PMDPTA is a low -smelling foam/gel balance catalyst, which can be used in polyether -type polyurethane soft foam, polyurethane hard bubbles and coating adhesives. PMDPTA is especially used in cold mold HR foam. PMDPTA is called five -base di -propyleneramine, which has a wide range of applications in various soft and hard foams. PMDPTA can provide a balanced starting response and gel response, and extend the foam reaction and gel response time. This catalyst can not only be used alone, but also shares with other catalysts and auxiliary agents. PMDPTA can be dissolved in polyether polyol.
It is easily dissolved in most solvents. Foam and gel reaction balance. The advantages are used in soft block foam, which can avoid the cracking and pinhole of the foam, which has excellent raising performance. Improve the processability, tolerance and surface curing performance of hard foam. Improve the higher hole of soft foam plastic.
Property properties: boiling point: 102 ° C / 1mmHg, density: 0,83 g / cm3, refractive index: 1.4450 to 1.4480, flash point: 92 ° C, acidity coefficient (PKA): 9.88 ± 0.28 (Predict). It is mainly used for alkaline melting phenols, and also used for inter -phenylphenols, etc., and is often used as catalysts in esterization and dehydration reactions; dye intermediate
