KO-8 is a 100% cork used for die ejection applications. Since this material is not a rubber product there is no "shore scale" reading. The sheet size is 36" x 36" and comes in many different heights:
1/4", 5/16", 3/8", 1/2"
and can be kiss-cut or strip-cut to any size to suit your needs. We can also custom cut pads and sheets i.e. 18" x 36" or 9" x 18"
