Exceptional Catalytic Activity
The sterically unhindered nitrogen atoms in PMDETA provide strong promotion of both gelling and blowing reactions, enabling reduced catalyst loading levels and faster demolding times, boosting production throughput.
Improved Foam Flowability
Especially in complex molds for rigid foam applications, PMDETA ensures the liquid foam mixture maintains low viscosity for longer, allowing for complete mold filling and preventing voids or density gradients.
Reduced Foam Friability
It helps in creating a more uniform cell structure in rigid foams, significantly reducing surface friability. This results in more durable and robust end-products, particularly important for construction panels and spray foam insulation.
Balanced Reaction Profile
While highly active, PMDETA provides a good balance between the cream, gel, and tack-free times. This balanced profile is crucial for achieving optimal foam properties and processing windows.

Real-World Success: Application Case Studies (Experience & Trust)
Case Study 1: Enhancing Production Speed for a Leading Appliance Manufacturer
Client: A major European refrigerator and freezer manufacturer.
Challenge: The client was facing a production bottleneck in their cabinet foaming line. Their existing catalyst system required a long demold time, limiting the line speed and overall output.
Solution: Our technical team worked with the client to replace a portion of their slower gelling catalyst with Hegrecat PMDETA. We helped them titrate the optimal level to balance flowability with cure speed.
Result: By incorporating Hegrecat PMDETA (Pentamethyldiethylenetriamine) CAS: 3030-47-5, the client successfully reduced their demold time by 18%. This directly translated to a 15% increase in production line throughput without any capital investment in new machinery. They also reported improved foam density distribution in complex cabinet corners.
Case Study 2: Improving Surface Quality in Spray Foam Insulation (SPF)
Client: A North American supplier of residential and commercial spray foam insulation systems.
Challenge: The client's fast-reacting SPF system suffered from surface "popcorn" and friability, especially in colder application temperatures, leading to customer complaints and costly callbacks.
Solution: We recommended a catalyst package that included Hegrecat PMDETA as the primary gelling catalyst. Its ability to maintain liquidity slightly longer at the start of the reaction allowed for better surface wetting and leveling before the foam rapidly cured.
Result: The new formulation exhibited a smoother, more durable surface finish with a significant reduction in friability. The client saw a 40% decrease in quality-related complaints and was able to market their product as a premium, "smooth-finish" SPF system, enhancing their brand reputation.
Frequently Asked Questions (FAQ)
1. What is the primary role of Hegrecat PMDETA in polyurethane foam?
Hegrecat PMDETA is a highly active tertiary amine catalyst. Its primary role is to accelerate the two main reactions in PU foam formation: the gelling reaction (isocyanate + polyol → urethane) and the blowing reaction (isocyanate + water → urea + CO₂). It is a particularly strong gelling catalyst, which means it rapidly builds the polymer network, leading to faster cure and demold times.
2. How does the molecular structure of PMDETA affect its catalytic activity?
PMDETA's structure (N,N,N',N'',N''-Pentamethyldiethylenetriamine) features three nitrogen atoms. These nitrogen atoms have lone pairs of electrons that catalyze the reactions. Crucially, the methyl groups attached to the nitrogens are small, resulting in low "steric hindrance." This makes the catalytic sites highly accessible to the reacting molecules (isocyanates and polyols), leading to its exceptionally high activity compared to catalysts with bulkier groups.
3. What are the recommended storage conditions for Hegrecat PMDETA?
To ensure its 24-month shelf life, Hegrecat PMDETA should be stored in its original, unopened container111 in a cool, dry, and well-ventilated area away from direct sunlight and moisture. The container111s should be tightly sealed, preferably under a nitrogen blanket, as tertiary amines can slowly absorb atmospheric CO₂ and water, which can affect their activity over time.
4. Is Hegrecat PMDETA compatible with other amine and organometallic catalysts?
Absolutely. In fact, PMDETA is often used in synergistic blends. It can be combined with blowing catalysts (like BDMAEE) to achieve a balanced reaction profile, or with tin or other metal catalysts to fine-tune the back-end cure. Our technical team can help you design the optimal catalyst package for your specific application.
5. What is a typical dosage level for Hegrecat PMDETA in a rigid foam formulation?
The typical dosage level varies depending on the system, desired reactivity, and other catalysts used. However, a common starting point for rigid foam is between 1.0 and 2.5 parts per hundred parts of polyol (PHP). We always recommend starting with lab-scale trials to determine the optimal concentration for your specific formulation and processing conditions.
6. What safety precautions should be taken when handling PMDETA?
PMDETA is a corrosive liquid and a strong amine. It is essential to handle it with appropriate Personal Protective Equipment (PPE), including safety goggles, chemical-resistant gloves (e.g., nitrile or neoprene), and protective clothing. Work should be conducted in a well-ventilated area. Please refer to our Safety Data Sheet (SDS) for complete handling and first-aid information.
7. How does Hejia Chemical ensure batch-to-batch consistency?
Consistency is paramount. We achieve this through three key pillars: 1) Strict incoming QC on all raw materials. 2) A highly automated manufacturing process (DCS) that eliminates process variables. 3) Rigorous final Quality Control testing (GC, moisture analysis) on every single batch. Each shipment is accompanied by a Certificate of Analysis (COA) that guarantees the product meets our tight specifications.
