Peroxide curable fluoroelastomer compositions and articles made therefrom are disclosed. The compositions contain 5 to 45 weight percent, based on total weight of all fluoroelastomers present in the composition, of a blend of dynamically cured fluoroelastomer particles in an uncured fluoroelastomer. The compositions are unfilled, but have tensile properties adequate for many end use applications and are particularly useful as seals in semiconductor manufacturing equipment.

Peroxide curable fluoroelastomer compositions and articles made therefrom

Laminates of low swell elastomer, non-elastomeric fluoropolymer, and elastomer provide an excellent combination of flexibility and fuel permeation resistance.

Fluoropolymer laminates

Laminates of fluoroelastomer, non-elastomeric fluoropolymer and non-fluorinated elastomer provide an excellent combination of flexibility and permeability resistance.
