3 Reasons Kalrez® FFKM Seals are Ideal for Medical Applications


Kalrez® is one of the best-known names in the sealing industry. Renowned for their strength, durability, and quality, Kalrez® seals are some of the most-requested products at Wyatt Seal.

For medical applications, few sealing solutions are more versatile than Kalrez® perfluoroelastomers; They’re rated to the highest standards for safety and quality.

Here are three reasons they’re ideal for use in the medical industry.


  1. Outstanding Chemical Resistance

High-performance PTFE seals can creep and cold flow when attacked by outside chemicals which eventually leads to a loss of sealing functionality. For medical use, seal viability is of utmost importance. DuPont™ Kalrez® Perfluoroelastomer (FFKM) seals are unmatched in the market in terms of chemical resistance.

Resistant to over 1,800 different chemical substances, Kalrez® seals are made to retain high levels of elasticity and recovery. They have been designed specifically to minimize swell and hold their shape even within the most extreme chemical environments. Kalrez® seals have been tested against inorganic acids, ketones, alkalines, esters, fuels, alcohols, and many other substances.

  1. Steam and Temperature Resistance

Steam-resistance is also a critical characteristic for medical seals since myriad modern medical processes, including packaging, require steam for sanitization and/or adhesion. Kalrez® seals have been designed to perform in high-temperature environments, including those where steam or hot water is involved.

DuPont™ Kalrez®perfluoroelastomer parts are best-in-class in terms of FDA-compliant elastomers. Their outstanding thermal qualities are just one of the reasons they’re ideally suited for high-test applications like those frequently found within pharmaceutical production, medical processing, and food and medical grade packaging.

  1. Always Clean, Always Safe

Medical processes must meet a very high bar for cleanliness and safety. When seals fail, products can unknowingly become contaminated with chemical solvents or even with pieces of the seal itself. Many medical packaging and production processes are pressurized which can create an unsafe environment for manufacturers themselves if the seals involved can’t be counted on.

Kalrez® perfluoroelastomer seals are the only elastomer that offers supreme chemical resistance coupled with the cleanliness standards required for pharmaceutical production. (Pharmaceuticals are subject to some of the most stringent processing regulations in the world.) Kalrez® FFKM seal products designed specifically for medical applications include safety valves, butterfly valves, granulators, safety seals, aerosol rings, and more.
