Overview

Randomized trial assesses Bacopa monnieri forms' effects on RPU/PIR foam properties, suggesting potential applications.

Key Points

  • This research aims to explore how different forms and concentrations of Bacopa monnieri influence the performance of rigid polyurethane–polyisocyanurate foams.
  • Various forms of Bacopa monnieri (original powder, tea form, post-extraction residues) were used as additives.
  • The performance of the resulting RPU/PIR foams was analyzed for physical, mechanical, thermal, and flammability properties.
  • Measured properties included apparent density, compressive strength, and flammability.
  • Foams with post-extraction residues (Mf) had the lowest density and reduced brittleness.
  • Foams with original powder (Mp) exhibited the highest compressive strength.
  • Optimal Bacopa monnieri content for foam performance was between 3 and 7 wt%, with excess reducing structural integrity.
