AMERSORB Separator with +80% Porosity

AMER-SIL S.A has a high performance polymeric separator called AMERSORB, well adapted to both gel and AGM VRLA batteries (application PCT N EP03/5002). Due to its very high pore volume and optimized pore size distribution, the ribbed and corrugated AMERSORB patterns lead to very low acid displacement and electrical resistance, as well as an efficient and controlled oxygen transfer rate.

Contrary to current AGM materials (100% glass or loaded with organic fibres or silica), the flat AMERSORB membrane can avoid drainage and stratification of the liquid electrolyte in AGM batteries, due to the very high capilarity resulting from its specific pore size distribution. The material keeps its initial thickness ( available from 0.6mm to 4.5mm, without glassmat) after filling and during the whole battery life in order to maintain the initial compression of each cell, thus limiting contact loss and softening of the positive active mass.
