VISCOELASTIC FOAMS

A model viscoelastic foam (VE foam) formulation based on 2,4’-rich diphenylmethanediisocyanate was used to evaluate performance of TERRIN™ polyols when substituted for polyether polyols.

Depending on choice of Terrin polyol and substitution level, differentiated properties may be obtained compared to reference formulations.

Examples include:

  • Faster recovery time (most formulations)
  • Higher tensile strength (foams made using Terrin 168G and 170)
  • Higher CFD (foams made using Terrin 170)
  • Decreased glass transition temperature (Tg)
  • Testing also suggests possible slower burn rate

Testing also suggests possible slower burn rate, substituting TERRIN™ polyols into the reference foam formulation decreases Tg.
