Dimorpholinodiethyl Ether (DMDEE, CAS 6425-39-4) is a high-performance tertiary amine catalyst, distinguished by its exceptional selectivity, low volatility, and strong compatibility with polyurethane (PU) systems—positioning it as a core additive for precision-driven industrial manufacturing. Unlike generic amine catalysts, DMDEE delivers targeted acceleration of urethane cross-linking reactions, minimizing side reactions and ensuring uniform curing without compromising product structural integrity, fully adhering to international quality and environmental standards.

DMDEE’s applications cover a broad spectrum of high-value industries: it is the catalyst of choice for producing rigid and flexible PU foams used in construction insulation and automotive seating, where it boosts foam density consistency and mechanical strength; it acts as a high-efficiency curing accelerator for PU coatings, adhesives, and sealants, shortening production cycles while enhancing bond durability and chemical resistance; additionally, DMDEE serves as a key processing aid in specialty PU elastomers for textile and footwear manufacturing.

Our DMDEE product portfolio includes customized grades (industrial-grade, high-purity grade, and low-odor grade) to match varied application requirements, with strict quality control protocols guaranteeing impurity levels below 0.05% and consistent physical-chemical parameters for stable formulation outcomes. We provide flexible supply solutions, ranging from small-batch sample packs to bulk IBC tote and tank container deliveries, alongside comprehensive compliance documentation (including multilingual MSDS, UN shipping certifications, and REACH registration dossiers). Our dedicated technical team offers one-on-one support—such as PU formulation optimization, catalyst dosage testing, and safe storage guidance—to help you streamline production processes and elevate product competitiveness.
