CAS: 124-09-4
Hexamethylenediamine (HMDA), colourless viscous liquid used in many industrial processes, particularly in plastics and rubbers. Diamine that stands out from the other diamines are high outperform thermal stability and low vapor pressure making is a favourite for high-performance material. It is significant to reinforce resins, plastics and elastomers for applications in end products so as to demand for product durability & resilience.

Applications in the Plastic & Rubber Industry
Hexamethylenediamine is very important in the plastic and rubber industry, an essential precursor to nylon and many other polyamides, nylon is part of our daily lives and we all wear nylon from time to time due to it being the very foundation for many materials that are incredibly durable, yet also lightweight.
