Kalrez® vs. CanRez™: Performance, Availability, & Affordability

Updated: Dec 5, 2023

In the world of industrial applications, selecting the right materials for seals, gaskets, and O-rings is crucial to ensure optimal performance, reliability, and cost-effectiveness. For extreme applicational requirements, perfluoroelastomers (FFKM) have gained significant recognition for their outstanding chemical resistance, high-temperature stability, cleanliness, and reliability. Two popular contenders in this arena are Kalrez® and CanRez™. While DuPont’s Kalrez® has long held a reputation for quality, there's a rising star on the horizon that promises to outshine its predecessor - Canyon’s CanRez™ O-rings, gaskets, and custom parts. In this blog post, we'll delve into a comprehensive comparison between Kalrez® and CanRez™, highlighting why CanRez™ emerges as the superior, more cost-effective, readily available, and efficient option.

Kalrez®: The Established Standard


For years, Kalrez® has been the go-to choice for demanding applications, known for its exceptional chemical resistance, high-temperature stability, and excellent mechanical properties. It has proven itself in industries like aerospace, semiconductor manufacturing, and pharmaceuticals, where reliability is paramount. However, this reliability often comes at a premium price, and the lead times for Kalrez® components can be lengthy.


Introducing CanRez™: The Game Changer


CanRez™, Canyon Components premium line of FFKM materials, is causing a stir for all the right reasons. This innovative line of materials aims to provide comparable performance to Kalrez®, but with distinct advantages that make it a compelling alternative:


  • Cost-Effectiveness: One of the most significant advantages of CanRez™ is its affordability. Traditional materials like Kalrez® can strain budgets, especially for large-scale operations. CanRez™ offers a more cost-effective solution without compromising on performance, making it an attractive option for businesses looking to optimize their expenses. In fact, CanRez™ parts are often more than 30% cheaper than the Kalrez® equivalent (depending on the material blend, post processing needs, and geometry requirements).


  • Equal Performance: CanRez™ doesn't just promise comparable performance to Kalrez® – it delivers. Its chemical resistance, temperature stability, and mechanical properties are on par with, and frequently better, than the established standard set by Kalrez®. This means that industries seeking top-notch reliability and quality can transition to CanRez™ without sacrificing their operational integrity. For a great example, compare the capabilities of CanRez™ CP75BK01 to Kalrez® 4079.


  • Shorter Lead Times: Unlike Kalrez®, which often requires substantial lead times for manufacturing and delivery, CanRez™ is designed for efficiency. Canyon Components stocks thousands of pieces of standard O-ring sizes and the CanRez™ production process allows for quicker turnaround times, which can be a game-changer in situations where downtime must be minimized. CanRez™ is even rapidly available in custom geometries!


  • Innovative Manufacturing: CanRez™ is developed using cutting-edge manufacturing techniques that allow for tighter quality control and consistent material properties. This translates to fewer variations in the final product, ensuring uniform performance across different applications.


  • Eco-Friendly Approach: CanRez™ places a strong emphasis on sustainability. Its production process incorporates environmentally friendly practices, making it an ethical choice for businesses striving to reduce their carbon footprint.


Making the Switch: Factors to Consider


While CanRez™ offers undeniable advantages, making the switch from Kalrez® requires careful consideration. Factors such as the specific requirements of your application, the materials' compatibility with the substances they will come into contact with, and long-term performance expectations should all be taken into account.


In conclusion, the comparison between Kalrez® and CanRez™ clearly indicates that CanRez™ O-rings, gaskets, and custom parts are a readily available, more affordable, and high performance option for a wide range of industrial applications. Its ability to match the performance of Kalrez® while simultaneously offering cost savings, faster lead times, and environmental consciousness makes it a compelling choice for businesses aiming to optimize their operations. As industries continue to evolve, embracing innovative solutions like CanRez™ could be the key to staying ahead of the curve.
