The uniqueness of Apec® is its outstanding transparency and brilliance paired with a high resistance to heat. It also offers an excellent high-gloss surface for applications such as metallization. This linear, amorphous copolycarbonate can withstand temperatures between approx. -30°C and approx. 150°C for extended periods. It is also tough and resistant to impact.

Key Benefits

  • Heat resistant: Withstands temperatures between -30°C and +200°C.

  • Glass-like transparency: An attractive replacement for glass, that is lighter and stronger.

  • Design freedom: Available in clear, transparent, opaque and specialty colored formats.

  • Flame-retardant: Retardant grades comply with UL 94’s V-0 rating at 1.5 mm thickness.

  • Best surface quality: High-gloss surface suitable for metallization in vacuum or wet coating.
