  • Separators
  • Gauntlets

AMER-SIL separators are made with a unique extrusion process which leads to outstanding product characteristics.
The materials used – stabilized PVC polymer and silica – are very pure and chemically stable. Depending on pattern and formulation, the volume porosity range goes from 68% to more than 90%!
The very high porosity and extremely low electrical resistance of the separator help our customers to deliver more Ampere hours at the same cost.
Our separators are available in two versions: ribbed or corrugated, with tailored thicknesses from less than 1mm up to 5mm. They are suitable for any industrial traction or stationary battery application.
Its particular characteristics – very high porosity, together with right pore size distribution – make AMER-SIL separators the best option for gel batteries.

Ribbed Separators

Higher porosity : The higher porosity of the AMER-SIL separators is due to the high silica content and open structure of this material. Volume porosity ranges from 65% to 78%

Lower electrical resistance : This characteristic is also influenced by the high porosity open material structure. It is among the lowest of industrial separators. Values of electrical resistance are highly dependent on overall thickness, back web thickness and profile.

Chemical purity : The material composition is limited to two basic materials, precipitated silica and PVC-polymer. There are no additives or mineral oils or resins. The grey color is achieved by adding minute amounts of carbon black.

Chemical and physical stability : This comes from the chemical components and the unique manufacturing process. This type of separator does not oxidize and has excellent aging characteristics.

Versatility : Wide range of thickness and dimensions are possible as well as a variety of profiles. All profiles can also be offered with glass mat lamination.

Corrugated Separators

Highest Porosity : The same high porosity Amer-Sil microporous material is further slightly stretched giving the highest Porosity. Volume porosity ranges from 69% to 78%.

Lowest Electrical Resistance : The only electrical resistance to electronic flow is posed by the deformed flat microporous membrane. The value of the corrugated separator electrical resistance depends on the thickness of the starting flat membrane.

Chemical Purity : The material composition is limited to two basic materials, precipitated silica and PVC-polymer. There are no additives or mineral oils or resins. The grey color is achieved by adding minute amounts of carbon black.

Chemical and Physical Stability : Chemical stability is assured by components and the unique manufacturing process. Thickness loss is limited to less then 5% up to 70%. This separator does not oxidize and has excellent aging characteristics.

Compressibility : The corrugated separator has the unique ability to yield under compression and keep that compression. Typical compression is 5% at 20 kPa.

Lowest Electrolyte Displacement : This characteristic reflects the lower material used to achieve a given thickness. Typically acid displacement is 40% to 50% lower.

AMER-SIL & KETEX : Two Industrial leaders joined hands to assure the best solutions.
Our customers profit today from a consolidated experience of 60 years in gauntlets design and in production’s most advanced processes.

AMER-SIL KETEX woven & non-woven gauntlets are available in many diameters, fabrics and shapes making our portfolio the broadest in the market. On request, the gauntlets can be supplied with edge protection. The edge protection is a very efficient and proven barrier against short-circuits due to lateral mossing. Today, we offer the broadest portfolio of woven and non-woven fabrics to the market, we profit also of the largest production network worldwide.

Amer-Sil gauntlets are for use in any industrial application: in traction and stationary batteries, in flooded as well as in VRLA batteries.
