Processing Nylons on Blown, Cast And Bi-ax Equipment

Nylons (or polyamides) are important thermoplastic materials, which are commercially produced and processed for many applications. Some of the different Nylons are: Nylon 46, Nylon 66, Nylon 6, Nylon 6/66, Nylon 69, Nylon 610, Nylon 612, Nylon 11, Nylon 12, Terpolymer, Aromatic, Slow Crystallizing, and Amorphous Nylons. This presentation focuses on processing of Nylon 6, Nylon 6/66, Nylon 612 and their blends on different equipments such as Blown (air or water cooled), Cast or Bi-ax annular processes. Properties of single & multilayer film, methods of annealing and applications are also presented. 

Primary Topics: 
• Fundamental properties of Nylon 6 with comparison to other Nylons (46, 66, 6/66, 11, 612….). 
• Nylon film fabrication by Blown (air or water cooled), Cast and Bi-ax annular processes. 
• Annealing: Correlation of the Equipment and Process (Temperature and RH) to molecular orientation in the Nylon film during Annealing. 
• Applications: Thermoforming, Non-Forming, VFFS, HFFS, High barrier shrink films (meat & cheese), Vacuum bags, Sausage casing and Lidding film.
