Britec’s Qd²-Liquid Carrier System boasts improved particle distribution in the polymer that supports higher pigments loadings-reducing use rates, and more. 

A line of custom liquid colorants offered in a unique proprietary liquid carrier is newly available from Britec Solutions, Tyler, Texas. The new Qd² -Liquid Carrier System has been shown to   provides multiple attributes in injection molding, blow molding and extrusion of polyolefins and styrenics. The Qd² carrier system was developed to provide improved particle distribution in the polymer that support higher pigment loadings--reducing use rates; deliver superior suspension properties to eliminate hard settling of pigments; remove processing concerns such as screw slippage; and promote cost savings.

Testing and case studies have established that when used in PP, the Qd² carrier creates nucleation, resulting in cycle time reduction. In some cases, it has the potential to reduce or eliminate the use of a nucleating agent. Colorants in the new carrier used by a Texas molder of PP caps and closures yielded a 5% cycle time reduction and 12% overall cost savings that resulted from the lower use rate needed.

An Ohio manufacturer of injection molded 5-gallon HDPE pails and lids compared the Qd²- Liquid Carrier System against their existing pellet color concentrate on a blue and white. production. The company realized a 5-second reduction in cycle time, reduced part warpage and quicker color change with colors formulated with the Qd² system.

A North Carolina injection molder PP outdoor patio furniture recently reported that not only were they able to reduce their let down ratio from 1.65% to .8%, they also achieved improved color dispersion and improved physical properties. This was achieved using BSI-105-1L, an 82% Ti02 white loaded liquid color using the Qd²- Liquid Carrier System.


  • PBT & PET Polyester: Part 2 The Performance Factor

    All things being equal, PET will outperform PBT mechanically and thermally. But the processor must dry the material properly and must understand the importance of mold temperature in achieving a degree of crystallinity that allows the natural advantages of the polymer to be realized.

  • The Importance of Melt & Mold Temperature

    Molders should realize how significantly process conditions can influence the final properties of the part.

  • The Strain Rate Effect

    The rate of loading for a plastic material is a key component of how we perceive its performance.
