Description

VALOX 855 is a 15% glass filled, flame retardant Polybutylene Terephthalate/Polyethylene Terephthalate (PBT/PET) injection moldable grade. It has excellent chemical resistance and a UL94V0@1.5mm flame rating. With its improved aesthetics compared to standard PBT, it is an excellent candidate for a wide variety of applications including steam irons, appliance components, and lighting parts.

This material data has been provided by Matmatch.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
