Gaskets have been very useful for many industries due to their dependable sealing capabilities. With these products, they can effectively fill the space between two or more objects and prevent leaks even under compression. They likewise close any gaps that could generate damages to the objects.
To date, there are a lot of materials that can be utilised in generating and forming the gaskets. One of the most common materials for gaskets is metal. Metal gaskets have been useful for heavy-duty applications since they can withstand extreme temperatures, chemical exposure, and strong pressure. Other materials that are utilised for gaskets are rubber, cork, and fibre. Both rubber and cork gaskets are known for their flexibility, while fibre gaskets can be effective in low-temperature and high-pressure applications.
But one particular gasket material that is used by more and more industries is polyurethane. Polyurethane boasts a wide variety of features that make it great for gasket production.
Primary Composition of Polyurethane
Polyurethane is comprised of organic units that are combined with urethane links. The main organic units that this material contains are di- and tri-isocyanates and polyols. As more elements are added to the basic composition of polyurethane, it is expected to boast significant improvements over its thickness, density, firmness, colour, and other characteristics.
When processed optimally, polyurethane can be utilised in generating flexible and rigid foams, adhesives, coatings, varnishes, electrical potting compounds, and many more. Flexible and rigid foams are known to be one of the top applications of polyurethane.
Advantages of Polyurethane Gaskets
One of the applications of polyurethane foams is the creation of gaskets. Polyurethane gaskets can be easily utilised by many industries thanks to their diverse properties and characteristics. Their thickness, density, firmness, colour, and others can be modified according to one’s liking, making it possible for industries to perfectly match the qualities of the gaskets to their intended applications.
Aside from their flexibility, polyurethane gaskets have been utilised by many industries thanks to their resistance to corrosive elements, chemicals, greases, oils, fats, hydrocarbons, and ozone. They can likewise absorb impact and isolate vibration, protecting products from easily getting damaged. Polyurethane gaskets can also perform well across a wide temperature range without getting brittle or deformed. They can even withstand fire without depending on additives.
Applications of Polyurethane Gaskets
All the advantages of polyurethane gaskets make them great for sealing screens, automotive parts, and heating, ventilation, and air conditioning systems. They can also be utilised for bulk material transfer systems, liquid transfer systems, hydraulics, hydrostatic testing, and non-destructive testing.
To know more about polyurethane gaskets, you can call us at Gasketech. We are a manufacturer and supplier of gaskets and sealing washers, extrusions, and mouldings for all industries. We can likewise supply and service gaskets for imported and local machinery working in local conditions.
One small yet vital component that is being utilised by a lot of manufacturers today is the gasket. A gasket is a mechanical seal that can effectively fill the gap between two or more mating surfaces. Through the installation of this mechanical seal, it can prevent leaks despite being under compression.
Tons of materials can be utilised in generating a gasket. One of these materials is natural rubber. A natural rubber gasket is popular among manufacturers since it can resist water, withstand shock and vibration, and work effectively with metal surfaces. A gasket made from silicone rubber, alternatively, has an added resistance to weather elements. It likewise has an electrical-insulating property. Cork is another material that is maximised in generating a gasket thanks to its resistance to oil products and solvents.
But one material that is great in many aspects is the compressed non-asbestos fibre or CNAF. This specific material is identified to be the replacement for the dangerous asbestos material.
Primary Qualities of the CNAF Material
As mentioned before, the CNAF material serves as the perfect replacement for asbestos as the latter has been verified and declared as a toxic and dangerous material. Some materials that are utilised in creating CNAF are aramid fibres, fibreglass, and rubber.
What makes CNAF great for gasket production is that it does not boast the same toxic qualities of the beloved asbestos material. And since the CNAF is not toxic, it can effectively be used to generate products that can be useful for everyday applications without causing any dangers to the surroundings. Another great quality of CNAF material is that it can resist damaging elements. Several damaging elements that the material can resist are corrosive elements, chlorides, oil, and acids. The said material can even withstand extremely high temperatures.
Many parts and components can be generated out of CNAF thanks to its flexibility. CNAF materials can be cut to generate parts and components with varying sizes and shapes, making them useful for manufacturers and industries that want to offer quality products.
