SPECIFICATION & TYPICAL PROPERTIES

FEATURES & APPLICATIONS

XYlink M-CDEA is an aromatic chain extender. It has good compatibility with TDI-based prepolymer. The reaction of M-CDEA and prepolymer is faster than that of MOCA. XYlink M-CDEA is recommended mainly used for high-performance casting polyurethane elastomers, and can also be used in RIM PUs, microcellular polyurethane elastomers, and spray polyurethane-ureas, etc.

Polyurethane elastomers based on this product have excellent physical properties such as hardness, tear resistance, heat resistance and dynamic mechanical properties (including dynamic heat-generation) than those based on MOCA. The PU elastomers have good cost effective when it mixed with chain extender MOCA and XYlink 740M. XYlink M-CDEA could also be applied as curing agent for epoxy resin and used to produce polyimides. XYlink M-CDEA has lower toxicity with Ames test negative and LD50 (rats) ＞5000mg/kg.
