XC-6230T is the isocyanate component used with XC-2088B in a polyester-polyurethane footwear system. The system is designed for middle sole and insole applications, with a focus on low-density foam, good handle, and dimensional stability.

When combined according to the recommended processing parameters, the system achieves a molded density of approximately 0.38–0.40 g/cm³.
