Abstract (en)
[origin: WO2005053818A1] The invention relates to a porous, permeable, inherently stable filter element, which (a) is suitable for use at a permanent temperature ranging between 50 and 200 DEG C and/or (b) has an excellent acid resistance. Said filter element is characterised in that it comprises a main constituent containing particles of a first material, said particles being held together by an adhesive. Prior to the processing of the adhesive with the main constituent, which consists of heating the mixture to a bonding temperature, the adhesive takes the form of a granular plastic starting material, which liquefies at the bonding temperature and either cures to form a duroplastic or solidifies to form a thermoplastic.
