Vibrant palette Ampacet has introduced several new colour masterbatch grades to its portfolio. One, the Kaleidoscope collection, is “a vibrant


palette of transparent colours designed to be layered, unlocking an endless array of custom hues”, it says.

“Our [CNT] compounds exhibit the first signifi-


cant measurable increase in mechanical properties of a thermoplastic compound,” said AJ Pasquale, director of operations at Insight Polymers. “Their light weight and lower loadings translate to lighter, stronger end products.”


Graphene grades Broadway has introduced a range of graphene- enhanced masterbatches called Graphenexcel. The company says it brings the advantages of


graphene to plastics manufacturers. The launch is the result of strategic partnerships with graphene suppliers. Graphenexcel uses the properties of graphene


to improve the performance of polymers used across many industries, including automotive, defence, packaging, and consumer goods. Benefits include improvements in strength and durability and the chance for product lightweighting. It is a made-to-order additive masterbatch, with formula- tions targeted to customer needs. It is compatible with polymers including polyolefins and PET. Graphene increases the tensile strength of


plastics, adding strength and durability to moulded components. This is important in applications such as in automotive parts and protective packaging. Typically, in polypropylene (PP) and polyethylene (PE) applications, a graphene loading of 0.2-0.5% can give a 10-20% improvement in impact resist- ance and tensile strength. Other benefits include: increased elastic modulus, for better performance in structural applications; weight reduction, through thin-wall- ing; improved flow during processing, for more efficient manufacturing and better part consist- ency; and better fire retardancy. “The combination of strength, conductivity, and


versatility will redefine what is possible for our customers,” said Stephen Rayner, technical director at Broadway.

“By layering these translucent colours, designers can add depth and visual excitement to a wide range of consumer products,” said Mercedes Landazuri, market insight manager at Ampacet. Compatible with polystyrene and polycarbonate in injection moulding, the eight Kaleidoscope grades have a low LDR and are ideal for applica- tions such as housewares, consumer electronics, toys, appliances and lighting. In addition, the company has introduced


ProVital+ LaserMark, a set of masterbatches for high-contrast laser marking using Nd:YAG lasers on medical devices, in-vitro diagnostic equipment and packaging systems. LaserMark 1001513-EM is a high-definition laser marking solution for dark markings on transparent/translucent, white or light-coloured PE or PP parts; 1001514-EM is an antimony-free technology, for the same purpose. The masterbatches have been pre-evaluated for biocompatibility according to ISO 10993 part 5, 10 and 23 (cytotoxicity, skin sensitization and irritation) and European Pharmacopeia (Ph. Eur.) 11th edition, monograph 3.1.3. They provide full consist- ency of formulation with a no-change policy for raw materials at CAS and commercial levels, with manufacturing under consistent process param- eters and cleanroom production to minimise cross contamination risks, says Ampacet.


Colour solutions Avient presented a range of colour and additive solutions at Chinaplas recently. “We’re committed to helping the plastics industry follow the latest regulations while enhanc- ing product performance and making manufactur- ing more cost-effective,” said Say-Eng Lee, vice president and general manager for colours and additives in Asia at Avient. Solutions at the show included: Cesa non-PFAS


process aids for various applications; Hydrocerol chemical foaming agents, which reduce material consumption, part weight, and cycle times in injection-moulded products, while maintaining surface finish and eliminating sink marks; and oxygen scavengers to enable recycling, ColorMa- trix Amosorb 4020L. It also showed two Colorant Chromatics ser- vices. Conductive Formulations, for controlled
