Equipolymers (equipolymers.com) unveils its new BISNEINEX™ polyethylene terephthalate (PET) resin, an innovative Bisphenol-A free solution that is designed for large bottling applications including the home and office delivery (HOD) water bottle market. BISNEINEX offers converters a new, cost effective solution with no impact on raw material cost and potential improved processing cost conditions due to lower energy usage for large container sizes including 5 gallon and 20 liter applications. The resin will be available in limited quantities 4Q13, with expanded production targeted for 2014.

BISNEINEX is optimized specifically for injection molding (IM) and stretch blow molding (SBM) processes (two stage process) as well as for injection stretch blow molding (ISBM) (one stage process) production of large volume containers (>3 liters), which require thick-walled pre-forms and thus reduced crystallization rate. Relative to standard PET this novel resin, currently in final application testing, provides a number of improved process and bottle performance benefits including:

  • Large processing window due to reduced recrystallization behavior
  • Excellent bottle thermal stability (low shrinkage)
  • Exceptional color in the final application
  • Improved drop test and top load performance
  • BPA-free solution for 5 gallon and other large volume containers

“The newest addition to our portfolio, BISNEINEX, demonstrates our commitment to delivering the innovative PET solutions that our customers demand. It is a truly unique material that helps our customers move from polycarbonate to PET in a cost effective manner while meeting regulatory and consumer demands for a BPA-free plastic,” says Naser Al Dousari, chief operating officer, Equipolymers.

“As an alternative to polycarbonate (PC) in the 5 gallon application, BISNEINEX maintains good aesthetics while eliminating any regulatory or consumer issues related to existing and developing bans of bisphenol-A. As a benefit for the manufacturer, it requires very minimal changes to existing manufacturing processes, and can be used on PC lines with only minor modifications to the equipment,” says Antonello Ciotti, commercial director, Equipolymers.
