Description
XC-8280 is the isocyanate component used with XC-6002C in a polyester-polyurethane footwear system. The system is designed for double-density safety shoes and casual shoes, combining high strength with good abrasion and oil resistance.
Depending on the application, the system provides molded densities ranging from approximately 0.45–0.55 g/cm³ for midsole/insole applications and 0.90–1.10 g/cm³ for outsole applications.
Features
- High-strength footwear PU system
- Good abrasion resistance
- Good oil resistance
- Suitable for safety footwear
- Suitable for casual footwear
- Supports double-density sole construction
- Suitable for outsole and midsole production
