Numerous materials can be used in manufacturing and producing gaskets. Some of these materials are silicone, natural rubber, cork, and compressed non-asbestos. Each of these materials has its own set of properties that make them beneficial for specific industries. 

But many industries opt for polyurethane gaskets due to the features they have.

The base material, polyurethane, is generated by reacting a polyol with a polymeric isocyanate or a diisocyanate. These elements make polyurethane very useful for a wide array of industries. Here are some reasons why many industries opt for polyurethane gaskets for their applications.

Endures Temperature Fluctuations

One of the reasons polyurethane gaskets are preferred by industries over others is they can endure temperature fluctuations. By using polyurethane as the base material, these gaskets can easily attain flexible elements that allow them to withstand temperatures between -73 degrees Celsius and 120 degrees Celsius. Their resistance to these temperatures allows them to be very useful for applications exposed to hot and cold environments or processes.

Resists Environmental Elements

Another reason why polyurethane gaskets are picked over others is they can resist elements from the surroundings. Some gaskets need to be placed outdoors. Since these areas are often exposed to sunlight, water, and other harsh weather elements, the gaskets should be able to withstand them. Polyurethane, fortunately, does not get damaged when exposed to these elements, making it the perfect material for producing various types of gaskets.

Withstands Abrasion and Friction

Gaskets are often exposed to abrasion and friction. Without using the right material, they might get damaged in a short time. Polyurethane gaskets, fortunately, have excellent abrasion resistance, allowing them to resist wear generated by friction. Using polyurethane gaskets can help industries carry out their operations without expecting sudden downtimes and emergency repairs.

Allows High Load Bearing Capacity

Aside from their resistance to elements and abrasion, polyurethane gaskets are also picked by industries as they can cater to high load-bearing capacity. Gaskets are installed in areas where a high load is expected. Without using the right type of gaskets, they may end up cracking and obtaining other similar damages, affecting the overall operations of industries. Polyurethane gaskets, fortunately, have a high load-bearing capacity making them effective under intense pressure and heavy vibration.

Permits Additional Customisation

One more reason industries prefer polyurethane gaskets over others is they permit additional enhancements and customisation to their overall specifications. Not all industries have similar needs. Fortunately, polyurethane gaskets can be customised with different thicknesses, sizes, colours, and other details. They can even be altered to meet the application requirements of specific industries.

Clean and potable water is essential to anyone’s life. Without ensuring its cleanliness, it will only make people sick and affected by a wide array of diseases and illnesses.

To ensure that people can attain clean and potable water, it must be treated through water treatment facilities. Water treatment facilities are equipped with parts and devices that can make water safe to drink and pleasant to taste. They can also make sure that the supply of water will meet the standards of a community. They even ensure that the water supply would be able to reach all properties.

Now, for water treatment facilities to work appropriately, they must be equipped with the right gasket materials. Installing the right ones for water treatment facilities can ensure that they can operate safely, protect the environment, prolong their service life, and minimise maintenance and inventory costs.

The Problem with Styrene Butadiene Rubber

Styrene-butadiene rubber (SBR) is one of the most used materials for gaskets. What is great about this material is it offers excellent crack endurance and abrasion resistance. It can also provide a good compression set and water resistance. These qualities make it useful for gaskets intended for potable water applications. 

However, SBR gaskets are not recommended for water treatment facilities since they can degrade naturally over time. Given the operating conditions of these facilities, they will only meet the end of their service life very quickly. SBR gaskets are also not ideal for water treatment facilities due to their low compressive strength. Even water treatment chemicals like chloramine, sodium hypochlorite, and others may easily compromise the qualities of these gaskets, making them not the best option for these facilities.

Compressed Non-Asbestos for General Use

Water treatment facilities that process non-potable water, steam, and other waste products may take advantage of gaskets out of compressed non-asbestos (CNA). CNA gaskets are recommended for these facilities since they have excellent sealing characteristics, superior ease of cutting, and relatively low initial and operational costs. 

CNA gaskets are comprised of fibre, binder, and filler. They also utilise a small percentage of solvent-based vulcanising chemicals that can cure the rubber-based binders during their manufacturing processes. The fibre element of CNA gaskets helps in fortifying their tensile and compression properties, while the binder element ensures that the gaskets will become more flexible. Fillers, ultimately, are integrated into the CNA gaskets so they can effectively control creep and minimise cold flow.

Taking Advantage of Polytetrafluoroethylene

As for critical service and chemical use, filled polytetrafluoroethylene (PTFE) gaskets are the ones needed. What makes these gaskets useful for these applications is they have excellent chemical resistance, high sealability, and long service life.

Despite being exposed to various environmental conditions, filled PTFE gaskets will not break down easily compared to others. They are also inert to almost all types of chemicals, which makes them the best option for chemical applications. Another great thing about filled PTFE gaskets is they can withstand loads of up to 15,000 psi, which is ten times more than the compressive strength of SBR gaskets.

Different industries utilise a wide array of mechanical components to ensure that their tools, structures, and others can work optimally. One of the components they use is the gasket.

A gasket is a mechanical sealing component that can fill the space between two or more objects. Normally, it is utilised by industries to achieve excellent sealing to tools, structures, and others. Once installed, the gasket can effectively prevent chemicals, oils, water, dust, and other contaminants from going in and out of the mating surfaces. Aside from sealing, a gasket can also be useful for dampening vibration, shock, and other damaging forces to devices, tools, and machines.

Properties of a Reliable Gasket

The functions associated with the gasket can be crucial to industries that use them. And so, if you are one of the businesses that must utilise this mechanical sealing component, you must ensure that it boasts the correct properties. Failure to pick the right gasket will only lead to hazardous leaks. It can also cause damage to the objects that require proper sealing.

A gasket can be effective in performing its functions if it can withstand the temperature of the fluid and other elements that it intends to handle. It must also be able to resist the pressure range of the same fluid. And once it comes in contact with the fluid and other elements in the surroundings, the gasket should not corrode and generate impurities.

A reliable gasket should likewise withstand any movement that may occur due to temperature and pressure changes. Ultimately, a reliable gasket should always be available and must not cost too much.

Selecting the Right Gasket

When selecting the right gasket for your application, you must ensure that its material will be compatible with the fluid present on your tools and other objects. It must also have the ability to resist the temperature and pressure of the system. Lastly, it must last for a long time.

Crucial elements may be checked to ensure that your gasket can be compatible with the involved fluid and last for a long time. These elements include the following.

Industrial machines and tools should be assembled properly to ensure that they remain functional throughout their service life. Proper assembly of these things, after all, can prevent leakage.

Leakage can be a huge issue among industrial machines and tools since they are generally made from material-sensitive components. Once moisture, air, and other elements infiltrate their internal components, they may easily get damaged. Materials that come out of the machines and tools canlikewise cause damage to nearby components.

One way to prevent leakage from happening is by installing gaskets. Gaskets are mechanical seals that can fill the space between two or more objects. Tons of materials can be used in making them. Many industries, however, often opt for either natural or synthetic rubber.

Natural Rubber Gasket

Natural rubber, as its name implies, is typically extracted from nature. Produced primarily by tapping trees, natural rubber can be mostly found in tropical climates.

What is great about natural rubber gaskets is they have high tensile strength. They likewise have high tear resistance, fatigue resistance, and low odour. The fatigue resistance of these gaskets prevents them from getting damaged due to chipping, cutting, or tearing. Another great thing about natural rubber gaskets is they can adhere to other materials optimally. 

As for their downsides, natural rubber gaskets cannot completely resist the effects of heat, light, and ozone exposure. They likewise have natural proteins that can trigger allergic reactions in some people, especially if they are exposed to these things for a long time. 

Synthetic Rubber Gasket

Synthetic rubber, on the other hand, is produced from polymers. These materials can imitate the qualities of natural rubber. They may even sometimes provide more enhancements to synthetic rubber.

Synthetic rubber gaskets have been preferred by many industries as they can provide better abrasion resistance. They can also withstand chemicals, fluids, electrical heat, and ozone. Synthetic rubber gaskets can even withstand the effects of aging and fire, resist grease and oil, and remain flexible at low temperatures. These qualities make them very useful in extreme temperature and corrosive applications. 

Although synthetic rubber gaskets already boast properties that natural rubber lacks, they still have some drawbacks that industries often consider. Synthetic rubber gaskets have poor tensile strength and tear strength. They also have poor mechanical properties.

Picking the Best Rubber

When picking the best rubber material for your gaskets, you must primarily consider their intended use. You must also know the condition of the environment where the gaskets will be installed or placed. Budget can also be a factor in picking the material for your gaskets. 

If you need help in picking the best rubber gaskets for your application, you can contact us at Gasketech. We have a dependable expert who is ready to discuss sealing and leakage problems with you. We can also readily service and supply quality gaskets that you may need for your local machinery.

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.
