Partial replacement of toluene diisocyanate (TDI) on mechanical properties of old newspaper filled diphenylmethane diisoeyanale (MDI) foam composites

Abstract

The mechanical properties of partial replacement of toluene diisocyanate (TDI) in diphenylmethane 4,4’-diisocyanate of old newspaper (ONP) foam composite based on polyurethane (PU) was investigated. The results indicate that an increase of ONP filler content leads to an increased compressive strength, elastic modulus and hardness. At constant ONP content, foam composites produced by partial replacement of TDI in MDI result in higher values of hardness, compressive strength and elastic modulus compared to the ONP foams control.
