Kraiburg TPE is presenting Thermolast DW H2, a series of new, plasticizer-free TPE compounds for sanitary and drinking water tubes and hoses that comply with the tightened DTW-BWGL standard (mandatory from March 2025) for organic materials in contact with drinking water. Available in five hardness degrees from 70 Shore A to 40 Shore D, they are suitable for low-cost processing on existing extruder lines for polyolefins, provide good adhesion to PP and ensure smooth surfaces with high resistance to the growth of microorganisms in accordance with DVGW W270. The range of suitable applications includes in particular shower tubes, pressure hoses and food hoses as well as supply tubing in dishwashers and washing machines.
The new Hot Water TPEs for hot water applications, compliant with the KTW-BWGL standard, are used in the environment of frequently changing water temperatures, such as seals and showerheads. As first non-cross-linking TPEs in this market segment, they also facilitate processing by their increased flowability and easy ejection. They also feature good adhesion to PP and PE as well as improved compression set at higher temperatures. Kraiburg TPE expects this technology for applications in contact with drinking water to be finally certified by the end of 2023.
Also on display: second and third generation biobased TPEs with a proportion of renewable raw materials of up to 71%, which are not in competition with the production of food or animal feed. The compounds expand Kraiburg TPE’s existing portfolio of sustainable materials for applications where manufacturers and processing companies are increasingly looking for materials solutions that significantly reduce their carbon footprint; and TPEs with higher proportions of recycled materials of up to 80% from post-industrial and/or post-consumer waste streams. Recycling Content TPEs provide an attractive environmental balance. They can be used universally and excel with high adhesive strength in multicomponent compounds with plastics such as PA, PC/ABS or PP.
“Product reliability, sustainability and efficiency are the core requirements of our customers in the plastics industry. We are determined to meet these requirements by providing TPE solutions that set new standards with regard to high performance, cost-effective processing and exemplary environmental balance,” said Oliver Zintner, CEO at Kraiburg.
