Black hues Ampacet has introduced its Natura Jet black masterbatch for injection moulding, which it says enables OEMs to achieve deep black hues in durable goods and consumer electronics The company says it “harnesses naturally derived pigment to deliver unmatched jetness in injection-moulded parts”. A sustainable alternative to traditional petrole- um-based carbon black, Natura Jet claims to deliver superior jetness over other bio-based options and is compatible with resins including PE, PP, PET, PC, PA, ABS, PLA, and TPU. Tailored for injection moulding in durables, consumer electron- ics, housewares and footwear, it helps OEMs raise sustainability without trade-offs in aesthetics or performance. “Natura Jet offers brands a true black that’s as kind to the planet as it is bold on the shelf,” said Mercedes Landazuri, market insight manager at Ampacet.

Orange marking Lanxess presented a range of pigments and colorants at K2025, for a variety of applications. For visual orange marking, it offers two comple- mentary products: Macrolex Orange HT and Bayplast Orange TP LXS 51137. Macrolex Orange HT allows plastics to be permanently coloured in RAL 2003 orange. It is a soluble organic dye with high heat stability, lightfastness, weather resistance, colour strength and brilliance. Unlike most conventional dyes, it is suitable for engineering plastics, which often require colorants that can withstand high process- ing temperatures. Its high colour strength makes it cost-efficient for manufacturers. Bayplast Orange TP LXS 51137 (Pigment
Orange 68) is also designed for high-voltage and
other engineering plastic components like hous- ings of outdoor power tools. It has good weather resistance and durability, so it suited to long-lasting outdoor and safety-relevant applications, especially when exposed to UV and other extreme conditions. Its robust properties ensure that parts maintain their safety-critical orange coloration. The use of technical plastics in high-tech
applications requires pigments with high heat stability. The Colortherm brand features a range of synthetic red iron oxide pigments that provide better thermal stability than comparable pigments as they are made using the proprietary Laux process, in which the pigments are heated to 800°C. As a result, the micronised pigments show no visible colour shift even at high application temperatures and can be processed without problems at over 300°C.
Tech upgrade Grafe has commissioned three new Arburg Allrounder 270 S compact injection moulding machines at its Color Design Center in Blankenhain. The new machines, costing around €250,000,
replace three older machines that masterbatch manufacturer Grafe used to produce samples and test specimens. “The new machines operate more energy-effi-
ciently, are easier to operate and feature a unified control concept,” said Lars Schulze, head of R&D product development at Grafe. “In addition, we can now process high-temperature plastics at our Blankenhain site.” The new machines improve processes in the technical centre and make daily operations easier for colourists, says Grafe. The modernisation of the technical centre is part
of Grafe’s ongoing commitment to sustainably strengthen the Blankenhain site. It plans further investments in the production process and ware- house management this year – with some already
