What are Elastometric Gaskets?29 May 2016
Over the years, tough operating environments have challenged our engineers by introducing more pressure variables and higher temperatures. Mechanical assemblies use strong alloys and smart designs to deal with these stresses, but there’s still the surface-to-surface junctions between each component to handle. Substance-fatiguing fuels and corrosive oils aren’t about to go away, after all, not when they power every industrial domain. We need a better solution, the incorporation of elastometric gaskets, and a highly compressible polymer that retains its seal even when these harsh forces are at their peak.
Gaskets provide a powerful seal between two surfaces, but they will fail if their design isn’t up to the job at hand. Manufactured to function with assurance when operating conditions are at their toughest, elastometric gaskets fill their feature set with aptitudes that other sealing materials sadly lack. The shaped seals compress superbly when flange fasteners are fully tightened, but this compressibility factor does not undermine the elasticity of the material, meaning it will spring back into shape when the two surfaced are opened for maintenance. Additionally, the viscosity of the polymer ensures the rubber-like substance conforms to every irregular outline of the two mating parts, which enhances the seal and eliminates any possibility of leakage.
Fluid Managing Attributes
The above passage relates to the mechanical talents of this gasket medium. It compresses and decompresses, remains flexible as high pressures are applied. Next, gaskets made from this multi-talented chemical compound also sport a number of essential environmental gifts. The molecular structure of the tough elastomer is indeed flexible and rubber-like, but its chemical bonds are fixed in other ways. The gaskets won’t crack or become brittle when temperature spikes are part of the application sphere. This means high temperatures won’t melt the substance and low temperatures won’t cause the tough material to stiffen and develop fractures. Similarly, elastometric gaskets don’t fail when caustic chemicals or fuels are in the pipeline. They’re also a logical choice for the geometrically detailed seals used in engine housings and mechanism fuel lines, as the polymer is a reliable performer when any of these aggressive liquids are part of the lifeblood of a working mechanical system.
Gaskets with elastomeric materials are viscous and elastic, soft and flexible, but they exhibit strong mechanical and chemical resistance features. Viton is a prime example of this high-performing substance, as are the fluoro-silicone and fluoroelastomer families that create a secure seal when vibration, oil, or challenging thermal events are part of the mechanism in question.
