Pennacle® 66B158 is a Black Pigment Additive. During our initial development of Pennacle®, a palette of pigments and dyes were established that had little to no effect on the rate of crystallization of PET. From this, a series of industry standard colors were developed and sent to an outside lab for analysis. Free Blow experiments were conducted to evaluate the effect of Pennacle® on Natural PET resin. In two stages preforms were molded, then conditioned and free blown to evaluate blow parameters and physical properties. The results of these experiments are listed below. This palette is the basis for all Pennacle® color matches made today in PET.
