oil, and grease, while a silicone gasket can use with these materials.

Choosing the suitable material and gasket hardness is crucial. Our knowledgeable team can assist in advising which will fit your applications.
