ESO-01 HDPE
High-density polyethylene (HDPE) or polyethylene high-density (PEHD) is a polyethylene thermoplastic. The mass density of High-density Polyethylene can range from 0.93 to 0.97 g/cm³. The difference in strength exceeds the difference in density, giving HDPE a higher specific strength.[3] It is also harder and more opaque and can withstand somewhat higher temperatures (120 °C/ 248 °F for short periods, 110 °C /230 °F continuously).
