POROMAT ® 2248 consists of a glass mat compressed with a small amount of epoxy resin to a rigid but porous laminate.  POROMAT ® 2248 contains only a small amount of binder and is therefore porous and absorbent.

At temperatures > 60 °C or in contact with impregnating resins the laminate swells to about 150 % of the initial thickness and fills up all existing free space.  The properties of the final laminate depend on the impregnating resin and the amount of swelling.

Applications

POROMAT ® 2248 can be used in VPI systems as interlayer, spacer or filling material in different parts of electrical windings.
POROMAT ® 2248 was developed especially for impregnating resins containing accelerator or catalyst.
