Why Perfluoroelastomers Are Top-of-the-Line<\/h2>\n

If you\u2019re a purchasing agent or engineer at your organization, you know that there are countless material compounds available in the market. From low-cost Buna-N nitrile rubber<\/a> and mid-range EPDM<\/a> to high-performance HNBR<\/a> and aerospace\/military specification fluorosilicone<\/a>, the sheer number of options available can be overwhelming. However, when it comes to near-universal performance, there\u2019s nothing quite like a perfluoroelastomer o-ring (FFKM)<\/a>.<\/p>\n

Perfluoroelastomers are the elastomeric form of polytetrafluoroethylene (PTFE<\/a>) \u2014 itself a versatile and popular material for multiple applications ranging from electrical insulation, heavy equipment, industrial piping, medical, semiconductor, food manufacturing and packaging, and environments where heavy and harsh chemicals are used. Because perfluoroelastomers have a fluorinated backbone (and higher fluorine content over FKM<\/a>), the material gains elasticity. They are the most chemically resistant elastomers available and can resist extremely high temperatures. Additionally, a perfluoroelastomer o-ring will have high resistance to steam, various solvents, ozone, and weathering.<\/p>\n

Because of these advantages, perfluoroelastomer o-rings are the ideal choice for chemical processing applications, aerospace, oil and gas exploration, semiconductors, paint and ink production, water and irrigation, life science and medical, and food manufacturing and processing.<\/p>\n

Ultimately, a perfluoroelastomer o-ring or seal\u2019s performance will depend on the application itself, as the material can vary widely. It\u2019s important to discuss your specific application<\/a> with an application engineer, but we\u2019ve identified a few particular compounds below to give you an idea of the options available.<\/p>\n

High-Performing Perfluoroelastomer O-Ring Compounds<\/h2>\n

Markez\u00ae<\/h3>\n

If you\u2019re purchased or worked with perfluoroelastomer o-rings before, you\u2019re likely familiar with major brands such as DuPont Kalrez\u00ae and Greene Tweed Chemraz<\/a>\u00ae. If so, you\u2019re also probably familiar with their high costs. At Marco Rubber & Plastics, our independent industry position has enabled us to develop Markez<\/b><\/a> \u2014 a more valuable alternative to these materials that maintains the same performance level in demanding applications. Here are a few popular Markez compounds and what you should know about them.<\/p>\n

Markez Z1028 <\/b>\u2014 Z1028 is one of our most popular compounds for perfluoroelastomer o-rings and seals due to its broad chemical and temperature resistance (rated up to 320\u00baC or 608\u00baF). It has nearly universal chemical compatibility<\/a>, making it ideal for countless chemical applications while also providing a long service life in applications thanks to its low compression set.<\/p>\n

Markez Z1352<\/b> \u2014 Another near-universal and chemically resistant perfluoroelastomer, Z1352 provides enhanced chemical resistance to strong acids and hot amines (rated up to 200\u00baC or 392\u00baF) as well as steam (rated up to 300\u00baC or 572\u00baF). Because of this, it has broad applications across the chemical, petrochemical, mechanical, aerospace, and semiconductor industries.<\/p>\n

Markez Z1321<\/b> \u2014 This compound was designed for extreme low-temperature environments, such as valves and pumps stored at subzero temperatures (oil and gas, chemical industry, etc.). Its minimum operating temperature is -45\u00baC or -49\u00baF. In addition to its low-temperature resistance capabilities, Z1321 was specially formulated to provide high resistance to a broad range of chemicals. And with low permeability, it is less prone to swelling \u2014 leading to longer service life.<\/p>\n

Markez Z1400<\/b> \u2014 In environments with extremely high temperatures and even harsh solvents, performance counts. That\u2019s why we developed Z1400 \u2014 one of the most thermally resilient perfluoroelastomer o-ring compounds available. Featuring a best-in-class high heat resistance of up to 335\u00baC or 635\u00baF, Z1400 also provides a low compression set and high chemical resistance. But best of all is that it retains these properties over time, providing you with long-lasting performance. Note that because of its properties, additional production time may be needed.<\/p>\n
