At the COMPAMED 2022 exhibition, HEXPOL TPE
officially launched their medical TPEs with bio-attributed content according to the mass balance principle.
Adding to their growing portfolio of materials that enable a shift away from fossil feedstocks.
Gradual Increase of Bio-circular Share
HEXPOL TPE identified mass balance as a good option for their medical customers as the resulting TPE material is a drop-in solution with identical properties. This is because monomers from renewable sources, but with the same quality and purity as those of fossil origin, are used to make bio-circular polymers (through mass balance).
HEXPOL TPE can replace the fossil polymers in their TPE compounds with the bio-attributed mass-balanced version to create a 1:1 replacement. The technical properties, chemical composition, and regulatory status of the mass balance TPE will be the same as the corresponding fossil-based material.
Annika Swanholm, medical development engineer at HEXPOL TPE, commented, “It’s important for us to support our medical customers as they address the sustainability of their products and help them make informed material choices. To be included as part of our Mediprene portfolio of medical TPEs, we must also ensure we uphold the highest levels of raw-material selection, regulatory compliance, traceability and change management

ISCC PLUS Certified
Third-party verification is required to audit the mass balance allocation and allow for correct product labelling. HEXPOL TPE’s Swedish site was among the first TPE compounders to achieve the International Sustainability and Carbon Certification (ISCC PLUS) last year.
The new materials will form part of the Mediprene portfolio of TPEs for medical applications. Mass balance versions of their Mediprene 500M standard series are available, as well as customized grades. Typical applications include airway management, face masks, resealable membranes, IV systems, seals and connectors.
Inger Haag Olsson, medical development engineer at HEXPOL TPE, added, “These mass-balanced TPEs allow customers to meet performance requirements while ensuring the regulatory status and, at the same time, working towards their sustainability goals
HEXPOL TPE can provide cradle-to-gate Product Carbon Footprints (PCF) to further inform customers. HEXPOL TPE’s PCF methodology is built upon the principles of ISO 14067:2018 for the carbon footprint of products, which is associated with the principles and requirements of ISO standards 14040:2006 and 14044:2006 for life cycle assessment. The PCF provides CO2 equivalent data per kg of TPE, calculated from raw materials and their transportation, product manufacturing and packaging.Source: HEXPOL TPE
