Vulcanized Fiber (Fishpaper) – Chemically hardened paper with excellent dielectric strength and high friction and oil resistance. It is relatively inexpensive.
Cellulose Fiber – Used in applications requiring medium flange-bolt pressure. This product has some fuel resistance, but is degraded by acids and water. It can handle temperatures of 250°F.
Reinforced Cellulose Fiber – This gasket material is reinforced with a rubber binder, which adds resistance to some chemicals and limits moisture absorption, which can improve the seal. Used in applications requiring medium flange-bolt pressure and a maximum temperature of 350°F.
Reinforced Aramid Fiber – This material contains a rubber binder that helps to limit moisture absorption. It is used in applications requiring medium to heavy flange-bolt pressure. There are a variety of rubber binders available, and this material can handle temperatures up to 750°F. Thicknesses range from 1/64” to 1/16″.
Reinforced Aramid Fiber/Compressed – This compressed material contains a rubber binder to help limit moisture absorption. It is used in applications requiring heavy flange-bolt pressure. There are a variety of rubber binders available, and this material can handle temperatures up to 750°F. Thickness ranges from 1/64″ to 3/16″.
Graphite Sheet – This product is used in very high temperature applications (900°F) and is expensive.
