JEFFCAT® LE-340

JEFFCAT® LE-340 Catalyst is a novel amine catalyst designed for polyether flexible high-resiliency (HR) molded and slabstock polyurethane formulations for automotive foam applications. JEFFCAT® LE-340 Catalyst is a reactive gelling amine catalyst that combines low emission potential with low foam odor. JEFFCAT® LE-340 Catalyst is a unique gelling amine catalyst that supports the isocyanate-polyol gelling reaction in polyurethane formulated systems. It enables the production-scale manufacture of various automotive foam grades of polyether flexible HR molded and slabstock polyurethane foams across high and low-density ranges.

Benefits
  • High Purity – JEFFCAT® LE-340 catalyst is high in purity, resulting in improved emissions contributed by the amine catalyst.
  • Lower Use-Level Requirement – Due to the effectiveness of JEFFCAT® LE-340 catalyst, the usage level requirement is decreased when compared to other commercially available low emission amine gelling catalysts.
  • No Contributions to VDA-278 – Utilizing JEFFCAT® LE-340 catalyst typically results in lower polyurethane foam emissions vs. conventional, non-reactive gelling amine catalysts.
  • Reduced Foam Odor – Polyurethane foams produced with JEFFCAT® LE-340 catalyst have lower post-cure odor compared to conventional non-reactive gelling amine catalysts.
