M&G PoliProtect APB


January 2010 Polyethylene Terephthalate (PET) Data Sheet


DESCRIPTION
M&G PoliProtect APB Polyester Resin is a TPA-based polyethylene terephthalate copolymer resin with both an active
oxygen scavenger and a passive barrier incorporated into the pellets. The passive barrier is protected via BicoPET™
technology which incorporates the passive barrier into the core compartment of the pellets. It is a high molecular weight
polymer with a 0.85 intrinsic viscosity (IV).


M&G PoliProtect APB Polyester Resin is designed to provide highly desirable container properties. In addition to the
active oxygen scavenger and passive barrier that provides oxygen protection and carbon dioxide retention for package
contents, it also yields containers with sparkle, high strength and toughness.

The following table provides the Parameters that characterize the grade. Some Parameters are shown with values that are
specified to fall within certain limits. Other Parameters are shown as a single value that we regard as typical of the grade.
Minor differences around this typical value will not detract from the performance of the product. All Parameters are
measured, under laboratory conditions, by the M&G analytical method shown. Different methods or conditions of
analysis may give rise to different values. Purchased material may be accompanied by a Certificate of Analysis or other
document, confirming that the product is within specified limits and is consistent with the other values for the stated
Parameters.

IMPORTANT ASPECTS OF USE IN PROCESSING

Drying
Thermoplastic polyesters such as M&G PoliProtect APB Polyester Resin can undergo hydrolysis if moisture is not
eliminated prior to injection molding leading to a decrease in molecular weight and loss in mechanical properties of the
bottle, particularly top load performance, creep and impact strength. Moisture content of the resin must be reduced to a
level of 0.003% (30ppm) or less, prior to melt processing. Drying is best accomplished in a continuous high heat
dehumidifying type air hopper dryer with a regenerative desiccant bed using -20°F max (-29°C max) dew point air.
Typical drying conditions are an air temperature of 350°F (175°C), 4 to 6 hours residence time and a minimum air flow
rate of 1.0 ft3 per minute per pound of polymer consumed per hour. If longer residence times are utilized lower
temperatures should be used. An example might be 325°F (163°C) for 8 hours residence time.

Injection molding and Stretch blow molding
Injection molding temperatures should be maintained at the minimum levels needed to produce clear quality preforms.
In addition to temperature limits, care should be taken to avoid excessive shear during injection. Typical processing
temperatures are generally between 10°C and 30°C hotter than the Melting Point Parameter indicated on the front of this
Data Sheet, largely dependent upon injection barrel dynamics such as residence time and shear.

When stretch blow molding, preforms should be heated to minimum levels needed to produce clear, quality biaxially
oriented containers. Typical preform surface temperatures are generally between 90°C to 105°C, largely dependent
upon the equipment setup and efficiency.

Addition of Colorants
If colorants are to be used with M&G PoliProtect APB Polyester Resin please contact your M&G technical
contact as some colorants have been found to be detrimental to the active portion of the oxygen barrier. Your
M&G technical contact can determine if the colorant is on the list of tested colors.
