Kalrez Spectrum 7075 expanded on the capabilities of Kalrez 4079 by offering much lower compression set, increased seal force retention, broader chemical resistance and higher temperature stability.
Kalrez Spectrum 7075 joined the family of Kalrez Spectrum™ products designed specifically for the chemical processing industry. As a newer compound, 7075 contains enhanced physical performance properties, including very low compression set and improved seal force retention. To provide even greater sealing performance in dynamic applications where low friction is required, 7075 O-rings have a glossier finish than other Kalrez parts.

Bottling lines allow manufacturers to rapidly fill thousands of bottles perfectly making them a key element in food & beverage manufacturing facilities. While this equipment is incredibly efficient and has allowed manufacturers to greatly increase production, it offers some unique challenges for sealing solutions. Seals experience rapid and repetitive movements, challenging media, and are required to meet high purity standards often set by the FDA.
With these demanding applications and strict requirements, sealing manufacturers need a lot of expertise and specialized materials/ designs. Today we are going to highlight our Distributor Fredenberg-NOK Sealing Technologies and their brand of Freudenberg seals designed specifically for bottle filling and process industry applications.
As we mentioned in our messaging earlier this year, DuPont was in the final stages of opening a new Kalrez® perfluoroelastomer parts manufacturing facility at their Tralee Park Annex site in Newark, Delaware.
We are happy to announce that the new facility is completed and running at full capacity.
Today, we continue our series on the world’s most popular perfluoroelastomer, Kalrez.
The agenda for part two of our video series on FFKM will compare conventional elastomers vs. Kalrez®. We will take a deep dive into what makes Kalrez so special for a wide variety of industries and applications worldwide.
Since Kalrez® parts are predominately used in sealing systems, it is useful to review the basic properties of the most popular seal materials compared to the world's most well known FFKM, Kalrez®.
PFAS is a generic term referring to a group compounds that contain Carbon-to-Fluorine bonds, C-F3 and C-F21. This includes all fluoropolymers and fluoroelastomers such as FKM, FFKM, PTFE, and many others. These materials are extremely useful in critical applications due to their properties such as resistance to heat, chemicals, and environmental exposure. These important characteristics result from the strong bond between the fluorine and carbon atoms, which is unmatched in the world of polymers. PFAS-based materials are highly desirable for a number of industries and applications, including semiconductor manufacturing, lithium ion batteries, smart phones, medical technologies, and aerospace.
While there can be many excellent uses for PFAS base polymers, some PFAS chemicals have shown environmental and health drawbacks. Due to their extreme resistance to heat and chemicals, they do not break down in the environment,
The semiconductor industry is a specialty market that requires seals to work in extreme chemical and temperature environments - and these seals must block materials from entering the fluid stream.
There are several different ways for seals to accomplish this task, but the first consideration is the operating characteristics.
For static seals where no relative motion exists, the use of perfluoroelastomers, or FFKM rubber, is considered a first consideration.
Gallagher Fluid Seals is a designated distributor of
Many of Gallagher's customers use Kalrez FFKM for their equipment or processes. It's known worldwide for its effectiveness in the harshest applications - able to withstand nearly all media and extreme temperatures.
But what makes Kalrez so special? Why is it it far superior to other elastomers?
This video will dive into what makes Kalrez FFKM different than other conventional elastomers when it comes to sealing in the most demanding environments. Learn about the technical specification and the science behind the world's most popular perfluoroelastomer.
DuPont is in the final stages of opening a new Kalrez® perfluoroelastomer parts manufacturing facility at their Tralee Park Annex site, located at 322 Ruthar Drive, Newark, DE 19711.
Included in the processes and capabilities at their new facility will be the manufacture, finishing, inspection, packaging, and shipping of Kalrez® perfluoroelastomer parts. DuPont intends to begin shipping parts processed at the new facility starting in August 2023.

It's known that DuPont™ Kalrez 0040 and Kalrez 0090 are two of the most popular low temperature perfluoroelastomers in the marketplace.
Each compound has unique physical properties and can be better in certain applications. In fact, GFS engineers are often asked for compound guidance for these low temperature FFKMs.
This video discusses, at a very high level, the similarities and differences between Kalrez 0040 and Kalrez 0090.
It's known that DuPont™ Kalrez® 4079 and Kalrez® Spectrum™ 6375 are two of the most popular FFKMs in the marketplace.
Here at Gallagher Fluid Seals, we are often asked about the differences and which compound may be better for an end-user's application.
