Hi!! I am looking for 100 % recycled anti skid rubber material approx 5mm thick for a mat.

Our 5mm Pre-Cut Rubber Underlayment is 100% recycled, but is not the best material for a mat. We do offer a wide range of mats that are also recycled. Depending on what you are wanting to do on the mat, determines which one would be appropriate for you. All of our rubber mats are anti-skid and can be found on our Rubber Mats page.
