Silicone rubber gaskets are cut from a synthetic elastomer that provides excellent non-stick and electrical insulating properties. It maintains its flexibility and compression set at both low and high temperatures making it a popular option for gasket and sealing applications.
Nitrile rubber gaskets are cut from a synthetic material that provides excellent resistance to most petroleum based fluids, greases and oils. They offer good resistance to abrasion, moderate tensile strength and adequate mechanical properties. Nitrile gaskets are primarily used in sealing applications in the automotive, aeronautical, petrochemical and oil industries. Although nitrile is suitable for use with petrochemicals, it provides poor resistance to ozone and weathering and is not suitable for use with ketones.
Neoprene rubber gaskets are cut from a strong, synthetic material and are primarily used in external sealing applications. The elastomer offers good resistance to abrasion and provides excellent resistance to ozone, ageing and weathering. Neoprene gaskets can be used with animal fats, vegetable oils and inorganic salts, but are not suitable for applications involving aromatic hydrocarbons and ketones.
Insertion rubber gaskets are cut from a material manufactured from a blend of natural and styrene butadiene rubber with a single ply fabric reinforcement. The cotton insertion helps to provide added strength and prevents against over extension. Insertion rubber gaskets are commonly used in general purpose sealing applications and are suitable for use with water and mild chemicals, but should not come into contact with fuels, oils and greases.
FKM rubber gaskets are cut from a synthetic fluoroelastomer and are primarily used in the automotive, aerospace and petrochemical sectors due to their performance in demanding sealing applications. This gasket material offers excellent thermal stability and is highly resistant to hydrocarbons, chemicals, petroleum and oils. They also provide outstanding resistance to weathering, oxidation and ozone, but should not be used with organic acids or ketones such as acetone.
EPDM rubber gaskets are manufactured from a synthetic elastomer and are commonly used in external applications due to the materials outstanding resistance to ageing, ozone and weathering. The gasket has an impermeable surface, provides good resistance to abrasion and is suitable for use with most alkalines, ketones and diluted acids.
