When Does PEEK Filter Fabric Pay for Itself?

PEEK is expensive and in most applications unnecessary. The honest cost case is cost per operating hour including downtime – and the four conditions under which it genuinely wins.

Trockene vs. feuchte Wärme: Warum Filtergewebe unter ihrer Nenntemperatur versagen

Temperaturangaben auf Datenblättern sind Trockenwerte. In heißem Wasser, Dampf oder heißer Lauge übernimmt die Hydrolyse deutlich unterhalb dieser Grenze – und das Schadensbild sieht völlig anders aus.

Dry Heat vs. Wet Heat: Why Filter Fabrics Fail Below Their Rated Temperature

Datasheet temperature figures are dry-heat values. In hot water, steam or a hot caustic wash, hydrolysis takes over well below that limit – and the failure pattern looks completely different.
