Introduction
Industrial felt is one of the most versatile engineered materials used across modern manufacturing.
From vibration damping in automotive components to acoustic insulation in buildings and protective padding in packaging, industrial felt offers a unique combination of durability, cushioning, insulation and adaptability.
Available in a wide range of material options, densities and thicknesses, felt can be converted into highly specialised components through processes such as slitting, die-cutting, kiss-cutting, laminating and adhesive coating. These capabilities make felt suitable for countless industrial applications where performance consistency and reliability are essential.
This guide explains everything you need to know about industrial felt, including material types, key properties, common applications and the converting services used to create finished felt components.
What is Industrial Felt
Industrial Felt is a non-woven textile manufactured by compressing fibres together under carefully controlled conditions of heat, moisture, pressure, and mechanical action.
Unlike woven fabrics, felt does not rely on an interlaced structure. Instead fibres are bonded mechanically, thermally or chemically to create a material with consistent thickness and performance characteristics.
Industrial felt is manufactured from a variety of fibre types including:
- Wool
- Polyester
- Polypropylene
- Acrylic
- Aramid fibres
- Recycled fibres
- Blended materials
The selection of material depends on the intended application and required properties such as temperature resistance, durability, cushioning or acoustic performance, along with flame resistance, rot and moth control, and chemical resistance.
The characteristics of felt can be engineered to provide:
- Compression resistance
- Shock absorption
- Lubrication retention
- Thermal insulation
- Acoustic absorption
- Surface Protection
- Filtration of liquids and gases
- Sealing properties
Industrial felt is typically supplied in sheet, strip, roll, washer, pad, disc, gasket, and die-cut component formats available as individual components or kiss-cut on rolls and sheets.
Types of Industrial Felt
Wool Felt
Wool felt remains one of the most widely used industrial felt materials due to its excellent balance of mechanical and physical properties
Key benefits include:
- High resilience
- Excellent compression recovery
- Good wear resistance
- Natural lubrication retention
- Thermal insulation properties
- Excellent sealing characteristics
Wool felt is commonly used for:
- Bearing lubrication pads and strips
- Wipers
- Oil retention systems
- Gaskets
- Seals
- Anti-vibration components
- Packaging
- Acoustic products
- HVAC systems
Because wool fibres naturally contain microscopic scales on their surface, the felting process of moisture and mechanical action raises the scales and lets them interlock with each other. The more they are processed, the more they interlock and the tighter and harder the resulting product becomes.
This helps determine the final characteristics of the product from one being extremely soft and plush to the other extreme of being very hard and non-compressible.
Needle Felt
Needle felt is produced through a mechanical process that entangles fibres using specialised needles.
Predominantly employed in the manufacture of polyester and man made fibre felts, needle felts can offer some specific advantages in certain sectors.
- Large weight range
- High volume production capacity
- Consistent density across the roll
- excellent sound absorption
- Can be further profiled for specific air flow characteristics
- Used widely in filtration
- Can be made from recycled fibres
- Excellent End of Life properties
Typical applications:
- Filtration of liquids and air
- Anti-scratch pads
- Silence tapes in automotive
- Vibration control systems
- Acoustic panels
- Furniture protection
- Packaging
- Craft
- Commercially advantageous to wool felt in certain applications
Blended Felts
Many applications utilise blends of wool and synthetic fibres to achieve a balance of performance and cost.
The majority of industrial felts are blends of wool and viscose in a variety of quantities.
British Standards BS4060:2006 only recognises felt with a minimum of 75% wool content and up to 100%.
Any wool felts that are manufactured to contain less than 75% wool do not meet the criteria of the British Standard.
Blending wool with viscose is not deemed to be detrimental to the general characteristics of the felt but is considered a commercial decision to keep the costs as attractive as possible for the consumer.
It should be noted that the inclusion of non-wool fibres will alter the absorption abilities of the felt by a small margin as wool fibres are hollow, whereas synthetic fibres are solid.
Certain products can be tailored to suit specific requirements:
- Compression needs
- Wear characteristics
- Cost targets
- Environmental conditions
Adhesive-Backed Felt
Adhesive-backed felt combines a felt substrate with a pressure sensitive adhesive, normally in the form of a tape.
Lamination of felt can be achieved in a number of ways from dedicated lamination equipment for volume rolls or in-line on machines dedicated to laminate and cut in multiple operations.
Key benefits include:
- Quick installation of parts
- Reduced assembly time
- Clean cut appearance to parts
- Consistent positioning
- Suitable for automated production
Applications include:
- Anti-scratch pads
- Vibration reducing components
- Acoustic panels
- Furniture protection
- Industrial assemblies
- Automotive silence tapes
Key Properties of Industrial Felt
The popularity of industrial felt stems from its ability to provide multiple performance benefits within a single material.
Vibration Damping
Felt effectively absorbs and dissipates vibration energy, helping reduce component wear and noise generation.
Industries using felt for vibration control include
- Automotive
- Rail
- Aerospace
- Manufactruing
- Machinery production
Acoustic Performance
The fibrous structure of felt helps absorb airborne sound waves and reduce noise transmission
Industrial applications include:
- Machine enclosures
- Office environments
- HVAC systems
- Vehicle interiors
- Building products
- Flooring systems
Thermal Insulation
Many felt materials provide effective thermal insulation by trapping air within their structure.
Benefits include:
- Heat retention
- Energy efficiency
- Protection from temperature fluctuations
- Improved system performance
Abrasion Resistance
Certain grades of industrial felt offer excellent wear resistance and protective qualities.
Examples include:
- Surface protection
- Packaging inserts

Felt provides a soft but durable barrier between surfaces, protecting sensitive parts during manufacture, transportation and use.
Examples include:
- Glass Transport
- Silage trays
- Packaging
- Internal lining
- Bump stops
- Conveyor guides
