A new family of liquid colors from Clariant Masterbatches has a non-mineral-oil carrier that makes them suitable for extrusion blowmolding of high-density polyethylene (HDPE).

Until now, plastics-processing problems associated with conventional carrier oils severely limited the application of liquid masterbatches in HDPE blowmolding because the mineral-oil carrier caused parison stability problems, and screw slippage hindered color distribution.

With the new Clariant Masterbatches liquids, processors can use as much as 2.5 per cent without affecting screw performance. Other problems associated with using conventional liquid carriers — for example, issues with label adhesion, printability, sidewall stress cracking — are effectively eliminated.
