WEINHEIM, Germany—A 2024 report by Unesco states that 2.2 billion people worldwide live without clean drinking water, and 3.5 billion lack access to safe water sanitation. In the face of modern climate change, the new Freudenberg Sealing Technologies O-ring compound will be exceptionally important.
The German firm is working to keep drinking water safe and sanitary across the globe with its new 70 EPDM 335DW compound for O-rings, introduced by the company March 19.
Klaus Schmieder, segment manager at Freudenberg Sealing Technologies, said that the new O-ring compound is designed for the most stringent drinking water standards. He called the development of the compound "a significant achievement" for the Freudenberg team.
"We have rigorously tested this material to ensure it meets the highest standards for drinking water applications," Schmeider said. "Our goal is to provide reliable and safe solutions that contribute to the well-being of communities worldwide."
The compound boasts strong heat resistant properties up to 150ºC (302ºF) according to Freudenberg officials, as well as high levels of effectiveness in cold conditions with temperatures as low as -50ºC (-58ºF).
"The compound demonstrates good aging resistance and is suitable for drinking and process water, hot water, superheated steam, silicone oils," Schmeider said. "These characteristics make it an ideal choice for clean drinking water applications where durability and safety are paramount."
The new product ensures protection for the health of the drinker and the wider environment, according to Freudenberg officials. It can be used in several drinking water applications around the world. The compound material is tested up to the highest safety standards possible, including the European Positive List and KTW-BWGL guidelines for O-rings smaller than 63mm.
"Obtaining these certifications is essential for ensuring the safety and reliability of our products," Schmieder said. "The rigorous testing and compliance with international standards demonstrate our commitment to providing high-quality materials that protect public health and meet the demands of modern drinking water systems."
Full ACS certification for Freudenberg's material in larger O-rings is still in the testing phase, Freudenberg said.
