Politubes specializes in the thermal stabilization of polyester films, carried out using heated cylinders.

Unlike standard oven treatment, this process ensures extremely low levels of residual shrinkage to our Politherm:

• < 0.1% in the machine direction;
• < 0.03% in the transverse direction.

As a result, POLITHERM films provide superior dimensional stability and reliability, making them ideal for printed circuit board applications.
