Softening temperature

is usually determined for films on plastic sheets according to Vicat.

The value describes the temperature at which a defined test specimen sinks into the sample under defined pressure in a given time. As an example, PP materials showed values somewhat 3 x higher than PE-LD.A 50: with a force of 10 N and a heating rate of 50 °C/hA 120: with a force of 10 N and a heating rate of 120 °C/hB 50: with a force of 50 N and a heating rate of 50 °C/hB 120: with a force of 50 N and a heating rate of 120 °C/h
