SS-IBR is strong blown rubber material to be moulded by injection process. SS-IBR is consisted of high performance synthetic rubber and polyester-based polymer, and then forms hybrid crosslinked network through peroxide curing.

SS-IBR has high mechanical properties and good abrasion resistance along with lower density, which makes it ideal material for running shoes with light weight and casual shoes requiring lower density and good abrasion resistance.

IBR-125 is light weight version of SS-IBR and provides much lighter soles along with good physical properties.
