Ethylene-vinyl acetate copolymer definition

In many cases, the value of PE is considered as -21 °C. Actual values may be observed between -120 and -20 °C depending on the frequency/heating rate. In the case of copolymers, is strongly dependent on comonomer content. For example, ethylene-vinyl acetate (EVA) copolymers with -50% VA content exhibit T values of -109 °C, while for a VA content of 10-20%, has values between -32 and -10 °C. T ie Vicat softening point (see Section 3.4.5 for definition) is 95 °C for LDPE and 120 °C for HDPE.
