Polyurethane foam from oil palm fruit waste: synthesis and characterization of biopolyol and foam properties
… of this research is to produce of polyurethane (PU) foams with biopolyols from liquefied oil palm fruit waste (PW). Three parts of oil palm fruit waste (PW): oil palm mesocarp fiber (PM), oil palm shell (PS) and oil palm kernel (PK) was liquefied using liquefaction solvent with sulfuric acid as …

Structural characterization of polyurethane foam and implications of aging
Polyurethane (PU) foam is used as a shock mitigation material in the national stockpile, which degrades over time. A replacement foam, ReCrete was shown to exhibit acceptable mechanical properties after aging, but fractured with impact testing. Previously, processing ReCrete foam at elevated …

Characterization of Novel Urethanases and a Commercial Cutinase for the Degradation of Polyurethane
… by releasing greenhouse gases. Polyurethane (PU) is the second most abundant “hydrolysable” plastic, harboring hydrolytically sensitive functional groups in its polymer backbone. Yet only a fraction of PU waste is recycled, often through mechanical processes that downcycle waste into lower …

FRP-Based High-Performance Building Envelopes - An investigation on the environmental performance of GFRP sandwich panels
… laminate face sheet and adhered to a polymer foam core can potentially provide an integrated, loadbearing and lightweight solution for geometrically complex building envelopes. One of the barriers to their uptake is the lack of data on their durability and long-term performance in service …
