Technical Details & Test Data
- Improving Performance in Cast Polyurethane Systems in Mdi-fbdo Formulations
SABIC’s NORYL™ AP2001G polyol in MDI-BDO formulations can provide enhancements in stiffness, toughness and hardness. Additional benefits to these formulations include an increase in cohesive strength and demonstrated retention of physical properties at elevated temperatures. These benefits were observed when compared to standard MDI-BDO and TDI-MOCA formulations. Improvements in chemical and environmental resistance can also be achieved with the inclusion of NORYL AP2001G polyol.
Relative Performance of Ptmeg-based Cast PU Formulations
Adding 5.6% of NORYL AP2001G polyol to a standard MDI-BDO Cast PU formulation yielded significantly improved mechanical properties (+8% elongation; +26% tensile strength; +30% toughness and +1.4 shore D points of hardness) at room temperature (20° C).
- NORYL™ AP2001G Polyol Solution Performance Data
The potential benefits of the formulation containing NORYL AP2001G polyol versus standard MDI-BDO include:
- Increased hardness
- Higher modulus and tensile strength
- Improved elongation and toughness at room temperature
