Tri-Duro is a welding mat with an SBR rubber surface that repels sparks and hot metal shards. This surface material has a melt point of over 500 degrees Fahrenheit. The nitrile-enhanced sponge base absorbs repeated compression and bounces back to its original form better than any PVC sponge alternative.
