Overview:

Pentamethyldiethylenetriamine is a highly active catalyst for polyurethane reactions, which mainly catalyzes the foaming reaction, but is also used to balance the overall foaming and gelation reactions. It is widely used in various polyurethane rigid foams, including polyisocyanurate sheet rigid foams. Pentamethyldiethylenetriamine is a chemical substance with the molecular formula C9H23N3. It is a highly efficient catalyst for polyurethane soft foams and is used in the formulation of soft foams, and also as a co-catalyst for hard foams to improve the fluidity of PU foams for large capacity refrigerators.

Characteristics and Uses:

Pentamethyldiethylenetriamine is a highly active catalyst for polyurethane reaction, it catalyzes the foaming reaction mainly, and is also used to balance the overall foaming and gel reaction. It is widely used in various polyurethane rigid foams, including polyisocyanurate sheet rigid foams. Due to its strong foaming effect, it can improve the foam fluidity, so it improves the product production process and increases the production volume, and it is often used together with DMCHA and so on. Pentamethyldiethylenetriamine is used alone as a catalyst for polyurethane foam formulations or in combination with other catalysts. When used alone as a hard foam catalyst, the dosage range is 1.0-2.0 parts per 100 parts of polyol.

In addition to being used in rigid foam formulations, pentamethyldiethylenetriamine can also be used in the production of polyether-based polyurethane flexible block and molded foams. For example, 70% of pentamethyldiethylenetriamine is mainly used in the formulation of flexible foam products, the catalyst is active, the foaming speed is fast, and the products have high toughness as well as high load-bearing properties. In the soft foam every 100 parts of polyether the catalyst 0.1-0.5 parts can get better results. It can also be used as auxiliary catalyst for hard foam.

Pentamethyldiethylenetriamine quaternary ammonium salt is a delayed catalyst for soft foam, used to prolong the foam whitening time, suitable for complex shaped foam products and box-type foaming process, improve the structure of the bubble holes, and improve the quality of molding. Its own dosage range is quite wide, and the change of dosage has no obvious effect on the emulsion time; however, the increase of dosage can shorten the foam rising time, and can shorten the curing time.
