Customized medical technology materials

High-viscosity Ultraform® PRO and medical-grade Ultradur® PRO

Ultraform N2320 003 PRO is an injection-molding grade in the product range with a higher viscosity. Thanks to its high impact resistance and stiffness, this Ultraform N grade is just right for the manufacture of highly stressed elements such as functional parts in insulin pens, atomizing devices or dry-powder inhalers. On the other hand, the grade Ultraform H4320 PRO has been tailored specifically for processing by extrusion at high ejection speeds. It is highly viscous, even more impact-resistant while also being very stiff as well as strong, and it displays good thermal stability. Its target applications are plug-in connectors, handles of surgical instruments and other components that are made from semi-finished parts.

The material Ultradur B4520 PRO is BASF’s first PBT for injection-molded applications in medical technology. Here the well-known high dimensional stability of PBT has been further improved by adding optimized shrinkage behavior, so that this product now meets the stricter requirements in terms of reproducible dimensional accuracy made on components intended for medical devices. Most importantly, this material can be easily printed on and sterilized with ionizing gamma radiation or ethylene oxide.

Comprehensive service package for medical technology

Along with its plastics from the “PRO” family (PRO: profile covered raw materials only) BASF offers a comprehensive service package that has been adapted specifically to the requirements of medical technology. Aside from support relating to applications technology, this package entails the explicit commitment that no changes will be made in the plastic formulation stored in the Drug Master File (DMF) at the FDA. All product grades of the PRO range have been shown to comply with the applicable international standards and tests for medical technology uses of plastics such as the EU, US and Japanese Pharmacopeias and DIN EN ISO 10993-5. Such tests are performed (on pellets) by independent third-party institutes.

Heat-resistant Ultrason®

With its stability at high temperatures and exceptional chemical resistance, Ultrason, too, is suitable for medical technology applications. What is more: it is transparent. In addition, most products from this range have been certified to the typical food contact and drinking water standards.
