Description

LEXAN 3412ECR Polycarbonate (PC) is an injection moldable non-chlorinated and non-brominated flame retardant grade that is 20% glass fiber filled. It has a UL94 V0@1.5mm rating and is available in various opaque color options. This is an alternative to LEXAN 3412R and 3412HF.

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.
