Molding versatility
Tecnoflon® Base Resistant FKM may be compression, injection or transfer molded.
Compression Molding
Compression molding is the oldest and most common form of molding of FKMs.
Transfer Molding
A medium viscosity polymer is recommended. A careful consideration of cure rate is important to ensure scorch safety.
Injection Molding
Injection molding is the most demanding molding process. The injection molding grade selected should have a molecular weight distribution to achieve the best flow and good scorch safety with a very steep cure rate. Molding fouling must be minimized by using formulations minimizing process aids and metal oxides.
Extrusion
Extrusion of FKMs is used to form extruded shapes, tubing, O-ring cord, and compression molding pre-forms.
