Outstanding stability

The raw materials used have a very high intrinsic resistance to oxidation. Therefore, contrary to polyolefin based products (such as PE), no oil must be added to protect the polymer from oxidation and black scum issues are avoided.

The use of stabilizers gives high thermal stability to Amer-Sil separators (stabilizers proven in other extreme applications, such as cable industry).
As a result, the separator can be used in any kind of battery and application: motive power and stationary, flooded and gel. More than forty years of use in even the longest-life applications and in all types of environment prove this point. Articles have been published by battery manufacturers, analysing the life of very-long life batteries (>20 years). Several used Amer-Sil separators.
