Important Reasons to Use Custom Silicone Gasket Manufacturers

Many manufacturers rely on custom silicone gasket applications to protect or improve their products. In fact, silicone is one of the most popular materials today for sealing. Why is it so popular? Here are some of the good things it has to offer.

Electrical Insulation

Silicone is an excellent insulator from electricity. This is important for components with electrical or electronic needs. Even if you immerse your gaskets in water, their electrical resistance does not change. Materials protected by silicone rubber do not present shock hazards.

Fire Resistance

Many products today need high amounts of fire and flame resistance. This is important for internal combustion engine parts and applications. Marine and aerospace applications also need fire resistance and custom silicone gasket protection is vital. In fact, some products have a UL94 rating. UL94 is a special test from Underwriters Laboratory to test plastic materials response to open flames. If your products pass this test, they are safe from certain types of fires.

Chemical Resistance

Many industrial applications use chemicals, and silicone resists many chemicals. In fact, it’s often used in automotive applications where gasoline or oil can come into contact with parts. For example, silicone seals often protect mechanical fuel pumps and fuel injector parts.

Food Processing

Some types of silicone are safe for food processing equipment. Many processing plants routinely use heat and steam, and neither one affects silicone’s ability to seal and protect.


Exposing a custom silicone gasket to water has no effect on its integrity. In fact, you can submerge it in water for long periods of time with no degradation.


You can buy silicone gaskets made from foam, rubber, or sponge foam.

Cold Resistance

Silicone doesn’t shrink or crack when exposed to low temperatures. This makes it perfect for weather-stripping and outdoor applications. It also keeps its flexibility properties in both hot and cold environments.
