High Wet Strength

Applications using filter paper in a system under pressure or vacuum require the use of high wet strength grades;

FILTECH Qualitative High Wet Strength Grades of filter paper contain a small amount of chemically stable, insoluble binding resin which strengthens the natural fibre to fibre bonds under wet conditions.

Grades containing wood fibre or resins are not recommended for use in quantitative ashing techniques or in Kjedlahl estimations.
