Chemical Resistance Data Sheet
This data sheet incorporates three types of information:
Breakthrough Time (BT)
BT is the elapsed time between the initial application of a test chemical to the outside surface of a protective glove material and its
subsequent presence on the other side of the material, and the time at which the permeation rate reaches 0.1mg/m2/sec in EN374.
Numbers in the table shows the permeation resistance levels based on time and EN374 of BT.
Permeation resistance level is as follows.
Chemical A :Methanol B :Acetone C :Acetonitric D :Dichloromethane E :Carbon disulfide F :Toluene
Chemical G :Diethylamine H :THF I :Ethyl acetate J :n-Heptane K :40％ Sodium hydroxide L :96％ Sulfuric acid
hemical M:65% Nitric Acid N :99% Acetic Acid O :25% Ammonia P :30% Hydrogen peroxide Q :40% Hydrofluoric acid R :37% Formaldehyde

deleterious change in one or more properties of a protective glove material due to contact with a chemical. These changes
include flaking, swelling, disintegration, embrittlement, discolouration, dimensions, appearance, hardening,
The following data is meant as a reference showing our product’s reaction to various chemicals. The data is not meant as proof
of the product’s performance ability. In addition, this data does not indicate the product impermeability.
- Performance Grade
- E Excellent
- G Good
- B Bad
- D Do not use
Protective gloves selection must be based on the user’s assessment of the workplace hazards. Glove materials do not provide
unlimited protection against all chemicals. It is the users’ responsibility to determine before use that the glove will resist perme-
ation and degradation by the chemicals in the environment of intended use.
