Technical Data Sheet

DC PC-5

Description

DC PC-5 is a tertiary amine which strongly promotes the urea reaction in a variety of rigid and flexible polyurethane foam applications.

Applications

DC PC-5 is very effective in MDI based pour-in-place polyurethane systems such as rigid appliance. It is also used in conjunction with a trimer catalyst in PIR laminate boardstock formulations.

DC PC-5 can also be used in TDI, TDI/MDI and MDI high resiliency (HR) flexible molded foams as well as integral skin and microcellular systems.

Storage Information

Qiguang Group recommends that our catalysts be stored in a dry and cool area under appropriate ventilation conditions. Each container should be closed tightly to avoid contamination with moisture or other negative influences that could change the products' performance in the end use. The optimum storage temperature is between 10 °C and 30° C. Lower and higher storage temperatures are not preferable and should be avoided.

System of law
Pentamethyldiethylenetriamine is generally obtained by N-methylation of diethylenetriamine as a raw material, and the methylation method includes a formic acid/formaldehyde method, a formaldehyde hydrogenation method, and the like.

特性和用途
五甲基二乙烯三胺是一种高反应性、强发泡性的聚氨酯催化剂，也可用于平衡整体发泡和胶凝反应。它广泛用于各种聚氨酯硬质泡沫，包括聚异氰尿酸片状硬质 泡沫，还可以提高泡沫流动性，从而改进产品生产工艺，提高产品质量。五甲基二乙烯三胺也可单独用作聚氨酯泡沫配方的催化剂，或与其他催化剂（如DNS HA）一起使用。当单独用作硬质泡沫催化剂时，其量在每1质量份多元醇0.2至0.100质量份的范围内。除了用于硬质泡沫配方外，五甲基二乙烯三胺 还可用于生产聚苯乙烯泡罩泡沫和模塑泡沫。
