At AMER-SIL we believe we can make a significant contribution to ensuring a green future for generations to come through energy storage applications, which actually represent one of the biggest challenges facing humankind. Being an independent company gives us the freedom to set ambitious medium- and long-term goals. The competitive environment which now prevails in the battery sector makes it even more crucial to be able to adapt and change quickly. With its high-powered R&D and its flexible production capabilities, AMER-SIL can offer you tailor-made solutions to meet your challenges.


AMER-SIL has been designing and producing high-performance micro-porous polymer/silica separators for all types of industrial lead acid batteries for 50 years now, and we are the market leader in various segments.

In 1989, AMER-SIL introduced non-woven gauntlets for tubular positive plates and the market has since adopted this advanced technology. The joint venture which came into being between AMER-SIL and the Indian gauntlet producer KETEX in 2015 established AMER-SIL as the global leader for both non-woven and woven gauntlets.

In 2018/2019, the company also launched microporous separators for redox flow batteries. Today, Amer-Sil is the only global supplier offering a combined portfolio of separators and gauntlets for industrial batteries.

GUY JOZEF DAUWE JUNE 1, 1968 – JULY 25, 2019

On July 25, 2019, we had to announce with big sadness the death of Guy Dauwe, our dynamic and much liked managing director of Amer-Sil. He died of cancer in a Luxembourg hospital with only 51 years.

Till today he is deeply missed at many levels. His approach to everyone could probably be called paternalist, he was keen to get the best out of people for their benefit as much as for the company. He was a great guy to work with.
Intellectually he was brilliant, he stood head and shoulders above the rest. He was a very high-level person — a man full of ideas. And good ideas too.

Guy joined Amer-Sil in April 2005 as an executive vice president in charge of sales and marketing. He was the managing director at Amer-Sil since July 2006. One of his early initiatives was to move the firm into lean management and continue investment in R&D. In 2009 Guy spearheaded the setting up of a manufacturing plant in Shanghai. In December 2014, he led the successful management buyout of Amer-Sil from the US parent The Moore Company.

At the time of his death Guy, as a true entrepreneur and long-term oriented individual, was preparing to set up a new company to further develop the business.

Guy will forever stay in the heart of Amer-Sil and we look back with gratitude on all achievements he accomplished during his time in the company.
