DAK Americas Laser+® W L44B PET
Categories: Polymer; Thermoplastic; Polyester, TP; Polyethylene Terephthalate (PET); Polyethylene Terephthalate (PET), Unreinforced

Material Notes: Product Description: Laser+® W (L44A) polyethylene terephthalate (PET) resin is a copolymer formulated for conversion to PET bottles by conventional single or two-stage processing technology.

Typical Properties: Bi-orientation of Laser+® W (L44B) by injection/stretch blow molding provides optimal barrier and mechanical properties, including superior stress crack resistance. It performs exceptionally well in the manufacture of water bottles where heat up rate and temperature profile through the wall are important. DAK has engineered Laser+® W (L44B) for water bottle use by providing a slightly lower intrinsic viscosity (IV), allowing for a gentle injection molding process, and improved acetaldehyde (AA) performance. Laser+® W (L44B) offers superior heat absorption and processing control, even at higher blow molding speeds. A relatively slow crystallization rate enables high injection molding output.

Certification: Laser+® W (L44B) is ideally suited for food packaging applications and is considered in compliance with the Food and Drug Administration (FDA) Food Contact Notification (FCN) 000635, covering PET polymers.
