Covestro AG is a German company which produces a variety of  polyurethane and polycarbonate based raw materials. Products include isocyanates and polyols for cellular foams, thermoplastic polyurethane and polycarbonate pellets, as well as polyurethane based additives used in the formulation of coatings and adhesives.


Makrolon® polycarbonate is extremely robust, lightweight with glass-like transparency and is impact resistant – even at low temperatures. It also has a high dimensional stability and is easily molded, yet displays excellent heat resistance with a glass transition temperature of up to 148ºC.

Key Benefits

  • Robust: Work with a tough, yet lightweight material.

  • Heat resistant:  Rely on a broad range of flame-retardant grades.

  • Transparency:  Enjoy glass-like optical quality plus standard or special colors.

  • Specialized:  Use grades approved for food contact or medical applications.

  • Versatile:  Choose from injection molding, extrusion and blow molding grades.

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.




 Heat Resistant



Bayblend® variants exhibit an excellent balance of properties, most notably high toughness – even at cold temperatures – as well as rigidity, dimensional stability, excellent creep resistance, low moisture absorption, heat resistance and high flame retardancy.

Key Benefits

  • Tough: Experience high toughness even at low temperatures.

  • Heat-resistant: Rely on dimensional stability up to 142°C.

  • Flame-retardant: Discover a wide portfolio of excellent flame-retardant grades.
