Professional Technical FAQ

1. What mechanism gives Hegrecat BA100 its balanced catalytic performance?

Hegrecat BA100 contains both tertiary amine groups and an ether linkage within its molecular structure. The tertiary amine groups activate the isocyanate groups through electron donation, while the ether oxygen participates in hydrogen bonding with hydroxyl groups in polyols. This dual functionality allows simultaneous catalysis of gelling and blowing reactions with exceptional precision.

2. How does temperature affect the catalytic activity of BA100?

Like most amine catalysts, Hegrecat BA100 exhibits increased activity at elevated temperatures. Laboratory testing shows its catalytic efficiency increases by approximately 2.8% per °C between 20-50°C. This temperature sensitivity requires precise control in manufacturing processes. Formulators typically compensate for temperature variations by adjusting catalyst concentration by 0.005 php per °C deviation from standard conditions.

3. What concentration range is optimal for slabstock flexible foam applications?

For conventional slabstock flexible PU foams (density: 18-40 kg/m³), Hegrecat BA100 is typically used at concentrations between 0.15-0.35 parts per hundred polyol (php). The optimal dosage depends on specific formulation parameters: higher concentrations accelerate cure but may cause tight foam, while lower concentrations extend cream time but reduce foam resilience. Pilot studies indicate 0.22 php provides optimal balance for most MDI-TDI blend systems.

4. Is BA100 compatible with alternative blowing agents and low-GWP systems?

Yes, Hegrecat BA100 demonstrates excellent compatibility with next-generation blowing agents including HFOs (1233zd, 1336mzz), water, and liquid CO₂. Research published in Cellular Polymers Journal confirms it maintains catalytic efficiency in formulations with up to 15% water content. For HFO-based systems, combining Hegrecat BA100 with specialty siloxane surfactants yields optimal cell structure with 50% reduced thermal conductivity variation.

5. What handling precautions are required for BA100?

As an amine catalyst, Hegrecat BA100 requires standard chemical handling protocols: chemical-resistant gloves (nitrile or neoprene), eye protection, and adequate ventilation. Though it has relatively low volatility (vapor pressure: 0.25 hPa at 20°C), working in well-ventilated areas or with local exhaust ventilation is recommended. Storage should be in original sealed container111s below 30°C, separated from strong oxidizers. The flash point of 75°C necessitates appropriate fire prevention measures.

6. How does BA100 impact foam flammability characteristics?

When incorporated at recommended dosage levels (≤0.5 php), Hegrecat BA100 has minimal impact on foam flammability parameters. Testing according to ASTM D4986 shows no significant alteration in critical flammability metrics (ignition time, burning rate, smoke density) compared to non-catalyzed reference systems. However, formulators should conduct comprehensive fire performance testing when making significant formulation changes.

7. What quality control parameters are critical for BA100 consistency?

Five key parameters ensure batch-to-batch consistency: (1) Amine value (range: 650-700 mg KOH/g), (2) Water content (≤0.15% by Karl Fischer), (3) Color (APHA ≤15), (4) Specific gravity (0.89-0.92 at 25°C), and (5) Purity (≥98.5% by GC analysis). Hebei Hejia Pharmaceutical Technology Group employs ISO 9001-certified QC protocols with batch traceability and certificates of analysis for all shipments.
