The manufacturer´s responsible and objetively stated suggestions for product use and application are extremely important to both dealer and end user of a product such as a chemical protective glove. With this in mind, IGARTEX has made up its own chemical resistance chart based in own tests, of other manufacturers and independent laboratories. Whereas in the past resistance meant only resistance to absorption, permeability is today´s primary concern. |

Resistance
to absorption is a key factor in weighting the "handiness" of
a glove for a chemical protective glove that is swollen because
of fluid uptake is unusable. Absorption is easily and accurately
measured by calculating the relative changes in mass, volume or
the linear measurements of the test sample. The surface swelling
percentage results :

Both of the above factors must be considered when judging the resistance of a chemical protective glove material to a specific chemical. As the ideal would be a rate R6, both absorption and permeation resistance, is not applicable in all cases; for short time contact with chemicals (e.g. protection against splashes) a resistance N1 would be a minimum requirement.
