Exploring the Effects of Composition and Thickness Variations on Polyurethane Density in Fishing Vessel Hatches as an Insulation Material: A Comprehensive Study

Good Handling Practices (GPH) for fish will have an impact on the quality of fish catches. Therefore the addition of material as a good insulator in the hatch of a fishing vessel is needed. Polyurethane as an insulator material can be used as one of the additional materials in the hatch of a fishing vessel. This study aimed to compare the thermal conductivity properties of the composition and thickness of polyurethane. The results will find out how the influence of composition and thickness of polyurethane affect the insulation of the fishing vessel hatch. The ideal polyurethane insulation should have a material density ρ ≥ 30kg/m 3 . Density values from testing variations in polyurethane composition show density values in the range of 40kg/m 3 -100kg/m 3 , this outcome meets the criteria for a high-quality polyurethane insulating material.
