colour and the polymer. For compounding lines, the company’s screw feeding technology with patented SmartClean technology for fast colour changeover can be used to dose the pigments. A key benefit is that continuous monitoring and adjusting can maintain the correct colour specification at the lowest possible colorant usage rate, said Doug Brownfield, Commercial
letised mono-pigment, which is available in five primary colours or in custom formulations. The colours are in a universal carrier and are designed for low usage rates using LIAD Smart microfeeding technology. Ampacet says the colorants have good hiding power and improved distribution that reduces swirls and gels. The system weighs each FluxQF mono-pigment individually and meters the mixture directly into the extruder with the base masterbatch
Director for LIAD Smart at Ampacet. The new, patent-pending SpectroMetric 6 can be used by compounders, and it has the potential to be used with profile or sheet extrusion, if these lines have adequate mixing screws, as well as with large-part moulders if their systems have enough residence time to melt and distribute the mono- pigments, said Brownfield. The equipment can be retrofitted onto existing lines. “SpectroMetric 6 technology is ideal for extru-
sion processors of recycled materials that have difficulty maintaining colour due to PCR colour variability within the same lot or lot-to-lot. The system time stamps all measurements and correc- tions during the production run which can then be downloaded for future analysis and customer QC reporting,” he said.
