Synocat® NEM (N‑Ethylmorpholine, CAS 100‑74‑3) is a medium‑strength tertiary amine catalyst specifically optimized for polyester‑based polyurethane flexible foam systems. It effectively promotes the reaction between isocyanate and polyol, while continuing to catalyze the gel reaction after the foam reaches its peak rise, enabling full cell expansion, faster curing, and a more uniform cell structure. With a high purity level of ≥ 99%, Synocat® NEM delivers excellent process stability and batch‑to‑batch consistency for polyurethane manufacturers.

Precise Catalysis for Higher Productivity – Fast reaction kinetics shorten demold cycles, significantly increasing production line throughput.
Excellent Surface Cure – Promotes firm foam skin formation, improving appearance and tactile quality, especially in high‑resilience (HR) foam applications.
Superior Blow (Rise) Catalytic Activity – Efficiently promotes the urea (water‑isocyanate) reaction, making it an industry‑standard blowing catalyst for flexible foam.
Optimized Foam Performance – Enhanced open‑cell structure improves air permeability, which is critical for mattress and automotive seating foams.
Dosage Efficiency & Cost Savings – Synocat® NEM typically achieves target reactivity at 10 – 15% lower dosage compared to conventional amine blends.
Excellent Batch Consistency – Strict moisture control at ≤ 0.2% ensures highly stable catalytic activity across all production batches.
Polyester‑based polyurethane flexible slabstock foam – mattresses, furniture cushioning
Automotive seating and interior foam – seats, headrests
