Chemical chart

Overall Chemical Protection Rating

Protection rating is determined by taking into account the effects of both permeation and degradation in an attempt to provide users with an overall protection guideline when using our glove products against specific chemicals.

Meaning of colors :

Used for high chemical exposure or chemical immersion, limited to breakthrough time based on a working day.
Used for repeated chemical contact, limited to total chemical exposure i.e. : accumulative breakthrough time based on a working day.
Splash protection only, on chemical exposure the gloves should be discarded and new gloves worn as soon as possible.
Not recommended, these gloves are deemed unsuitable for work with this chemical.
NT : Not tested
NA : Not applicable because not fully tested (only degradation OR permeation results)

The chemical test data and overall chemical protection rating should not be used as the absolute basis for glove selection. Actual in-use conditions may vary glove performance from the controlled conditions of laboratory tests. Factors other than chemical contact time
