dispersion and high-quality carbon black, enables high-temperature moulding with higher line speed and no drool for applications in the petroleum and the chemical processing industries. In addition, Transcend colorants – based on polysulphone and Peek – can withstand up to 1,000 autoclave cycles and high-heat sterilisation at 150°C. The Peek grades were first launched at Medica in November 2024. The pre-coloured compounds were developed with the demands of the healthcare industry in mind, it says. Deborah Sondag, global
marketing manager for Colorant Chromatics at Avient, said: “These Peek pre-coloured compounds can give healthcare manu- facturers the flexibility and reliability they need to produce high-quality medical devices.” They are aimed at
applications such as dental scalers, surgical robots, medical stock and shapes, and portable cardiac monitoring devices.
HFFR for PP Tosaf has added a new halogen-free flame retard- ant (HFFR) for polypropyl- ene (PP), for both extrusion and injection moulding. This will enable more sustainable solutions to meet customer requirements and legal specifications, it says. FR8719PP is designed to meet the flame-retardancy requirements of PP in injection moulding and extrusion. Even at low concentrations, it helps to prevent the spread of fire

and meets stringent safety criteria in applications such as construction and auto- motive. The high dispersion of FR8719PP in injection- moulded and extruded PP-based products is one reason for its high efficiency. A relatively low dosage means mechanical proper- ties are largely retained. In addition, the low potential for dye build-up (DBU)
