Tecnoflon® NM FKM is a fluoroelastomer copolymer based on hexafluoropropene (HFP) and vinylidene fluoride (VDF). Tecnoflon® NM FKM has been developed particularly to improve extrusion, blow molding, and rotomolding of low density polyethylene, high density polyethylene, and linear low density polyethylene as a processing aid. It is available in a free flowing powder form, is easy to handle and to dose accurately in masterbatch and/or polymer resins.

Due to its incompatibility with the majority of polymers and their fast movement in the molten flow during extrusion, Tecnoflon® NM FKM build a thin coated layer on the metal surface of the die leading to a direct improvement of the processability of the extruded polymers (stabilization of flow instabilities).

Key features

• Elimination of melt fracture (shark-skin effect)
• Reduction of die build-up
• Improvement of the surface finish with high gloss levels
• Faster production start-up
• Pressure reduction
• Higher output at constant die pressure and temperature
• Lower energy consumption

Normally a final concentration of only 100 to 1000 ppm Tecnoflon® NM FKM is sufficient to achieve the mentioned benefits.

Tecnoflon® NM FKM has been developed particularly to improve extrusion, blow molding, and rotomolding of low density polyethylene, high density polyethylene, and linear low density polyethylene as a processing aid.

It's usage is ideal for the production of blown and cast film mainly used for:

• Industrial packaging film
• Agricultural film
• (Co-extruded) food packaging film
• BOPP film
