PC-FR is a specialist polycarbonate for protective casings, electronics and industrial components where flame propagation is part of the risk assessment. The reference grade passed UL 94-2023 V-0 testing and combines that behaviour with 113°C HDT and unusually high impact strength.
Material family names are not specifications. This page anchors the discussion to a named commercial grade and published printed-specimen data, then translates that data into practical selection and design guidance.

Choose PC-FR when flame behaviour is a defined requirement alongside toughness and useful heat resistance.
Orientation, conditioning and geometry can move finished-part performance materially. Use these figures to compare candidate materials—not as guaranteed minimums.

XY values normally represent flat-printed specimens. Z-direction strength can be substantially lower. Final production settings should be qualified on representative geometry.
A useful material choice starts with load case, temperature, environment, duty cycle and failure consequence—not the strongest number on a datasheet.
