Valox™ FR1 is a flame retardant PBT (Polybutylene Terephthalate) known for its good dimensional stability, high heat/chemical resistance, and high tensile strength. It has more economical molding characteristics than other thermosets. Valox FR1 offers a UL94 VTM-0 performance down to .005″ thick.
Valox FR1’s dielectric strength and ease of fabrication make the material most common in the transportation and electronics industries.
Versatile for large-scale production of in-mold decorations
They do not melt or deform when used as a carrier for hot-stamping foil
With better thermal stability than PETG and PVC, diagnostic strips made with Melinex® ST329 retain their shape and stability at temperatures up to 446°F (230°C) for registration during strip printing

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.
