Product Description
Laser+
®
W 4000 (K42A) 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 4000 (K42A) 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.
Laser+
®
W 4000 (K42A) is engineered 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 4000 (K42A) 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 4000 (K42A) 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.
