About High-Temperature PC
-
High-temperature PC is the trade name for copolycarbonate (PC-HT), a product family developed from polycarbonate. Its unique combination of high heat resistance, toughness, transparency, light stability and flow sets it apart from any other engineering thermoplastic. Its heat resistance is particularly outstanding, with some grades withstanding temperatures up to 260 ℃. This makes it an ideal material for molded parts used under high thermal stress, where general-purpose polycarbonate is no longer suitable.
Available Transparent High-Temperature PC Grades
-
- 150 ℃ grade, typically used for steam sterilization without shrinkage
- 160 ℃ grade, typically used for overmolding without deformation
- 180 ℃ grade for LED secondary lenses
- 200 ℃ grade for automotive lamps and other high-temperature applications
- 260 ℃ grade, suitable for SMT reflow soldering
