When it comes to sealing, insulating, and protecting, silicone-based products are amongst the hardest and best performing in the industry. The two popular choices in the industry today are silicone foam gaskets and silicone sealing foam cords as both can be relied upon for high heat resistance, flexibility, and long service life as needed in some applications.

What is a Silicone Foam Gasket?

A silicone foam gasket is a sealing material manufactured from expanded silicone foam. Its attributes are that it serves as a filling agent, barrier, and a preventive medium against the leakages of air, dust, moisture, or chemicals. The compressibility and resilience of the material enable it to maintain a tight seal even under conditions of stress through various temperature changes.

Silicone foam gaskets find application in the following areas:

●  Automobile: seals engine components, lights, and doors.

●  Electronics: shields sensitive devices from dust and moisture.

●  Construction: insulation in windows, doors, and HVAC systems.

●      Aerospace: withstand extreme temperatures and vibrations.

The main advantages are heat resistance, UV stability, weatherproofing, and a low compression set which means these products maintain their shape after prolonged service.

What is a Silicone Sealing Foam Cord?

Silicone sealing foam cords are manufactured as a round and flexible strip of silicone foam. Unlike flat gaskets, they are often designed for custom fit or continuous sealing. They can be installed into grooves or cut to length and bonded together to form O-rings or circular gaskets.

These cords find applications widely in:

●  Industrial sealing, which covers pipes, tanks, and heavy machinery.

●  Food and medical equipment due to the non-toxic and chemically inert nature of silicone.

●      Outdoor enclosures where resistance to ozone, rain, and sunlight is critical.

The foam cord has good resilience so that it can return to its original shape after compression. Hence, suitable for repeated dynamic sealing applications.

For Sealing Purely Silicone Foam:

Silicone foam in the form of a gasket or cord has had its superiority over other materials mainly by a few special unique properties:

●  abstains from cracking or hardening even at very high or low temperatures.

●  resists deterioration from chemical, UV rays and ozone exposure.

●  provides a long-lasting seal without being continuously replaced.

●      able to tolerate flexibility to conform to any irregularities in shape or surface.

Final Thoughts

Gasketing using silicone foam options left right for dual versatile sealing solutions fit within different industries. Whether abiotic need the paz- through and round wiring for producing flat panels and joints or flexible cords for small application needs, silicone foam ensures reliability, durability and peace of mind.

An effective sealing material will help in improving performance, curtailing maintenance and increasing equipment longevity.
