Tecnoflon NM

Tecnoflon® NM FKM

Tecnoflon® NM is a fluoroelastomer copolymer used as an additive in order to offer unique benefits to polymer resins, such as the elimination of melt fracture and the reduction of die buildup.
 

Processing

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.
 

Performance

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.
 

Applications

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
