Flexible Foams with Improved Thermal Comfort

Gist”: Gelatinous styrenic block copolymers are incorporated in flexible foams to increase thermal conductivity.

Why it is interesting: High viscosity styrenic triblock copolymer resins (like SBS, SEBS, SIS etc), plasticized with mineral oils, are added to flexible foam-forming compositions. The heat of the foam-forming reaction is said to be sufficient to further polymerize the resins and melt the styrene-block such that the block copolymers get integrated into the polyurethane matrix. The resulting foams show increased load bearing and improved thermal conductivity. These systems could improve the thermal comfort properties of cushioning materials, especially those of viscoelastic foams.
