products among our customers, which we believe will be an ongoing trend.” The TPE is a 71 Shore A formulation that provides critical application performance such as weldability, kink resistance, and tensile strength comparable to other medical tubing materials, including silicone and standard TPEs. The new grade is certified for USP Class VI and ISO 10993, and is manufactured in the US with global commercial availability.
Concentrates Avient’s Mevopur Healthcare Bio-based Polymer Solutions, launched in 2021, include colour and ad- ditive concentrates based on polymers with 70-100% bio-content to help reduce carbon footprint. Available in pre-coloured formulations, they offer a sustainable drop-in replacement for fossil-based grades. To support its sustainable portfolio, the company
also recently introduced its PCF Calculator. “This cutting-edge tool, which is third-party certified by TÜV Rheinland and aligns with the ISO 14067:2018 standard, offers an important data point for the carbon footprint of Avient’s materials so customers can better understand the environmental impact of products, meet sustainability goals, and navigate the complex landscape of reducing carbon emissions,” the company reported. Antimicrobial additives can be added to
compounds to prevent growth of microbes on surfaces of parts in healthcare applications ranging from hospital beds to devices, although regula- tions governing these additives depend on the geographic region and the end-use. “There is an increasing focus on reduc-
ing microbials and fungi in the healthcare industry and other markets. However, customers and providers face challenges in meeting performance and efficacy expectations, as well as perceived barriers related to processabil- ity and pricing,” says Mitchell. Educating customers in this area is a focus, he says. Avient’s Cesa Withstand additives include
organic and inorganic ingredients to inhibit the growth of bacteria, mould and fungi on the plastic surface. Two new available grades of Cesa With- stand for TPU film can meet antibacterial and anti-mould protection needs of medical beds as well as uses outside of healthcare. The effective reduction of bacterial activity that can be achieved on TPU film laminated plastic and/or textile surfaces has been confirmed in extensive testing to international standards, including JIS 2801. The additives have also passed strict anti-fungus testing according to JIS Z 2911, Avient reports. The masterbatches are currently manufactured in Asia and are commercially available globally.
Preventing static charge Ampacet’s new ProVital + Permstat is a non-migra- tory antistatic masterbatch that provides perma- nent antistatic properties to polyolefin films used in pharmaceutical applications, such as packaging for powdered pharmaceutical ingredients. The antistat is added to the external layer of packaging films, so that electrostatic charges can dissipate. Preventing plastic from building up an electro- static charge is also crucial in medical electronic
Raumedic expands products and manufacturing
Raumedic, a global supplier of polymeric tubing and related products headquartered in Germany, launched a new effort in late 2023 to directly supply the biopharmaceutical manufacturing and life-science sectors, after more than a decade as an exclusive supplier. It extended its portfolio for biopharmaceutical fluid processing
products and launched a new brand for biocompatible tubing. It also announced it was expanding its global headquarters in Helmbrechts, Germany with a new ISO-7 clean room manufacturing facility. The company uses a range of materials (silicone, TPEs, PVC, and
fluorinated ethylene propylene) in its biocompatible fluid processing tubing. The company also makes polycarbonate connectors and prefabricates tubing sets.
