Product Description
FreChem FKM fluoroelastomer gum raw FKM rubber
TDS of FreChem FKM raw gum
Fluoroelastomer was introduced in 1957 to meet the needs of the aerospace industry for a high performance seal elastomer.
Since then, the use of fluoroelastomer has expanded to many other industries, especially in the automotive, fluid power, appliance, and chemical fields.
With over half a century of proven performance, fluoroelastomer has developed a reputation for outstanding performance in high temperature and extremely corrosive environments.
