Gaskets are mechanical devices that can keep parts shut off from damaging elements. Many materials can be maximised in producing gaskets. But one of the most popular materials for gaskets that many industries and even households use is rubber. 

Industries and households use gaskets out of rubber since the material can be effective against liquids and gases. Rubber gaskets are likewise popular since they can deform based on the surfaces of the parts. These gaskets, however, still have some weaknesses that they must take care of. Rubber gaskets can be weak against extreme temperatures and light. They also have a shorter service life compared to other gasket materials.

Rubber gaskets may truly be effective in sealing your parts and components. But if you are looking for a reliable alternative for these gaskets, you may want to opt for cork gaskets. Here are some of the most notable properties of cork gaskets that you should know.

1. Resistance to Elements

One of the most notable properties of cork gaskets is their resistance to elements. Just like rubber, cork gaskets can also be effective in most sealing applications as they can withstand the effects of water, ozone, oils, and other gases and liquids. Despite utilising them for a long time, cork gaskets will not age poorly due to their moisture resistance. What makes cork gaskets resistant to these things is that they utilise cell walls out of a reliable waxy substance. 

2. Dependable Elasticity

Another great property of cork gaskets is they have dependable elasticity. Some gaskets may conform to the shape of the parts and components. They may, however, swell on one side whenever they are compressed for a long time. Cork gaskets, alternatively, have a closed-cell structure that grants them quality flexural strength and resilience. Some layers of these gaskets may even be compressed to half of their thickness and still have the capability to regain their original appearance after removing the load.

3. Minimal Conductivity

Cork is often made from suberin, lignin, polysaccharides, ceroids, and tannins. All these elements provide cork gaskets with low conductivity to noise, making them effective in applications that can be sensitive to sound. They likewise have low conductivity to vibration, making them great for anti-vibration applications. These elements even help cork gaskets to become fire-retardant, making them highly effective in thermal insulation, aerospace, and automotive applications. 

4. Ensured Sustainability

One more property of cork gaskets that makes them beneficial for industries and households is they are sustainable. Cork is normally obtained from the harvested bark of the cork oak tree. Since it comes from a natural resource, this material is expected to be free from toxic substances. It is even non-allergenic, making the material perfect for those that have delicate body systems. And once materials out of cork reached the end of their service life, they can easily be collected and recycled.

Different industries use a wide range of mechanical components to ensure that their tools and devices work perfectly. One of the components they use is a gasket.

Gaskets are mechanical components that can fill the space between two or more surfaces of a part or product. The primary purpose of these mechanical sealing products is to prevent leakage from or into the unified surfaces. Additionally, gaskets can stop intense vibration from affecting the functions of the involved part or product.

The Average Life of Gaskets

The average life of gaskets depends on various factors. These factors include their storage temperature, material, and surrounding conditions. 

Gaskets can only last for a long time if they are stored in a location that has around 4 to 27 degrees Celsius. Moreover, their storage area must not be exposed to direct sunlight, chemical vapour, and excessive humidity. These elements, after all, can deteriorate the materials used for creating the gaskets.

And speaking of the materials, gaskets’ average life can likewise depend on their overall materials. Gaskets out of silicone and Viton have a proposed shelf life of 20 years, while those made from non-asbestos fibre, neoprene, EPDM, butyl, and nitrile can last between 5 and 10 years. Natural rubber and natural fibre gaskets, ultimately, have a recommended shelf life of up to 5 years.

As for their operations, gaskets’ service life can be negatively affected if they are exposed to ozone, light, heat, oxygen, humidity, oils, water, solvents, acids, and vapours.

Using Gaskets Repeatedly

The service life of gaskets that have already been used for specific applications is expected to decrease over time. Hence, reputable gasket suppliers would normally suggest that the gaskets not be utilised again once they have been used, even just for a short time.

Gasket suppliers, however, can permit the reuse of gaskets if they have not been exposed to heat. Gaskets that have not been exposed to any fluid can likewise be used again for other applications. Ultimately, industries can reuse their gaskets if their overall thickness and compressibility are still intact.

Gaskets that do not meet the mentioned qualities above cannot be reused since they will not be able to fill the space of the surfaces and save them from leakage issues. Gaskets that have been exposed to elevated temperatures, after all, can already deteriorate their material composition. And when heated, the gaskets may already stiffen up and get brittle. Gaskets that have been saturated with fluid, on the other hand, will only get swollen once they will be reused.

Purchase Quality Gaskets

Even though some gaskets can still be reused, the consensus among gasket suppliers is to never reuse a gasket. After all, the quality of used gaskets has already been affected by many factors. Using a new set of gaskets is much more recommended since they guarantee better sealing and minimal downtimes.

Components of engines, assemblies, and other products must be installed properly and tightly so they remain functional for the rest of their service life. One way to ensure the proper assembly of the components is through maximising mechanical seals.

Mechanical seals like gaskets can fill the space between two or more surfaces, preventing any leak from developing. Most of the time, sealing with gaskets are preferred by many industries since permanent sealing processes like gluing and welding may fail to provide a leak-tight sealing. Mechanical sealing is also maximised in most industrial applications since it can meet most of their assembly requirements.

To date, mechanical seals can be made from a wide variety of materials. But one material that is often used for mechanical seals is Viton.

Primary Composition of Viton

Viton is a mixture of synthetic rubber and fluoropolymer elastomers that comes from DuPont, a reputable producer of chemicals and science-based products. This material has been used in creating rubber seals, gaskets, and O-rings. To date, Viton has four families of polymers.

  1. A (Dipolymers of VF2/HFP) – This type of Viton polymer is comprised of 66% fluorine, making it effective for general-purpose sealing of automotive and aerospace products.
  2. B (Terpolymers of VF2/HFP/TFE) – Maximises 66% fluorine content, this type of Viton polymer is significantly useful for chemical process plants, power utility seals, and gaskets.
  3. F (Terpolymers of VF2/HFP/TFE) – F family of Viton is comprised of 70% fluorine. It can be effective in oxygenated automotive fuels and concentrated aqueous inorganic acids.
  4. Specialty Types – Specialty types such as GLT, GBLT, GFLT, and Viton Extreme can all be useful for the automotive and oil exploration industries.

Viton’s Remarkable Benefits

Since Viton comes from a reputable producer, it can easily provide benefits to industries that use sealing products out of this material.

One of the benefits of Viton sealing products is they can withstand extreme temperatures. From significantly hot temperatures down to extremely low temperatures, Viton sealing products can effectively resist these conditions and continue to seal various assemblies. Another benefit of Viton sealing products is they can resist oil and chemicals. Despite being exposed to these elements, Viton seals, gaskets, and O-rings can operate continuously and avoid unnecessary leaks.

Other elements that Viton sealing products can withstand include atmospheric oxidation, ultraviolet rays, climatic conditions, mould, and fungus.

Some more benefits of Viton are low burning characteristics and reputable electrical properties.

Maximising Viton Products

Viton’s remarkable benefits have paved the way for its usage across industries. Some industries that use Viton are aerospace, automotive, manufacturing, and transportation industries.

Tons of sealing products are now available in the market, ensuring that every application can be conducted successfully. One of the sealing products that industries use today is the gasket.

A gasket is a sealing product that can fill the space between two or more surfaces, ensuring that any leaks will be prevented on their connection points even when under compression. Without the installation of a gasket, the mating surfaces will easily allow external materials to enter and infiltrate them, which can damage them along the way. The lack of this sealing product can likewise lead to energy wastes, high expenses, and failure of the tools or components.

Many industries use gaskets due to their effective sealing capabilities. However, their applications differ from each other, which is why manufacturers have come up with various types of gaskets. Here are some of the industries that use gaskets and the best gasket types for their applications.

Food Processing

Temperature is a key factor when it comes to processing food products. And since a lot of food products are processed in various temperatures, the gaskets used for the tools and other equipment pieces should be able to sustain their qualities. One gasket type that can be effective in the food processing industry is silicone since it can remain stable despite being exposed to high temperatures. Gaskets out of graphite and non-asbestos can also be used in high-pressure environments. 

Automotive

The number of cars that are being manufactured nowadays has been increasing exponentially thanks to the automation of manufacturing processes. However, to ensure that these vehicles can be effective and safe, they must maximise gaskets that can resist high temperatures, fuel, and oil. Gaskets with these qualities are often made from silicone, nitrile, and Viton. EPDM gaskets, on the other hand, are used in creating door seals and plastic foams for car seats. Graphite and non-asbestos gaskets, ultimately, are installed within the combustion areas of the engines as they can withstand high temperatures.

Oil and Gas

The oil and gas industry is another industry that maximises high temperatures in its applications. With the right gasket materials, the industry can easily process oil, gas, and other elements necessary to provide power. Gaskets made from graphite, for instance, can be effective in the oil and gas industry as they can work effectively in high temperature, high-pressure environments. The industry can likewise utilise gaskets made from non-asbestos materials.

Pharmaceutical

The processes involved in the pharmaceutical industry can be delicate at times. And to prevent any accidents from happening, the industry should opt for materials that can handle chemicals and their respective reactions. They must also go for materials that do not allow bacteria to grow significantly. Fortunately, PTFE gaskets are effective in handling chemicals and preventing bacteria from growing. Silicone gaskets can also be maximised in this industry thanks to their durable composition.

Some more industries that use gaskets are aerospace, electrical, petrochemical, and transportation industries. To obtain quality gaskets for your applications, you can call us at Gasketech.
