Wool Felt Applications

Design Challenges and Application Opportunities


Wool felt is amazingly durable in many applications. It resists aging and it remains dimensionally stable for decades.

Felt functions normally in temperatures ranging from (-) 60 degrees Fahrenheit to (+)180 degrees Fahrenheit — even up to (+)250 F. if allowed to regain its natural moisture periodically.

It is inert to most hydrocarbons as well as most other chemicals. It even resists acids. However, wool fibers can be damaged by alkaline substances.

It does not ignite easily and usually extinguishes itself unless exposed to constant temperatures above its ignition point.

It holds its strength and resilient properties. Wool felt can be stressed to just under its elastic point repeatedly for years and still snap back to its natural shape. Piano hammers are a good example of this characteristic.


Felt Wheel Densities &
General Applications

Felt wheels are available in soft, hard, and rock hard densities for polishing applications on glass to metal surfaces.


Fuel Filters, Air Filters, Vapor Filters

Wool felt can exclude particles down to 0.7 micron.
It is adaptable to virtually any filter configurations. Plugs, accordion-pleated cartridges, sewn bags, and drum heads are among the most common. However, the versatility of felt lends itself to many unusual and critical filtration situations.


Mounting Pads, Shock Absorbers, Vibration Dampers

Felt absorption mounts can reduce the vibrating energy of machines by as much as 85 percent with proper application. Sensitive instruments can be similarly protected from floor and counter vibrations. In some applications, felts of various densities can be laminated for maximum performance in these applications.

Typical Uses

Electric Motor Mounting pads
Shock Absorbers
Vibration Dampers

Vibration isolation felt is durable and stable in the presence of moisture, lubricants, greases, detergents, salts, and chemicals. It conforms to uneven surfaces to block unwanted foreign material from the load bearing area.

Resilient qualities hold up under heavy static and dynamic loads for years without deterioration. This holds true at low temperatures where some materials become hard and brittle.

Vibration isolating felts are available in various densities and thicknesses for mounting light or heavy loads (1-250 psi).


Sound Absorption

Felt absorbs more sound per thickness than other materials making it the leading choice in applications where space is limited,

Typical Uses

Industrial Sound Dampers
Speaker Enclosure Linings
Noise Hood Liners


Manufacturability of Felt

In can be machined

It can be cut, ground and formed like metal in appropriate densities.

It can be die-cut into intricate, high-precision shapes.

It can be heat formed.

It can be bonded to almost any surface
