Abstract

Ujawniono sposób wytwarzania poliuretanowej pianki auksetycznej o wydłużonym czasie powrotu w stosunku do pianki wiskoelastycznej, z której ją wytworzono, charakteryzującej się ujemnym współczynnikiem Poissona przy naprężeniach ściskających. Przed każdym następnym stopniem kompresji piankę wyjmuje się z formy i rozciąga się ręcznie do co najmniej 60% objętości pianki w stosunku do objętości pianki w stanie wyjściowym.A method for producing polyurethane auxetic foam with an extended recovery time is disclosed relative to the viscoelastic foam from which it was made, which has a negative Poisson's ratio at compressive stresses. Before each subsequent degree of compression, the foam is removed from the mold and stretched manually to at least 60% of the foam volume relative to the foam volume at the initial state.
