TPE/TPU
Quality, Safety, Reliability KRAIBURG TPE HAS BEEN WORKING IN THE MEDICAL DEVICES, PHARMA PACKAGING AND IN VITRO DIAGNOSTICS INDUSTRIES FOR MORE THAN 10 YEARS AND HAS COLLECTED A WIDE RANGE OF EXPERIENCE AND SKILL SETS IN THAT TIME.
A
s a member of the council that drafted the VDI Guideline 2017 for Medical Grade Plastics, which defines the common standards for materials sold, the Germany-based thermoplastic elastomers manufacturer has helped increase the safety of end products for patients and practitioners alike. Here, EPPM speaks with KRAIBURG TPE Product Manager Dr Thomas Wagner to discover what this means for the market, the industry, and the environment. WHAT ARE TPES CURRENTLY DOING FOR THE MEDICAL PLASTICS INDUSTRY? In contrast to other industries, TPEs did not enter as grip materials or simple design elements. In the market of medical devices, pharma packaging and in vitro diagnostics, TPE was from the beginning targeted to either replace existing elastic materials or open new doors in device concepts by the new possibilities it offered in material behaviour and processing. For example, TPEs are used for sealings, plugs, closures, valves or membranes in the medical sector, and each day new ideas for applications are added.
HOW DOES THE VERSATILITY OF PRODUCTS ALLOW TPES TO TRANSCEND SECTORS AND WHAT CAN WE EXPECT THE PRODUCTS TO CONTINUE DOING IN THE FUTURE? The thermoplastic elastomers of KRAIBURG TPE are used in the automotive, consumer and medical industries, amongst others. As KRAIBURG TPE is a leading specialist in this material class, we have developed different materials offering custom-engineered solutions for requirements special to each market. We focus on demanding applications for flexible applications and achieve reliable adhesion to many different thermoplastics in two-component injection moulding. And we realise high material quality and purity in combination with high levels of haptic and colouring. Our success is based on customer and application engineered co-operation and a customer-focused way of working. HOW ARE TPES CONTRIBUTING TO NEW DEMANDS IN SUSTAINABILITY, THE CIRCULAR ECONOMY, AND ENVIRONMENTAL SOLUTIONS? In general, the thermoplastic elastomers of KRAIBURG TPE can be recycled almost up to 100 per cent. Due to uncured polymer chains, it is possible to melt and reshape thermoplastic elastomers again and again. This characteristic allows customers – as long as there are no regulatory obstacles – to trace the thermoplastic elastomers back to the manufacturing process. Therefore, customers save material, can produce at shorter cycle times, and help preserve the environment in even more ways. In the medical sector, however, recycling is seen differently, as the market has higher regulatory limits and is quite often based on single-use parts. KRAIBURG TPE is

certified to ISO 9001, ISO 14001, and ISO 50001, and one of the central targets of our environmental management, as well as of our employees, is the reduction of waste and emissions.
HOW IS THE COMPANY COOPERATING WITH ACADEMIA/NGOS/ AUTHORITIES IN ORDER TO MEET ITS BUSINESS AND ENVIRONMENTAL TARGETS? The medical market is authority driven. As opposed to other markets, there are strict and clearly enforced laws to be fulfilled. The main driver is patient safety – hence the single-use preferences. These are even more important than environmental issues – both of which we take very seriously here at KRAIBURG TPE. We offer a unique service package which guarantees a maximum of quality, safety and reliability for the market.
