AMER-SIL Ribbed Separators

The AMER-SIL standard calendered ribbed separators are made by physical (non-thermal) bonding of a polymer and precipitated silica.
This material is very pure and chemically stable.

The internal structure is very porous, tortuous and hydrophilic. The product can be supplied in a "standard" or "high porosity" (HP) grade.

• AMER-SIL Standard Porosity:
  Finds its application mostly in motive power (traction) battery application. Also in gelled VRLA and flooded stationary batteries.

• AMER-SIL HP (High Porosity):
  Is used in cells where lower electrical resistance and higher porosity are required, these include: high energy density traction batteries, some types of gelled VRLA batteries, heavy duty starter batteries and traction monobloc batteries such as golf cart and electric vehicle batteries.

• AMER-SIL separators can all be offered with Glassmat laminated on one side.
