That is very true Rob. Mat suppliers usually don’t publish chemical resistance charts. However, chemical resistance does track between the major rubber types. So if the job requires nitrile gloves, then nitrile mats would be a good choice without doing a lot of research.


Since we’re talking about chemical resistance of industrial rubbers, I’d like to share a link to my favorite database. It is the General Chemical Resistance Guide from The Los Angeles Rubber Group hosted in Dupont’s website. This free database gives you the resistance rating for all the major rubber types based on volume swell test data for various chemicals at different concentrations and temperatures. Their test method page also includes a handy cheat-sheet per rubber type.


One last thought to share… consider the clean-up & decontamination you’d have to do if a spill occurs. This may help you choose between standard mats and modular mat-tiles.


Thank you,


Yaritza Brinker

Most of the mats I’ve seen are listed as “oil resistant” but do not list specific chemicals the way you would see with a glove selection chart.


My company is a NoTrax distributor. This one says it is "Resilient natural rubber compound withstands many common industrial cutting oils and chemicals”:  while this one says it is “highly resistant to grease, oils and animal & vegetable fats”:   There are many more on their web site.  If you would like some pricing, custom sizes, etc. simply contact me off list.


Yartiza’s comment about lining up mats works if you have a modular mat design in which the bevels can be removed and the mats connected. These are called mat tiles; see  Notice they have some nice nitrile rubber ones; nitrile provides highest level of resistance to chemicals, oils and greases that Notrax apparently offers:  as well as  The beveled edges are sold separately.

Is there a certain type of material recommended for an anti-fatigue floor mat to be used in a "general chemistry" type of storeroom at a college? I was concerned about chemical interactions with concentrated acids, bases, hydrogen peroxide, or acetone if a spill would occur. Also, are these considered a tripping hazard?


Thank you for any information,
