Fell (rubber sheet)

Fells come in various forms and materials, depending on the application and requirements. They are generally used for sealing, for protection against wear or for reinforcing components.

Typical applications of fells

Area	Application	Benefit
Sealing technology	Elastic layers for sealing	Protection against leaks and wear
Materials processing	Fell-like coatings on surfaces	Improved feel and durability
Textile industry	Technical textiles with fell-like structures	Thermal insulation, flexibility
Automotive engineering	Protective layers in interiors or mechanical components	Durability, protection against abrasion

Fells can be made from different materials, depending on the specific requirements. The following table gives an overview of the common types:

Type	Material	Properties	Typical applications
Elastic fells	Rubber, silicone	Flexible, durable, waterproof	Seals, protective layers
Textile fells	Technical textiles	Thermally insulating, breathable	Clothing, insulation
Plastic fells	Polyurethane, PVC	Robust, chemical-resistant	Protective covers, coatings

• Protection against wear: fells protect components against abrasion and external influences.

• Flexibility: elastic fells adapt to irregular shapes.

• Durability: fells increase the service life of the protected components.

• Multifunctionality: in addition to protection, many fells offer additional functions such as insulation or sealing.

• Material selection: not every material is suitable for every application.

• Costs: high-quality materials can be expensive.

• Maintenance: some fells require regular care to maintain their function.

Fells and coatings perform similar tasks but differ in their structure and application:

Feature	Fells	Coatings
Structure	Flexible, often multi-layered	Solid, thin
Material	Elastic, textile-based	Plastic, metal
Task	Protection, sealing, reinforcement	Surface protection
Typical applications	Seals, protective layers	Corrosion protection, appearance

• What are technical fells? Technical fells are flexible, protective layers used in industrial applications, e.g. for sealing or coating.

• Which materials are fells made from? Fells can be made from rubber, silicone, textiles or plastics such as polyurethane.

• What advantages do fells offer over other protective systems? Fells are flexible, durable and often multifunctional, as they can provide protection, sealing and insulation at the same time.

• Are there special care requirements for fells? Depending on the material, fells must be cleaned or maintained regularly to ensure their protective function.

Fells are flexible, multifunctional layers that are indispensable in numerous technical and industrial applications. They provide protection, sealing and insulation and contribute to the durability and efficiency of components. Whether in sealing technology, automotive engineering or textile processing, fells are an effective solution to many challenges.
