Penetration refers to the state in which liquid chemicals pass through the micropores and seams on the material.
Permeation refers to the state in which hazardous chemicals are small molecules that penetrate through barrier substances to diffuse.
The penetration test is very suitable as a way to confirm whether the fabric can block specific particles. The variables that affect the particle penetration state include the size of the particle molecules and the pore size in the fabric structure. The larger the pore size of the fabric structure itself, the more likely the particles will penetrate the fabric.
DEREKDUCK has successfully conducted a number of chemical substance penetration tests for ULTITEC1000L, 1000, 1000FR, 2000, 2000B, and 3000T. In contrast, the Permeation test is more suitable for testing harmful liquids and gases. DEREKDUCK has successfully conducted a number of chemical substance penetration tests on ULTITEC 4000 and 5000 fabrics.
