Video - Basics of Fluoroelastomers (FKM)
Fluroelastomers, also known as FKM are a class of synthetic rubber designed for very high temperature operation with excellent levels of chemical resistance. FKM is not a single entity but a family of fluoropolymer rubbers. FKM, sometimes referred to as Viton®, is a registered trademark for fluroelastomer by DuPont.
Fluoroelastomers differ from other elastomers in that it has fluorine linked to the polymer backbone.

Transfer Retention Downtime can be Costly
Often times people think that a seal is just a seal or that the materials don't matter, but this is far from the truth. No two sealing materials are exactly the same and have their own unique characteristics that make one material perfect for a specific application while another could completely fail. Materials are truly the foundation of every seal and can't be overlooked when you are considering what kind of seal to use.

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

CNC Machining Seals with a Haas Automation Machine
CNC machining, which stands for Computer Numerical Control, is a manufacturing process in which pre-programmed computer software dictates the movement of tools and machinery.
The process can be used to control a range of complex machinery, from grinders and lathes to mills and CNC routers.
But in our case, Gallagher is utilizing this process to cut both custom and standard seal profiles for our customers.

PFAS Classification Threatens Fluoroelastomer Supply
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

Food Safety Modernization Act (FSMA) and Sealing
Every year, approximately 1 in 6 people in the U.S. get sick (~48 million people), 100,000+ are hospitalized, and 3,000 die from foodborne illnesses or diseases, according to data from the CDC. Though this is largely a preventable problem, it still poses a significant public health burden.
The FDA Food Safety Modernization Act (FSMA), enacted by Congress in 2011, is "transforming the nation’s food safety system by shifting
