Conclusions

The problem of the cooling of a melted polymer film on a drum with allowance for the temperature dependences of the thermophysical properties of the material and of heat-exchange with the air has been solved. The concept of an equivalent thermal diffusivity coefficient has been derived.

Formulas have been obtained for calculating the temperature field of a film and its mean temperature over its cross-section, and the equivalent thermal diffusivity coefficients of the most important thermoplastics for given cooling conditions.

Formulas have been obtained for calculating the cooling time of a film, and the diameter and rotational frequency of the cooling drum, which ensure the needed temperature uniformity in a section of the cooled film.
