● Outstanding resistance to aggressive chemicals;

● Outstanding steam resistance;

● Outstanding compression set even at very high temperatures;

● Processability by standard fluoroelastomer technology on convential rubber equipments.

● Price is the most expensive.

Application

O-rings, seals, diaphragms and other parts used in process industries.

MOQ
