Proper Material Choices Essential to Application Success<\/h2>\n

There are countless material compounds available for use in sealing applications. But when you need near-universal chemical and thermal performance, perfluoroelastomer seals have proven to be in a class of their own.<\/p>\n

Perfluoroelastomer compounds, also known as FFKM<\/a> for short, are elastomeric forms of polytetrafluoroethylene (PTFE)<\/b> \u2014 itself a versatile and popular material. Due to a fluorinated backbone (and higher fluorine content over fluoroelastomer or FKM<\/a> compounds), perfluoroelastomers<\/b> gain additional elasticity, which helps earn usage in a number of demanding applications.<\/p>\n

The world has taken note. With a projected compound annual growth rate of 2.4%<\/a>, the world market for FFKM is expected to grow from $377.3 million to $446.3 million in the next five years. The material\u2019s unique characteristics make it a favorite in chemical processing industry (CPI) applications, particularly in North America, and it\u2019s this market that is expected to be a major driver in that projected growth.<\/p>\n

Why Choose Perfluoroelastomer Seals?<\/h2>\n

Let\u2019s take a look at why this premium material is experiencing a growing demand. FFKM compounds<\/a> are valued for their ability to handle the harshest conditions and most demanding environments. If you need strong chemical compatibility<\/a> attributes, thermal resistance in high (or low) temperature environments \u2014 or both \u2014 perfluoroelastomers provide the best coverage available. Combined with versatility and durability, these have made FFKM compounds a go-to choice across many industries.<\/p>\n

Here\u2019s a breakdown of those aforementioned strengths.<\/p>\n

Chemical Resistance<\/h3>\n

Perfluoroelastomers are the most chemically resistant elastomers available and \u2014 depending on the specific formulation \u2014 can provide strong resistance to a specific element or a broad array of potential chemicals. For example, FFKM can resist more than 1,800 different chemicals, including hydrocarbons, oils, and fuels. Additionally, a perfluoroelastomer o-ring will have high resistance to steam, various solvents, ozone, and weathering.<\/p>\n

Because of all this, FFKM has become the desired material for many CPI applications and has been tested and proven to be the best choice<\/a> when engineering sealing solutions for applications dealing with steam environments.<\/p>\n

Thermal Stability<\/h3>\n

No other compound can offer the protection for extended periods and at the highest temperatures<\/a> that FFKM provides. While the ranges vary depending on the specific formulation used, perfluoroelastomer compounds can be used to provide thermal resistance to temperatures ranging from 335 degrees Celsius (635 Fahrenheit) at the upper end of the spectrum, to -46 C (-51 F) on the colder end.<\/p>\n

Seals operating in lower temperatures will suffer a loss in flexibility; those working in high temperatures will see material alterations, potentially leading to issues like gas absorption and rapid decompression<\/a>. But by using FFKM compounds, designed and formulated for those extreme conditions, you can ensure greater stability, performance, and dependability as the materials will better adhere to their original properties.<\/p>\n

Versatility and Reliability<\/h3>\n

PTFE itself, one of the building blocks of FFKM compounds, lends beneficial attributes as well. PTFE is known for its high flexural strength, even in low temperatures, and provides a low coefficient of friction. This means perfluoroelastomer compounds will also have excellent mechanical wear-and-tear resistance or resilience. Combined with the chemical resistance and thermal stability characteristics, FFKM compounds will give the most durability and performance in the most demanding applications. This will help avoid failures and downtime, which save money in operating costs and alleviate dangerous risks to workers, equipment, and the environment.<\/p>\n

All of these characteristics have helped make FFKM the preferred choice for essential seals in a host of industries, including (but not limited to):<\/p>\n
