Flexible PU foam was synthesized by using recycled PU foam polyol (Infrigreen) which contain 4 functionality obtained from glycolysis wasted PU foam, as a polyol. PU foam is prepared by incorporation of recycled PU foam polyol 2, 4, 6, 8 and 10wt% in petrochemical polyol (CARADOL.SA34-05) which contain 2 functionality. Triethlylenediamine (TEGOAMIN 33) was used as the gelling catalyst. Polyether modified...
Generally, the flexible polyurethane foams were synthesized by mainly petroleum-based polyols. In this present study, Caradol SA34-05 (petroleum-based polyol) was replaced by Emerox® 14001 (natural oil-based polyol) with 0-50 wt% replacement to prepare flexible polyurethane foam by one shot method. The NCO index (NCO equivalent/OH equivalent) was fixed at 1.00. The characteristic times such as cream...
