disinfection methods. The coloured compounds and colorants are targeted for applications such as dental scalers, surgical robots, medical stock and shapes, and portable cardiac monitoring devices. Maintaining good colour stability under these conditions can help reduce the frequency of single- use articles in these applications, the company said. The compounds have been formulated with materials that have been successfully tested for ISO 10993 biocompatibility, Avient reported. Avient’s Mevopur Healthcare Colorants and

component. PPSU was also used in the power control enclosure. The system has been success- fully laboratory-tested to survive a minimum of 100 autoclave cycles. A new compound from Syensqo is Radel PPSU
Echo RP, which uses mass-balanced materials to help lower the carbon footprint of medical devices. The compounds align with sustainability initiatives in the healthcare industry and are available globally. The company reported interest from customers in Asia and the Americas as well as strong demand in the EU. “The mass-balance solution is a drop-in replacement, as the formulation remains the same. However, since the grade name differs, some level of registration may be required. We recommend customers verify based on their specific regulatory requirements,” the company said. Syensqo’s Udel polysulphone (PSU) polymers
are also used in medical devices and other applica- tions, where they offer high strength and rigidity, resistance to cracking even at elevated tempera- tures, and the ability to be sterilised. The company announced in November 2024 that it had expand- ed PSU production at its Marietta, Ohio, US facility by more than 25%. “Since we embarked on this expansion journey for our sulphone polymers business three years ago, the trend towards higher performing materials with a balanced level of strong mechanical, thermal and chemical proper- ties has continued to grow,” said Peter Browning, President Specialty Polymers at Syensqo.

Formulations, as well as Mevopur Healthcare Functional Additives, are part of a portfolio made with raw materials pre-tested to meet healthcare standards, under controlled manufacturing condi- tions and with robust change control management beyond the Chemical Abstracts Service (CAS) identification number, the company reported. Recent developments in the portfolio include pre-coloured white and black formulations for PS and PP well plates used in polymerase chain reaction testing equipment. “These white and black formulations help maintain optimised signal transmission and minimise crosstalk that could lead to faulty results in quantitative fluorescence testing. The materials are produced under a third-party certified ISO 13485:2016 quality management system and backed by comprehensive change control of raw materials, formulation, and manufacturing stand- ards to enable consistent batch-to-batch quality,” said Volker Dickfeld, Senior Marketing Manager Healthcare Global for Color & Additives at Avient. Americhem announced in September 2024 the
introduction of its ColorRx compounds and masterbatch in a variety of standard colours and base resins to the European market. Custom colour matching and development are also available. “We’re furthering our ‘global reach, regional focus’ by extending Americhem’s capabilities to meet increasing European healthcare industry demand for high quality polymer materials. We stand at the forefront of medical device market trends, healthcare application innovation and sustainable solutions,” said Barto DuPlessis, Vice President and General Manager, Europe. “Our masterbatch and compounding excellence for advanced surgical instrumentation, robotic-assisted surgery, drug delivery, catheters, hearing aids and more lines up perfectly with the needs of the European healthcare market.” The company said that ColorRx polymers will be
produced in one of three ISO 13485 and cGMP compliant facilities throughout the world, and that the line offers RoHS and REACH compliant formulations.
