This film is often used as a separator when heating parts in an oven.

Polyester resists swelling in wet environments.

These black polyester rods protect from UV rays better than off-white polyester. Strong and semi-rigid, they won't swell in moist environments, so they're often made into valves, pump components, and spacers.

When exposed to UV rays, these cores won’t become brittle or break down. Use them to add stiffness to composite sandwiches that may be used outdoors without adding a lot of weight.

A static-dissipative coating on this polyester film prevents electrostatic discharge from damaging sensitive electronic equipment.
