Rigid PVC (uPVC) compounds read for this profile have a specific gravity of 1.32 to 1.54 and a tensile yield strength of 38.2 to 53.4 MPa, and they deflect under a 1.8 MPa load at 57 to 72.2 °C. Flexible (plasticised) grades reach 330 to 430 % elongation at break, and two cable grades are rated to 60 °C continuous use in air.",
