Does PERMA-FLEX eventually break-down to a dirty, black soot?
A product that is often confused with PERMA-FLEX is sometimes referred to as “tire shreds” or “tire buffings”, which is the bi-product of retreaded tires. These shreds are long and thin and, as such, are not very durable. The sand typically used with most rubber products is too abrasive with the shreds and eventually “sands them down” into a fine, black dust. PERMA-FLEX’s particle shape is durable and will not pulverize. What you see on day 1 will be the same 50 years from now!
