KRAIBURG TPE has launched a new series of thermoplastic elastomers (TPEs) for tubes and hoses used in sanitary and drinking water applications.
These innovative products already meet the stricter evaluation criteria for plastics and other organic materials in contact with drinking water established by the German Environment Agency (KTW-BWGL standard), which will become binding for TPEs from March 2025.
The compounds are characterized by easy processability and provide tubes and hoses with extremely smooth surfaces, considerably improved mechanical properties and excellent kink resistance.
Six Hardness Grades Ranging from 70 Shore A to 40 Shore D
“
With our new THERMOLAST® DW/H2 series, we are supporting customers who supply the market for sanitary and drinking water tubes and hoses in their effort to meet the stricter KTW-BWGL standard. At the same time, we have set a considerably higher standard for the performance of compliant TPE compounds,” says Hartmut Arheidt, market manager industry at KRAIBURG TPE. “
The innovative materials technology leads to tubes and hoses that have considerably improved tensile strength, tear resistance and elongation at break as well as excellent kink resistance.”
The unique new THERMOLAST
® DW generation replaces the products in the previous DW/H series and is currently available in six hardness grades, ranging from 70 Shore A to 40 Shore D. Easily processable on conventional extrusion lines for polyolefins, the compounds are suitable for efficient manufacturing of cold water and warm water tubes and hoses, providing up to 50% better mechanical properties and good adhesion to PP.
At the same time, the TPE compounds also provide the necessary resistance to the growth of microorganisms in accordance with EN 16421 (formerly DVGW W270) due to their extremely smooth surfaces and have no impact on the odor, taste or clarity of water flowing through the tubes and hoses.
Explore in detail about the characteristic features of building blocks of Thermoplastic elastomers (TPEs) as well as the processing methods and conditions involved in TPE manufacturing.
Suitable for Shower Tubes, Pressure Hoses and Food Hoses
The
THERMOLAST® DW/H2 compounds expand the potential applications for TPEs in this market segment and are particularly suitable for shower tubes, pressure hoses and food hoses as well as for supply tubing in dishwashers and washing machines. They have been developed in close cooperation with customers.
“
Test reports on compliance with the regulations of the new KTW-BWGL are also available to us,” adds Hartmut Arheidt. “
They confirm that the materials are generally suitable. We can gladly provide materials for sampling inspections to customers and prospective customers and partners at any time.”
