Knowing the Benefits of PTFE Gaskets

04 December 2020

When it comes to sealing two mating surfaces, most industries would utilise gaskets in fulfilling the said process. Gaskets are designed to fill the gap and space between two objects. And as they are tightly sealed on a specific component or machine, they can effectively prevent any leakage issues even under high pressure and compressive loads. 

The selection of materials for manufacturing gaskets has become wider ever since the technology of creating them becomes available. Some gaskets today can boast non-metallic features and properties, while others can be either metallic or semi-metallic. Materials that can be maximised in creating and producing gaskets normally include stainless steel, aluminium, nickel, silicone, and neoprene.

One material that is now becoming popular in terms of gaskets is polytetrafluoroethylene or PTFE. PTFE gaskets boast numerous features and benefits that make them popular in industrial assemblies right now.

Chemical Resistance

PTFE gaskets have become popular in terms of industrial assemblies and applications due to their excellent chemical resistance. To date, there are only a few chemicals that can directly attack and damage the PTFE material. Fortunately, these chemicals are not present in day-to-day applications, which is why these gaskets can be applied to applications that deal with both standard and aggressive chemicals.

Temperature Resistance

Another advantage of PTFE gaskets over other types of gaskets is that they can resist a wide range of temperatures. PTFE gaskets can easily withstand applications that have temperatures of up to 260 degrees Celsius. And given the range of temperatures that these gaskets can easily work on, they are normally applied on applications that can get truly hot without causing fire or melting.

Low Surface Friction

As mentioned, gaskets are intended to seal two surfaces together. Through PTFE gaskets’ low surface friction, they can easily be installed on these surfaces without obtaining damages. Acquiring low surface friction likewise allow PTFE gaskets to have less wear, tear, heat, and risk of fire. The coefficient of friction of PTFE gaskets is known to be the third lowest among gasket materials.

Guaranteed Longevity

Some gaskets are installed on components that must be used outdoors. Luckily, PTFE gaskets can easily withstand different weather elements. From ultraviolet rays to moisture, PTFE gaskets are guaranteed to last for a long time even under these mentioned elements. Instances of discolouration, embrittlement, and corrosion are likewise not common with PTFE gaskets.

Easy Maintenance

The surface of PTFE gaskets is non-stick, helping them get rid of dirt and other similar elements very quickly. The self-cleaning texture of PTFE gaskets allows them to be maintained easily without the need for any additional tools and solutions. The coating of these gaskets is also non-wetting, which can help them achieve clean surface all the time.
