Gaskets for Non-Metallic Applications

21 October 2020

Gaskets are mechanical seals that can fill the spaces between two or more surfaces and prevent them from any leakage incidents. These functionalities of the gaskets alone make them beneficial for a lot of commercial and industrial applications.

A lot of equipment and components that utilise gaskets are made from metals. However, several applications maximise non-metallic materials and devices. Gaskets intended for non-metallic applications must be able to resist pressure and prevent chemicals, fuels, and other substances from leaking in or flowing out. They must also resist corrosion, chemicals, and other elements that might damage them throughout their operations.

Fortunately, there are a lot of material options that can be used as gaskets for non-metallic applications. Most of these materials can effectively withstand the elements that have been previously mentioned.


Fibre gaskets are mainly composed of natural cellulose that is infused with different types of materials such as rubber, insulating fibre, synthetic fibre, and vulcanised fibre. Fibre gaskets are suitable for non-metallic applications that have low to medium temperatures and pressures.  

Ethylene Propylene

One type of synthetic elastomer is known as ethylene propylene. This type of gaskets is recommended for applications revolving corrosive and hydraulic fluids. They can likewise work under severe weather conditions. This type of gaskets, however, is not suitable for applications that involve oils and fuels.


Mica gaskets are comprised of phlogopite mica paper that is waterproofed with a silicone binder. This type of gaskets is recognised for its good temperature resistance, making it suitable for high-temperature applications. Mica gaskets can be utilised in gas turbines and heat exchangers.


Another material that is part of the elastomer family is nitrile. Nitrile gaskets boast excellent resistance to petroleum products, hydrocarbons, and solvents. They can also effectively withstand tear and abrasion. Nitrile gaskets can be maximised by aerospace, military & defence, and petrochemical industries.


Neoprene gaskets are made from synthetic rubber that can be effective in applications involving water, oil, and other solvents. This type of gaskets is believed to be durable, flexible, resilient, and resistant to compression. They can likewise withstand combustion and extreme weather conditions. 


Polytetrafluoroethylene is a synthetic fluoropolymer of tetrafluoroethylene that can effectively resist chemicals and extreme temperatures. This type of gaskets is typically used in food processing, pharmaceutical, petrochemical, and electrical applications. 


The material polyurethane is a type of polymer that can give superior load-bearing properties, wear resistance, and rebound capabilities. Gaskets out of this material can easily resist the damaging effects of oxygen, ozone, and grease, which makes them suitable for machine mounts and electrical equipment.


Gaskets that are made from silicone are common today since they can effectively work under high temperatures. They likewise do not react with sunlight and ozone, making them great for outdoor use. Silicone gaskets are typically utilised in food processing and medical applications.

All these mentioned gaskets are great for non-metallic applications. For more information about non-metallic gaskets, just give us a call at Gasketech.
