Chapter 1: Techniques

This chapter will focus on the techniques used in the production and processing of FFKM.

1.1 Polymerization Techniques

• Free Radical Polymerization: This technique involves the use of free radicals to initiate polymerization of the monomer, tetrafluoroethylene (TFE).
• Suspension Polymerization: This technique involves suspending the monomers in a liquid medium, which allows for better control of the polymerization process.
• Emulsion Polymerization: This technique involves the use of emulsifiers to create a stable emulsion of the monomers in water.

1.2 Processing Techniques

• Extrusion: FFKM is often processed using extrusion techniques to produce shaped parts like O-rings, seals, and gaskets.
• Molding: Molding techniques allow for the creation of complex geometries in FFKM components.
• Calendering: This process involves passing the FFKM material between rollers to create a flat sheet.

1.3 Curing Techniques

• Peroxide Curing: This technique utilizes peroxides to initiate the crosslinking of the polymer chains.
• Radiation Curing: This method involves exposing the FFKM material to high-energy radiation, like gamma rays or electron beams, to induce crosslinking.
