The WSD02 Wet Stretch Dynamics Analyzer is a test device, which measures the wet expansion of paper under one-sided contact with water or other test liquids.
The devices measures the dynamic of the of the change in dimension (stretching/shrinking) of paper, board and other materials as soon as it comes to an one-sided contact with the test liquid. Especially interesting is the measurement of décor paper under one-sided liquid contact (e.g. water, melamine resin and others). In addition, the change of the dimension of gypsum board, coating base paper, newsprint or offset printing papers can be measured under one-sided contact with water or inkjet ink.
The WSD02 replaces the classic methods to measure wet stretch behavior, which function under two-sided contact of the test liquid.
