What Is A Nomex Felt Pad

Nomex felt pad as a special felt with unique and vital features. Manufacturers create these felt pads with an extra protective capacity that makes them heat-resistant, flameproof, and resistant to scratches. They’re the best alternative for graphite slats as their materials resist graphite-prone blackening and wear off. You can use the Nomex felt pads in various appliances at industrial setups.

Nomex Felt Pad Features

Nomex felt pad offer a range of features that make them suitable for various applications requiring heat resistance, flame resistance, and mechanical stability. Here are some key features of Nomex felt pads:

Heat Resistance: Nomex is known for its exceptional heat resistance. It can withstand high temperatures without melting or degrading, making it ideal for applications where exposure to heat or flames is a concern.
Flame Resistance: Nomex is inherently flame-resistant due to its chemical structure. It doesn’t support combustion and will self-extinguish when the flame source is removed, providing an added layer of safety in environments where fire risk is present.
Thermal Insulation: Nomex felt pads provide good thermal insulation properties, helping to protect surfaces, equipment, or materials from heat transfer. This can be particularly useful in applications where heat needs to be controlled or isolated.
Mechanical Strength: Nomex felt pads are mechanically stable and offer good tensile strength and durability. This makes them suitable for applications that require resistance to wear, abrasion, and mechanical stress.
Chemical Resistance: While not impervious to all chemicals, Nomex has some level of resistance to certain chemicals, acids, and solvents. This can make Nomex felt pads suitable for applications in environments where chemical exposure is a concern.
Low Thermal Shrinkage: Nomex has low thermal shrinkage even at elevated temperatures, which helps maintain the integrity and shape of the material in high-temperature environments.
Flexibility: Nomex felt can be manufactured in various thicknesses and densities, allowing for flexibility in designing and using Nomex felt pads for specific applications.
Electrical Insulation: Nomex is also used in electrical applications due to its excellent electrical insulation properties. Nomex felt pads can provide insulation and protection in electrical equipment and systems.
Lightweight: Nomex is relatively lightweight compared to some other heat-resistant materials, which can be advantageous in applications where weight is a consideration.
Ease of Fabrication: Nomex can be easily cut, sewn, and molded into various shapes and forms, allowing for customization and adaptability in different applications.
Longevity: Nomex felt pads tend to have a long service life due to their resistance to heat, flames, and wear. This can result in cost savings over time as replacements are less frequent.

Nomex Felt Pad for aluminum extrusion

Using Nomex felt pads for aluminum extrusion applications is a common practice in the manufacturing industry. Aluminum extrusion involves forcing heated aluminum through a shaped opening or die to create complex cross-sectional profiles. During this process, the extruded aluminum is hot and malleable, which makes it necessary to have proper insulation and handling methods to ensure efficiency and safety. Nomex felt pads offer several advantages when used in aluminum extrusion:

Heat Insulation: Nomex felt pads provide effective thermal insulation, preventing the heat from the extruded aluminum from transferring to other surfaces or equipment. This insulation helps maintain a controlled extrusion process and reduces the risk of heat-related damage.

Surface Protection: The soft and cushioning properties of Nomex felt pads protect the extruded aluminum from scratches, abrasion, and damage as it moves through the extrusion process. This helps maintain the quality and finish of the final extruded profiles.

Heat Resistance: The inherent heat resistance of Nomex ensures that the felt pads can withstand the high temperatures associated with the extrusion process without melting or degrading. This durability contributes to a longer service life for the pads.

Non-Marking: Nomex felt pads have non-marking properties, which means they won’t leave marks, residue, or stains on the extruded aluminum surfaces. This is important for maintaining the appearance and quality of the extruded profiles.

Uniform Pressure Distribution: Nomex felt pads can be designed and positioned to provide uniform pressure distribution across the extruded aluminum as it passes through the die. This helps ensure consistent extrusion results and reduces the risk of defects.

Reduced Die Wear: The cushioning effect of Nomex felt pads can help reduce wear and tear on the extrusion dies, prolonging their lifespan and reducing maintenance needs.

Flexibility: Nomex felt pads can be easily shaped, cut, and customized to fit specific extrusion profiles and equipment. This flexibility makes them adaptable to various extrusion setups.

Safety: The flame-resistant properties of Nomex enhance safety by reducing the risk of fire or combustion in the event of contact with high-temperature aluminum or hot equipment.

Easy Handling: Nomex felt pads can be easily handled, replaced, and cleaned, contributing to a streamlined extrusion process.
