Frequently Asked Questions

Yes, Valox™ FR1 film offers high-temperature resistance compared to many other plastic films. It can withstand continuous operating temperatures of up to approximately 167°C (333°F) without significant deformation or loss of properties. PBT film is commonly used in applications that involve elevated temperatures.

Yes, Valox™ FR1 film has low moisture absorption compared to some other plastics. It offers good resistance to moisture uptake, making it suitable for applications where dimensional stability is important, or where exposure to humidity or moisture is expected.

Valox™ FR1 comes in .005" - .030" thick on a 36" wide master rolls. Contact your local PolymerFilms sales rep to learn more about the various Valox FR1 sizes.
