Abstract

An investigation was conducted to analyze the impact of incorporating polyurethane polymer's particles at different weight ratios (0.5, 1, 3, 5, 7,10 and 15) wt. %, on the polyester polymer's mechanical properties and thermal conductivity coefficient. The thermal conductivity coefficient of the samples was calculated using Holmarc's Lee's Disc apparatus device. The mechanical properties like compressive, tensile, and bending strengths were measured using a universal machine. The results indicated that increasing the polyurethane foam (PU) ratio leads to an improvement in the thermal insulation ability due to a decrease in the value of thermal conductivity, the addition of polyurethane foam enhances the ability of thermal conductivity at the ratio 7 wt. %, with a value equal to 0.175 W/m ºC, by increasing the thermal conductivities of the sample, while the result indicated a decrease in the thermal conductivity at the ratio 15 wt. %, with a value equal to 0.155 W/m ºC. Also, adding these percentages led to a rise in the values of the mechanical qualities represented by the elongation, especially at the ratio of 10 wt. %, with a value equal to 1.9 %, and tensile strength increases at a ratio of 15 wt. %, with values equal to 18.9 MPa.
