Extruded seal are made by forcing the non vulcanized uncured rubber through an extrusion hole while it is under heat and pressure. This uncured rubber is then vulcanized, i.e. heated,to cause a chemical reaction which cures the rubber. However, the term "rubber extrusion" is used loosely to refer to many elastomers in addition to natural rubber --- elastomers such as EPDM, EPR, NBR, neoprene, nitrile (Buna-N), silicone, Viton, Kalrez, Chemraz, Aflas and urethane.
