    What are Nomex Gasket?

    Gaskets, including those made from Nomex, play vital roles in sealing, insulating, and gap-filling applications. Typically, they are intricately shaped pieces positioned between two surfaces to fill gaps or establish barriers.

    Nomex, a synthetic aromatic polyamide polymer, is formulated from two types of synthetic aramid polymers: 'floc,' providing mechanical strength, and 'fibrids,' microscopic fibrous binding particles that contribute to specialized Nomex boards and papers.

    Calendering, a process involving heat and pressure, can enhance the density of these papers and boards, creating a lasting bond within the fiber structures. Nomex finds use in applications demanding high-temperature performance, dielectric strength, and resistance to hazardous chemicals.

    Why use Nomex Gasket?

    Nomex gaskets, crafted from boards or papers, are purpose-built for electrical insulation applications in both high and low-temperature environments. These gaskets impede electric current flow, safeguarding electrical conductors from contact with people or tools during installation, repairs, or device usage.

    Furthermore, electrical insulation gaskets effectively prevent electrical arcing, the phenomenon where electrical current passes through the air between conductors, causing ongoing electrical discharges due to gas breakdown. Nomex gaskets excel in this and various other electrical insulation scenarios.

    They exhibit exceptional qualities, including high-temperature resistance, chemical resilience, superior electrical insulation properties, and flame retardancy.
