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.
