    What Are Nitrile Insertion Rubber Sheets?

    Nitrile insertion rubber, also called reinforced NBR sheets, is a synthetic rubber material enhanced with a mesh or fabric reinforcement (the “insertion”) running through its centre. This reinforcement prevents stretching under tension, thereby increasing the material's durability, wear resistance, and mechanical strength.

    Available in shore hardnesses from 40° to 70°, nitrile insertion sheets offer the same chemical and thermal resistance as standard nitrile rubber but with added reinforcement for demanding applications.

    They are commonly used to create:

    • Conveyor belts and transfer chutes

    • Automotive and aerospace gaskets and seals

    • Washers, pads, and insulating strips

    • Oil, fuel, and chemical-resistant components

    Why Use Nitrile Insertion Rubber Sheets?

    Nitrile insertion sheets offer a combination of chemical, mechanical, and thermal resistance:

    • Resistant to oils, fuels, solvents, and some acids/alkalis

    • Excellent tensile strength and anti-abrasion properties

    • Maintains performance under stretching or high-stress conditions

    • Works in automotive and aerospace sealing applications

    • Suitable for air, dust, and water-tight seals

    The insertion layer ensures the material can withstand applications where stretch and wear would typically compromise standard nitrile sheets, such as in conveyor systems, transfer chutes, and belting.

    Benefits of Nitrile Insertion Rubber

    • High chemical resistance against oils, fuels, and solvents

    • Waterproof and abrasion-resistant

    • Excellent mechanical strength and durability

    • Tear and stretch-resistant

    • Ideal for automotive, industrial, and heavy-duty applications

    • Can be cut into complex seals, gaskets, and components

    Different Grades of Insertion Rubber

    Advanced Seals & Gaskets Ltd work with a network of trusted suppliers to offer multiple grades of insertion rubber, including:

    • SBR Insertion Rubber (Styrene-Butadiene Rubber): Commercial-grade, cost-effective, general-purpose rubber with good abrasion resistance. Not suitable for harsh chemicals, ozone, strong acids, or hydrocarbons.

    • Neoprene Insertion Rubber (CR): Excellent for use with grease, oil, acids, ozone, and seawater, widely used in marine and industrial applications.

    • EPDM Insertion Rubber (Ethylene Propylene Diene Monomer): Perfect for outdoor and exposed environments, resistant to UV, ozone, weathering, abrasion, and diluted acids.

    Advantages of Using Nitrile Insertion Rubber Sheets

    Solid nitrile insertion rubber is recognised for its ability to resist swelling under exposure to oils and fuels, maintaining sealing performance over time. This makes it a popular choice for:

    • Automotive belting, gaskets, and oil/fuel seals

    • Conveyor belts and transfer chutes

    • Flange gaskets, isolating strips, and sleeves

    • Applications in mining, quarrying, construction, oil & gas, and defence

    Using nitrile insertion sheets is preferred when smaller quantities of custom parts are required, as it reduces waste and allows for efficient large-surface coverage.
