Trelleborg Sealing Solutions has launched the globally compliant WaterPro portfolio of ethylene propylene diene monomer (EPDM) sealing materials suitable for everyday use with potable water systems.
Designed to meet all global regulations, WaterPro EPDM materials offer comprehensive solutions for the full range of potable water sealing applications, including heating systems, fixtures and faucets, valves and pumps, water treatment systems, drinking water filtration and smart meters, it adds.
All WaterPro materials comply with French ACS rules, US NSF/ANSI/CAN Standard 61, UK WRAS, German KTW W270, and European DIN EN 16421 P2/M2, and surpasses ASTM D6284. They are also pre-qualified to meet the forthcoming German KTW-BWGL standard, now set to be mandated in 2026 a year later than originally planned.
Trelleborg adds that customers gain a competitive advantage, integrating the materials into their applications with confidence, ensuring uninterrupted market access and a seamless transition when the KTW-BWGL regulation becomes mandatory in 2026.
“Global manufacturers benefit from the worldwide compliance of premium materials, knowing that they meet all current applicable standards wherever they sell their products,” says Adam Li, Global Segment Director Processing Industries.
“We can also help customers optimise their supply chain with unsurpassed design expertise and innovative technologies, working with their teams to develop more complex parts,” concluded Li.
All the materials are PFAs-free and can be direct injection moulded for highly automated production processes, or overmoulded as rubber-to-plastic and rubber-to-metal solutions. The entire WaterPro range features compression set performance and resistance to chlorine and chloramine disinfectants.
Tim Reski, Rubber Technology Leader, adds: “We have developed our own enhanced proprietary version of the ASTM D6284 testing standard for seals exposed to chlorine and chloramine at our innovation centre in Plymouth, Minnesota, US.”
He also added with over 1,000 hours of testing that all the WaterPro range maintained their integrity and exhibit less deformation and devulcanisation than a direct competitor material. “They displayed better compression set performance and superior resistance to heat and media,” he said.
