What is a “Felt Gasket”?

Felt Gasket: It refers to a gasket that is constructed using felt, which is a type of material made by pressing and compressing fibers together to form a dense, flexible, and often resilient sheet.    Felt gaskets are commonly used in various industrial and mechanical applications where sealing, insulation, or cushioning is required.

Felt gasket sheet are made from felt, a non-woven material with a high degree of compressibility and conformability. The fibers used in felt can vary, but common materials include wool, synthetic fibers, or a blend of both.

The primary function of a felt gasket is to provide a seal between two surfaces, preventing leakage of fluids or gases. Felt gaskets can also offer insulation or cushioning, depending on the specific application.

Felt gaskets are widely used in various industries, including automotive, aerospace, oil and gas, and manufacturing.

They can be found in engines, pumps, valves, and other mechanical assemblies where sealing is critical.

Features & Benefits of Felt Gasket Include:

Product Features

Wear resistance: The felt gasket performs well and resists wear, maintaining its physical properties even under prolonged use.

Tear resistance: High strength, resistance to tearing, unraveling and fuzz.

Absorbability: Highly absorbent, able to absorb and retain liquids or oils, suitable for a variety of application environments.

Chemical stability: provides good chemical resistance and is not easily eroded by most chemical substances.

Felt gasket made from natural fibers such as wool is a sustainable resource as they can be quickly regenerated.

Some felt gasket products are also certified as environmentally friendly materials, such as LEED® certification, indicating that they have less impact on the environment.

Product Benefits

Felt gasket seal is known for their good sealing properties, durability, and ability to conform to irregular surfaces. They can withstand a wide range of temperatures, pressures, and chemical environments.

What Special Features Can Be Incorporated into Felt Gasket?

The felt gasket can incorporate a variety of special features to meet the needs of different application scenarios. Here are some special characteristics that may be incorporated into the felt gasket

Reinforcing material

Wire or fiber reinforcement: To enhance the mechanical strength and wear resistance of the felt gasket strip, wire (such as stainless steel wire) or high-strength fibers can be added to its manufacturing process. These reinforcement materials significantly improve the tensile strength, tear resistance and pressure resistance of gasket.

Multi-layer structure: Using multi-layer stacking technology, felt with different densities, thicknesses or fiber content are laminated together to form a multi-layer felt gasket with complex mechanical properties and sealing properties.

Coating treatment

Waterproof coating: Apply a waterproof material to the surface of the felt gasket to improve its water resistance and prevent moisture penetration and erosion.

High temperature resistant coating: For felt gasket that needs to work in high temperature environments, a high temperature resistant material can be applied to ensure that it will maintain stable performance and seal at high temperatures.

Corrosion-resistant coatings: For aggressive environments, corrosion-resistant materials can be applied to extend the life of the felt gasket and protect it from chemical attack.

Special Fiber Materials

Fiber felt gasket made of special fiber materials (such as ceramic fiber, glass fiber, etc.) can have higher temperature resistance, corrosion resistance or insulation properties. These special fiber materials can meet the specific needs of specific industries or applications.

Adhesive Back or Self-Adhesive Design

For ease of installation and fixing, the felt gasket can be designed with a back adhesive or self-adhesive layer. This design allows the gasket to be attached directly to the surface that needs to be sealed without the need for additional fixtures or tools.

High Performance Sealing Material

Some sealing felt gasket may be coated or filled with high performance sealing materials such as silicone, fluororubbers, etc., to improve its sealing performance and chemical resistance. These high performance sealing materials can maintain a stable sealing effect under extreme conditions.

Cutting and Forming

Design drawings: Design and draw detailed cutting drawings according to the specific size, shape and thickness requirements of the gasket.

Cutting molding: Use professional equipment (such as die cutting machine, laser cutting machine, mechanical cutting machine, etc.) to cut the felt material into the desired shape and size according to the requirements of the drawing. This step requires precise control of the cutting speed and force to ensure smooth, burri-free edges of the gasket.

Back adhesive

According to the use of the product environment and requirements, choose the appropriate type of back adhesive, such as waterproof, temperature resistance, super bonding, etc. We offer 3M, Crown, Soken, Nitto, Sony, Luxking and other adhesive brands.

What Industries Use Felt Gasket?
