Readily processable

Tecnoflon® Peroxide Curable 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.

Tecnoflon® Peroxide Curable fluoroelastomers exhibit superior resistance to a wide variety of chemicals coupled with excellent processability, optimum compression set and good flexibility at low temperatures.

Key features

• Low post cure
• Superior mold flow
• Lack of mold fouling
• Excellent mold release
• Good metal bonding

Some Tecnoflon® Peroxide Curable grades are FDA compliant (vol.21 - §177.2600):

• P 757-P 959 (n.127)

Tecnoflon® P 757 and P 959 Peroxide Curable are registered in the FDA Inventory of Effective Premarket Notifications for Food Contact Substances. They can be compounded so that the finished gaskets or seals can be used in food processing equipments.
