Product Introduction
1. Product Overview of DBU Polyurethane Catalyst
DBU, full chemical name 1,8-Diazabicyclo[5.4.0]undec-7-ene, CAS No.6674-22-2, is a high-activity bicyclic amidine tertiary amine catalyst widely applied in polyurethane production lines. As a powerful gel catalyst for PU systems, DBU delivers excellent catalytic performance for aliphatic & alicyclic isocyanate formulas, accelerating polyol-isocyanate crosslinking reactions at variable temperatures and optimizing foaming, curing & demolding efficiency of polyurethane materials.
Our company is a professional China factory integrating DBU R&D, mass production and global export. Unlike trading companies without production capacity, we control the whole manufacturing chain from raw material synthesis to finished product inspection, guaranteeing consistent DBU performance for global polyurethane manufacturers.
2. Key Technical Specifications of Our Factory DBU Catalyst
We strictly execute unified production standards to ensure stable physical & chemical indicators across all batches, eliminating quality fluctuation issues that trouble many imported or middleman-supplied DBU products.

3. Main Application Fields of DBU Polyurethane Catalyst
Our high-stability DBU catalyst fits nearly all mainstream polyurethane manufacturing scenarios, covering industrial foams, elastomers and coating materials:
- Microporous polyurethane elastomers, self-skinning foam & integral skin foam
- Rigid PU foam, insulation foam and aliphatic isocyanate PU coatings
- PU shoe sole formulations, automotive PU interior parts and electronic potting glue
- Epoxy resin curing accelerators, pharmaceutical intermediate deacidification agent
- Synthetic leather PU slurry, polyurethane adhesive & sealant systems
DBU features temperature-sensitive catalytic activity: its gel acceleration effect multiplies significantly under heating conditions, greatly shortening product molding cycles and boosting factory production throughput for PU manufacturers.
4. Four Core Advantages of Our China Factory DBU Catalyst
4.1 Direct China Factory Supply, Complete Production Line
We are a local Chinese chemical manufacturer with independent DBU synthesis workshops, automated reaction equipment and dedicated purification workshops, no intermediate distributors. All DBU products are produced, tested and shipped directly from our factory to overseas clients. We support flexible bulk order production scheduling to match customers’ annual procurement plans, with stable monthly output to avoid stock shortage risks.
4.2 Ultra-Stable Batch Quality, Strict Full-Process Inspection
Stable quality is the core competitive edge of our DBU polyurethane catalyst. We set up a full-chain quality control system covering raw material incoming inspection, mid-process sampling monitoring and finished product double testing. Every batch of DBU undergoes repeated purity, viscosity and catalytic activity tests in our internal laboratory before delivery.
We eliminate unstable low-purity recycled raw materials adopted by small workshops, so our clients will not face problems including inconsistent curing speed, defective PU finished products and formula failure caused by fluctuating DBU quality. Long-term cooperative PU manufacturers worldwide recognize our stable batch consistency.
4.3 Factory Direct Competitive Price, No Markup
By cutting all middle trading links and realizing large-scale automated production, we offer DBU at transparent factory ex-factory price without extra markup fees. Compared with overseas local chemical suppliers and import traders, our unit cost has obvious advantages under the same purity standard. For long-term bulk order clients, we provide tiered preferential pricing to lower your overall raw material procurement cost steadily.
4.4 Long-Term R&D Cooperation with Chinese Universities & Research Institutes
To continuously upgrade DBU synthesis technology and quality detection standards, our factory maintains long-term joint research cooperation with multiple domestic universities and professional chemical research institutes in China.
Our joint laboratory team carries out two major research directions all year round:
- Optimize DBU green synthesis production processes: reduce impurity generation during synthesis, raise product purity and lower comprehensive production loss, further stabilize catalytic performance in complex PU formulas.
- Develop precise, fast detection methods for DBU catalyst indicators: build exclusive testing standards for catalytic activity, moisture content and impurity residues, so we can provide more accurate, targeted test data for customers’ formula adjustment.
The university joint R&D platform also supports customized DBU modified catalyst development for clients with special polyurethane formulation requirements, solving unique production pain points of different PU manufacturers.

7. FAQ
Q1: Are you a DBU trading company or real China manufacturer?
A: We are a genuine Chinese chemical factory with independent DBU synthesis production workshops, R&D labs and inspection centers. All DBU polyurethane catalysts are self-produced, not purchased from third-party suppliers for resale. We welcome factory field visits for overseas clients.
Q2: Can your DBU maintain stable catalytic performance for long-term mass production?
A: Yes. Supported by joint research with Chinese universities, our unified synthesis & testing standards guarantee nearly identical indicators for every batch of DBU, effectively avoiding formula instability caused by quality fluctuation. We can provide historical batch COA records for reference.
Q3: Is your DBU price more competitive than other suppliers?
A: As direct factory without middlemen, our large-scale production cuts extra circulation costs, so we offer more favorable unit prices under equivalent purity grade. We supply tiered discounts for annual bulk purchasing contracts.
Q4: Can you provide technical support for polyurethane formula adjustment?
A: Absolutely. Our internal technical team cooperates with university chemical research institutes to offer free technical guidance on DBU dosage matching, PU curing speed optimization and abnormal production troubleshooting for all clients.
Q5: Do you support customized purity and modified DBU catalysts?
A: Yes. Our university joint R&D lab can customize DBU products with specified purity, or develop modified DBU composite catalysts to match special aliphatic PU, microcellular elastomer and coating formulas as per customer samples.
