WebBreakthrough time - Permeation is the time it takes from an initial contact of the chemical with the material until it is detected on the opposite side of the material (essentially, when it begins to soak through). The greater the breakthrough time, the more protective the material is for that particular chemical. 4 Levels of PPE mavericks motorcycles ltd directorsWebbreakthrough time; permeation rate . Degradation is the change in one or more of the physical properties of a glove caused by contact with a chemical. Degradation typically appears as hardening, stiffening, swelling, shrinking or cracking of the glove.
