Chem-Ply N-540

Ultra-high performance chemical protection

  • Broad chemical resistance (acids, aliphatic solvents, solvent mixtures), increased by the thickness of the material
  • Good grip, due to embossed texture
  • Easy to pull on and off, due to chlorinated interior

Specific features

The two neoprene layers superimposed increase the mechanical and chemical resistance. The glove red inner layer ensures that any wear is clearly visible, providing optimal safety for the user.

Operating instructions

Instructions for use

  • It is recommended to check that the gloves are suitable for the intended use, because the conditions of use at workplace may differ from the "CE"-type tests.
  • It is not recommended for persons sensitized to dithiocarbamates to use these gloves.
  • Put the gloves on dry, clean hands.
  • Do not use the gloves in contact with a chemical for a duration in excess of the measured breakthrough time. Refer to the website or contact the Technical Customer Service - MAPA PROFESSIONNEL ( in order to know this breakthrough time. Use 2 pairs alternatively when in long duration contact with a solvent.
  • Turn the cuff end down in order to prevent a hazardous chemical from dripping onto the arm.

Storage conditions

Store the gloves in their original packaging at a temperature not below 5°C.

Laundering conditions

Before taking off the gloves, clean them as appropriate :

  • in use with paints, pigments and inks : wipe with a clean cloth dampened with a suitable solvent, and rub over with a dry cloth
  • in use with a solvent (diluents, etc...) : rub over with a dry cloth
  • in use with acids or alkalies : thoroughly rinse the gloves under running water, and rub over with a dry cloth

Caution : using the gloves or submitting them to cleaning or laundering process which are not specifically recommended can alter their performance levels.

Drying conditions

Ensure the inside of the gloves is dry before putting them on again.

*not normalized result

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.

Used for high chemical exposure or chemical immersion, limited to BTT based on a working day.

Used for repeated chemical contact, limited to total chemical exposure i.e. : accumulative BTT 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, such as concentration and temperature, glove thickness and glove reuse, may also affect performance. Other glove requirements, such as length, dexterity, cut, abrasion, puncture and snag resistance, or glove grip also need to be considered in making your final selection.
