Everything You Need To Know About FKM Rubber
Look through any manufacturing industry today, and you’ll find that rubber plays a major part in what they do. Rubber has easily become one of the most versatile materials today, and as time goes on, there’s a sense that its application will only grow.
Today, FKM rubber is amongst the most renowned and most functional types of rubber. And, many manufacturers have come to see the light and embrace it wholeheartedly. So, what is it, and why is it so popular? Let’s answer all these questions and more below.
What Is FKM Rubber?
To begin with, it is important to know that the “FKM” in “FKM rubber” stands for “Fluorocarbon.” So, whenever someone asks, “What does FKM stand for in rubbers?” it just means “Fluorocarbon rubber.”
Here, you have a type of synthetic rubber that is made from fluorinated hydrocarbon polymer. FKM rubber operates as what you call a “copolymer,” mixing with vinylidene fluoride (VDF) and hexafluoropropylene (HFP). You can also have a few FKM rubber compounds that contain the material’s reaction with other materials – a characteristic that makes FKM rubber especially flexible.
