Gasket sheets are essential components used to create seals between two surfaces in various industrial applications, including piping systems, machinery, and equipment. These sheets come in different materials, each suited to specific operating conditions and requirements. Here are some common types of gasket sheets categorized by material:

1. Non-Asbestos Gasket Sheets:

   • Nitrile (NBR): Nitrile rubber gasket sheets offer good resistance to oils, fuels, and other petroleum-based fluids. They are commonly used in automotive, oil and gas, and general-purpose sealing applications.
   • SBR/NBR Blend: Styrene-Butadiene Rubber (SBR) and Nitrile (NBR) blend gasket sheets provide a balance of resistance to water, mild chemicals, and abrasion. They are often used in water applications and low-pressure sealing environments.
   • EPDM (Ethylene Propylene Diene Monomer): EPDM gasket sheets are resistant to weathering, ozone, and UV radiation, making them suitable for outdoor and high-temperature applications. They are commonly used in roofing, HVAC, and automotive sealing.
   • Neoprene: Neoprene gasket sheets offer excellent resistance to weathering, ozone, and aging, as well as good flexibility and mechanical properties. They are often used in marine, automotive, and HVAC sealing applications.
   • SBR (Styrene-Butadiene Rubber): SBR gasket sheets provide good abrasion resistance and sealing performance in low-pressure applications. They are commonly used in gaskets for pumps, valves, and flanges.
   • Compressed Non-Asbestos Fiber (CNAF): CNAF gasket sheets are made from a combination of aramid fibers, mineral fibers, and synthetic rubber binders. They offer good temperature and chemical resistance and are used in various industrial sealing applications.

2. Graphite Gasket Sheets:

   • Flexible Graphite: Flexible graphite gasket sheets are made from high-purity graphite material and offer excellent thermal conductivity, chemical resistance, and sealing performance at high temperatures. They are commonly used in high-temperature and high-pressure applications, such as steam, hydrocarbons, and acids.

3. PTFE (Polytetrafluoroethylene) Gasket Sheets:

   • Expanded PTFE (ePTFE): Expanded PTFE gasket sheets are highly compressible and offer excellent chemical resistance, non-stick properties, and sealing performance at low and high temperatures. They are commonly used in pharmaceutical, food processing, and chemical processing industries.

4. Metal Gasket Sheets:

   • Soft Iron: Soft iron gasket sheets offer good malleability and conformability, making them suitable for sealing irregular surfaces and low-pressure applications.
   • Stainless Steel: Stainless steel gasket sheets provide excellent corrosion resistance and sealing performance in high-temperature and high-pressure applications. They are commonly used in chemical processing, power generation, and oil and gas industries.

These are just a few examples of gasket sheet materials available in the market. The selection of the appropriate gasket material depends on factors such as temperature, pressure, fluid compatibility, and application requirements.
