breakthrough times for nitrile gloves

Changes in chemical permeation of disposable latex ...- breakthrough times for nitrile gloves ,With exposure to movement, a significant decrease (p ≤ 0.001) in breakthrough time (BT) was observed for the latex (-23%) and nitrile gloves (-31%). With exposure to movement, only the nitrile glove exhibited a significant increase (p ≤ 0.001) in steady-state permeation rate (+47%) and cumulative permeation at 30 min (+111%).EDITION - ResearchBreakthrough time and Rate. Breakthrough times (min.) are the times observed from the start of the test to first detection of the chemical on the other side of the sample (for test methodology, see the outside back cover of this guide).These times represent how long a glove can be expected to provide effective permeation resistance
