Ampacet has introduced its ProVital and ProVital+ range of masterbatches for healthcare applications
derived from castor bean oil. Rilsan MED PA 11 is formulated with 65% glass fibre, giving it a tensile modulus of 18.5 GPa. The company suggests that this tensile strength might make the material a suitable candidate to replace metal in surgical tools. Arkema claims its Rilsan MED PA 11 withstands
doors in 2021 was Pharmapack Europe, in Paris in October. Sustainability continues to be a focus, and selling point, among newly launched products.
New products Here Avient announced two additions to its Mevopur line of medical-grade materials for pharmaceutical packaging and medical devices, which it claimed could help customers reach sustainability goals more quickly. The medical- grade materials are produced according to ISO13485-2016 protocols and supported by testing to ISO 10993-1, USP, European Pharmaco- peia and ICH Q3D guidelines. Avient also demonstrated colour and additive
masterbatches based on a PE carrier that is manufac- tured using non-fossil feedstocks with a bio-based content up to 95% but which can be processed the same way, and recycled in the same recycling channels, as conventional fossil-based polyolefins. For customers who prefer ready-to-use solutions, Avient also announced Mevopur pre-coloured formulations, also based on bio-derived PE. In 2021, masterbatch manufacturer Ampacet
introduced its ProVital and ProVital+ range of masterbatches for healthcare applications. ProVi- tal+ is formulated with raw materials pre-tested to European Pharmacopeia section 3.1 and with biocompatibility according to ISO 10993 stand- ards. In 2022, Ampacet has added ProVital+ Colors to its portfolio: a range of medical-grade colours specifically designed for pharmaceutical packag- ing, medical devices and in-vitro diagnostic equipment. Arkema has introduced a new polyamide 11 for medical applications which also boasts sustainabil- ity credentials. Rilsan MED PA 11, part of Arkema’s Advanced Bio-Circular materials portfolio, is based on the company’s amino 11 chemistry, which is

repeated gamma, steam, E-beam, and EtO sterilisa- tion cycles and exposure to harsh chemicals. Biocompatibility has been assessed according to USP Class VI and ISO 10993-4, -5, and -10 stand- ards. Rilsan MED PA 11’s sustainability credentials include a climate-change impact as much as 50% lower than competitive fossil-based polymers and a reduction in the depletion of fossil fuels, says Arkema. The polymer is recyclable, most effectively when it is processed through Arkema’s closed- or open-loop Virtucycle program. Also new in the field of engineering polymers for medical applications in 2021 was a portfolio of materials from DSM. The family of medical-grade polymers includes Arnitel Care polyester-based thermoplastic elastomer (TPC), Arnite Care polybutylene terephthalate (PBT), and ForTii Care polyphthalamide (PPA). The materials are intended for use in a range of non-invasive medical devices and meet or exceed FDA food-contact require- ments, ISO-10993, and USP Class VI guidelines, according to the manufacturer. Arnitel Care L225E, L140E and L345E are grades
that offer breathability, durability and chemical resistance and are therefore intended for applica- tions including films, tubing and soft touch wear- able medical devices. Arnitel Care T1U has high purity, mechanical strength, low moisture uptake and offers chemical resistance. This is suggested for durable medical device components including inhalers and minimally invasive surgical tools. ForTii Care P1G6 offers mechanical strength,
stiffness, high-temperature performance and chem- ical resistance, and is intended for metal replace- ment particularly in minimally invasive surgical tools. “Improving health and quality of life around the world is a core pillar of our business,” said Shruti Singhal, President of DSM Engineering Materials “With our customers increasingly leveraging our advanced material solutions to improve the performance and sustainability of various medical devices, we are now taking the next step as we launch a portfolio of materials rigorously tested to adhere to the highest global quality and safety standards for medical applications.” In November 2021, Covestro launched a group of durable materials for medical device housings
