On occasion, Joule RHB products can also be used in bottle polymer destined for water applications, but this usage decision depends on the application tolerance to color which must be determined via marketing specialists prior to any trials. The proprietary ColorMatrix technology has been shown to deliver superior energy saving at bottle blowing whilst at the same time imparting an attractive light blue-shaded color to the preforms (and bottles) without contributing to bottle haze. Re-establishment of the toner package will be required to achieve proper resin color.
