Frequently Asked Questions

Q: What is the primary function of PMDETA in polyurethane production?

PMDETA acts as a highly reactive catalyst that primarily accelerates the foaming reaction and helps balance the relationship between foaming and gelation.

Q: Can PMDETA be used in both rigid and soft polyurethane foams?

Yes, it is widely used in rigid foams (such as polyisocyanurate plates) and also in polyether polyurethane soft foams and molding foams.

Q: What are the recommended dosages for different foam types?

For rigid foams, the dosage is typically 0-2.0 parts per 100 parts of polyol. For soft foams, 0.1-0.5 phr per 100 phr of polyether is recommended.

Q: How does the PMDETA quaternary ammonium salt differ from the standard catalyst?

The quaternary ammonium salt version is a delayed catalyst. It prolongs the foaming time, making it ideal for complex shapes and box-type foaming processes.

Q: Does PMDETA work well with other catalysts?

Yes, while it can be used alone, it is often shared with other catalysts like DMCHA to achieve a specific balance of reactivity and foam structure.

Q: How does PMDETA impact the final physical properties of the foam?

It enhances the overall toughness and bearing capacity of the foam while improving the internal structure and molding quality.
