Product Introduction
Nanjing Chem Co.,Ltd. is a China-based supplier and exporter of DMDEE polyurethane catalyst product, chemical products and related products. DMDEE (CAS: 6425-39-4 ) is mainly used as a polyurethane catalyst in China,Pakistan,US,India,Brazil,etc.
1. Introduction
DMDEE, also known as Dimorpholinodiethylether, is a balanced tertiary amine catalyst specially developed for polyurethane foam systems. As a core blowing & gelation dual-purpose PU catalyst, it delivers moderate catalytic activity without causing excessive early foaming or rapid surface curing defects.
Our factory covers 100 acres with 150 staff including 30 professional R&D engineers. We maintain long-term technical cooperation with multiple universities and scientific research institutions, jointly conducting in-depth research on polyurethane materials, PU raw material synthesis, green production process optimization of polyurethane catalysts, product quality upgrading, and waste water & solid waste harmless treatment technology. R&D achievements are fully applied to our DMDEE production line, realizing low VOC, low odor, high purity and eco-friendly manufacturing standards that meet global chemical export compliance requirements.
Different from ordinary industrial-grade DMDEE, our product undergoes continuous distillation and impurity removal procedures under optimized green processes, effectively reducing residual amine odor and volatile organic compounds. It is widely recognized by PU manufacturers across Southeast Asia, Europe, the Middle East and North America as a reliable catalyst for various polyurethane foaming formulas.

5. FAQ
Q1: What advantages does your DMDEE have compared with other manufacturers’ products?
A: We cooperate with multiple universities and professional research institutes to optimize the whole green production flow of polyurethane catalysts. Our DMDEE adopts advanced continuous purification technology to control free morpholine and volatile content at ultra-low levels. Meanwhile, our R&D team continuously upgrades wastewater and solid waste treatment systems in the workshop, balancing product performance and environmental compliance. Stable batch consistency is guaranteed for long-term mass production cooperation.
Q2: Is DMDEE suitable for both polyether and polyester PU systems?
A: Yes. DMDEE shows good compatibility and stable catalytic effect in both polyether polyol and polyester polyol formulas, applicable to most flexible, rigid and semi-rigid polyurethane foam production.
Q3: Can you provide customized low-odor DMDEE grades?
A: Absolutely. Our joint university laboratory can adjust the distillation and refining process to produce ultra-low odor DMDEE according to customers’ special requirements for high-end PU foam products. We support sample testing before bulk order.
Q4: What export certifications can you provide for DMDEE?
A: We supply full sets of export documents including COA, SDS, REACH registration data, packing list, commercial invoice and customs declaration materials. Our factory passes regular third-party factory audits for global chemical B2B clients.
Q5: What is the recommended dosage of DMDEE in polyurethane foam formulas?
A: Typical dosage ranges from 0.3–1.5 parts per hundred polyol (PHP), adjusted based on foam density, production temperature and foaming equipment. Our technical team can provide free formula guidance based on your production conditions.
Q6: How do you handle technical support after purchase?
A: Supported by our university cooperation R&D team, we provide one-stop technical services including formula optimization, catalyst dosage adjustment, and on-site production problem solving for polyurethane raw material and foaming processes. We also share green process improvement schemes to help clients reduce production waste and cost.
Q7: What is your delivery cycle for bulk DMDEE orders?
A: Conventional specifications have sufficient stock, delivery within 7–10 working days after deposit confirmation. Custom modified grades take 15–20 days for production, with stable supply capacity for long-term annual framework orders.
