Updated FKM Durometer Chart from 3M

The first step in developing an FKM part is determining a formulation to withstand the part’s future environment. The part’s environment will dictate the physical properties required for your rubber compound. This 3M™ Dyneon™ Fluoroelastomers Formulated to Various Durometers Using N990 Carbon Black and Non-Black Molded Goods Compounds chart is an excellent starting point for developing that initial formulation.

This chart also features a “Carbon Black Comparison” table with helpful conversions for thermal and furnace black filler variances.
