As 2020 sets to close, a piece of good news comes from Daramic which celebrated its 90th year operating as a global leader in lead-acid battery separators.
The US-headquartered firm invented the polyethylene (PE) separator in the 1970s, and has launched a number of new lead-acid battery separator solutions over the past five years.
Dawn Heng, vice president & managing director, global marketing & Northeast Asia at Daramic, told BEST: “As we celebrate our heritage and 90 years in business, we continue the spirit of entrepreneurialism through our company vision “Battery Separators Reinvented”, to deliver upon this promise through a deep understanding of customer needs and a capable, global manufacturing footprint. Daramic is well positioned to maintain industry leadership over the next 90 years.”
In 1930, Dewey & Almy Corporation broke ground on a state-of-art rubber separator plant in the US to mark the beginning of Daramic, LLC. Now, in its 90th year in operation, Daramic materials have been instrumental in supporting battery technologies used to save lives, promote peace, and keep the world in motion.
In 1969, Daramic invented the polyethylene (PE) separator in Owensboro, Kentucky, US. The novel technology set a new standard for separator performance, the core of which is still used today.
Recognising the broad footprint of lead-acid battery manufacturers, Daramic expanded its own footprint in the 1980s when it opened its first European facilities in Germany and France. This was followed by the Thailand plant opening in 2000, and then plants in China and India.
In April, Daramic, was recognised as a 2020 Sally Breidegam Miksiewicz Innovation Award Honorable Mention for its work on partial state of charge (PSoC) operations and modifications to extend life in lead batteries.
Among 13 award finalists, an independent panel of judges recognised Daramic’s separator innovations, which center on novel separator solutions that allow more functional energy storage area and increase charge acceptance. The solutions, provided together or separate, have shown to provide as much as three times longer cycle life than standard SLI separators in partial state of charge testing.
