BLS did not change the hardness when it developed TUFPADS BLUES. The difference between BLS’s black and blue TUFPADS is an additive in the blue polyurethane itself that. Since TUFPADS BLUES track pads have the same hardness as the original black polyurethane TUFPADS track pads, contractors will receive the same great traction and protection that they always have, but they will receive longer life with the TUFPADS BLUES.
