Abstract
An absorption mat 1 receives organic hydrocarbons in liquid, paste-like or solid form, for example, oil, fats, fuels and solvents. The absorption mat includes a plate-like molded body 2 made of rubber granulate 3 or rubber shavings 3 bonded to each other to define a plate-like body. A base layer 6 resistant to the hydrocarbons is joined by vulcanization to the plate-like molded body 2. The base layer 6 is a composite base barrier layer including first and second layers (10, 12) made of hydrocarbon resistant material and a mesh-like support layer 14 is sandwiched and trapped between the first and second layers (10, 12) for preventing unwanted stretching of the mat during manufacture and when handling before placement on the ground or floor area and when in use.
