to align in many markets in the future. “An expect- ed shift will have people moving into a new behaviour accentuating use of colours, materials and finishes that make us feel good about the future of not only ourselves but of our planet,” predicts Mercedes Landazuri, Market Insight Manager at Ampacet. “Being able to purchase materials into which waste has been incorporated is becoming a driving force moving forward,” she says. “As a result, speckled, granite and mixed-material effects work as a positive sustainability message for consumers, so we anticipate growth in demand for these types of effects.”

Grafe also presented its latest Luxury master-
batches at K2022. These combine a matting agent with a shimmer effect and colour to give injection molders an option to create different looks without tooling changes, according to Schulze. The three new three Luxury shades included Shiny Graphite (a matt black), Silky Lux-Grey (which combines grey with brown nuances), and Liquid Rosé Gold. The Luxury effects were shown in a styrene-acry- lonitrile (SAN) copolymer and used a SAN carrier to match the matrix. Other carriers can also be used, the company says, although the gloss and colour will vary somewhat depending on the matrix resin used. “We will be happy to check requests in our technical centre if the effect is desired in other polymers,” Schulze says.
Aesthetic and sustainability demands are likely Ampacet collaborated with French firm Nature-
Plast to introduce Secret Sea-Grit, a masterbatch collection made from 100% post-consumer recycled (PCR) material and aquaculture waste. The master- batches are designed for injection moulded prod- ucts for packaging and consumer goods applica- tions and are available in several “nature-inspired shades” including Bivalve Brown, Nude Nacre, Muted Murex, Softshell Celadon, Beachcomber Blue, Salty Sienna, Brackish Brown and Saltwater Sand.

Avient ‘lightens’ its heavy compounds
Avient has added new reduced carbon footprint options to its Gravi-Tech Density Modified Formulations, which are designed to mimic the appearance, weight, and feel of metal
Intended for applications such as luxury packaging and consum- er goods, Gravi-Tech grades combine thermoplastic resins and metallic fillers. Formulations can be customised to achieve up to five times the density of the base polymers and can also be coloured. “Due to the high load in the
material, Gravi-Tech has an inherent metal-like visual effect that can be adjusted by the functional filling system that is used. With some pigmentation, this effect can be

enforced,” says Hermann Fuechter, Senior Marketing and Product Manager EMEA at Avient. The new additions are targeted at end users looking to reduce carbon footprint. Gravi-Tech REC Recycled Formulations include recycled content sourced from post-industrial recycled
relationships with our suppliers, who are able to provide PIR and PCR recycling materials that have a
reliable specification,” says Fuechter. Both the Gravi-Tech REC Recycled
Formulations and Gravi-Tech BIO Bio-based Formulations are currently manufactured in Europe but are commercially available globally. �
