Want to learn more about Tecnoflon® FKM Low Temperature grades? Consider this.

According to Solvay:

“Tecnoflon® FKM Low Temperature grades are a wide portfolio including ionic and peroxide curable grades with TR10 range from -19°C to -40°C. They are specially designed for sealing solutions in oil drilling in cold environment as well as in the latest automotive engine technologies, like LPG, CNG and high-performance fuel injection systems.

“The VPL Peroxide Curable grades are able to withstand the most stringent specifications for automotive and oil field applications, with TR10 down to -40°C and superior chemical resistance compared to standard low temperature FKM. 


Broad range of temperatures with no sacrifice in performance.

“Tecnoflon® Low Temperature FKMs (VPL series) are designed for demanding sealing applications where they face temperatures as low as -40°C and aggressive chemicals found in Automotive, Oil & Gas and Aerospace environments.

Processing

Readily processable: Tecnoflon® Low Temperature FKMs may be handled by traditional rubber processing methods.

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.”
