General Properties and Applications of Felt Gaskets

26 July 2022

Leaks can be devastating for many equipment pieces, machines, and appliances. They can even ruin system components found in most properties.

To ensure that these issues will be mitigated, one should invest in quality gaskets. Gaskets are mechanical seals that can fill any spaces between mating surfaces. Since spaces are sealed, any instances of leaks are typically mitigated. They can also ensure that the mating surfaces will stay intact even under varying operating conditions.

The materials used for gaskets, however, can only be effective in specific cases. Using the wrong materials will only lead to more issues. Therefore, users like you should know the elements found in the surroundings of your devices or equipment pieces.

The Properties of Felt Gaskets 

One material you may want to consider in your property or site is felt. Felt is comprised of natural and synthetic materials like wool, rayon, and acrylic. What is great about this material is it is not only useful for gaskets, but it can also be utilised for architectural components intended for sound and vibration dampening. Felt can even be used for decorative purposes, enhancing the appeal of properties. 

As for gaskets, felt can be effective in sealing equipment pieces and system components due to its high strength. Felt gaskets can likewise insulate sound, resist tearing, and withstand flame. Other qualities of felt gaskets include excellent thermal insulation and being environmentally friendly.

Different types of felt materials can be utilised in making gaskets. These materials include wool felt and synthetic felt. Wool felt comes from premium wool fibres that are created through wet processing. Gaskets out of this material can boast good chemical resistance and retain their original form. Synthetic felt gaskets, alternatively, are created by combining polyester and other artificial fibres through heat or a needle punch process. These gaskets have high mildew and wear resistance.

Felt Gaskets Key Applications

Felt gaskets can be primarily utilised in two applications.

One of the applications of felt gaskets is to dampen sound or any noise. Felt material, as mentioned earlier, is known to be durable and resilient to forces. So, once it is utilised as a gasket, it can effectively absorb any movement between two or more mating surfaces. As it absorbs the said movement, any rattles and squeaks are likewise expected to be absorbed as well. Sound can even be dampened due to felt gaskets’ strong resilience.

Another application of felt gaskets is filtration. Felt gaskets have fibres that make them somehow an effective filtration medium for various applications. Once these gaskets are soaked in oil, their filtration becomes more effective, trapping small particles that can be damaging to system components. Felt gaskets soaked in oil are not only effective in filtering elements but can also be useful in sealing moving surfaces like shafts.

Felt gaskets can be maximised in applications that involve feeding low viscosity liquids and lightweight oils. They can also be utilised for oil and grease retention, sound deadening, and anti-rattle applications.
