Since the invention of felt in the 17th century, its use has gained prevalence across several walks of life. While most of the fabrics that abound today are woven, felt has managed to retain a nonpareil nonwoven identity. Being nonwoven means that its production is embarked with several machines tailored to spinning, knitting, etc. Besides, this material is typically characterized by significant density, making it the perfect fit for several heavy-duty purposes, more pronounced in the aluminum extrusion industry.
Since its invention, felt has taken various forms, one of the oldest and most popular being the industrial felt. Thanks to its countless unique properties, this type of felt have a boundless range of applications – from sound insulation to thermal insulation and several others.
In this article, we will cover all you need to know about industrial felt.
In the last few decades ago, felts were largely handmade. However, industrial production today relies on several high-end equipment and machinery. In a nutshell, the production requires a mixture of different top-quality wool materials. When you press these tools into polyester and nylon fibers, the result is industrial felt, which is quite dense.
It is impossible to manufacture industrial felt by weaving, but by mixing, heating, moisture creation, pushing, filling, and drying the range of materials involved. Our industrial felt embodies several features that adhere to the industry standards of wool content, weight, thickness, and other strict tolerances.
Generally, there are two types of industrial felts. Your choice ultimately depends on the specific features tailored to your intended use and application. Essentially, we have the semi-compressed and compact forms of industrial felts. The shapes can be laminated as well as round. In terms of application, you can as well divide them into the filter and refractory felts.
Industrial felts are characterized by significant energy absorption. This property makes it the perfect fit for use as a sound insulator. Besides, it does well to repel thermal energy, which makes it the best material for thermal insulation.
A flash point of 500°C, coupled with its high resistance to external factors such as oil, water, and other chemicals, makes it suitable for several intents. Furthermore, the material is quite flexible. This means that if one part gets damaged, you can always replace it with something similar without any hassle. If compressed, an industrial felt can easily return to its original position as well.
Industrial felt has gained prevalent use in making parts of industrial machinery and components. Firstly, the aluminum extrusion industry relies heavily on industrial felt. As mentioned earlier, it makes the perfect sound and thermal insulator. But asides from these, industrial felt works effectively in making different shock absorbers, gaskets, and oil absorbers, among others.
Its application is more pronounced in the automotive outfit. For instance, it is the primary component of filters in vehicles, which prevent unwanted particles from entering the engine. Similarly, you’ll find its use in refueling tanks, power plants, sandpaper, felt bowls and the list goes on and on.
