Softening temp of ldpe

WebThe Vicat softening point is the temperature at which a flat-pointed needle penetrates the sample to a thickness of 1 mm when loaded with a 10 N or 50 N load. In the test, the sample is placed in an oil bath that is heated at a rate of 50 °C/h or 120 °C/h, and the needle is placed on the surface of the sample. http://www.lgchem.com/upload/file/chinaplas/Division_Info/PO_vf.pdf
