Description

PolyMax™ PC-FR: Flame Retardant, High-Performance Polycarbonate

Advanced Flame Retardancy
PolyMax™ PC-FR is formulated with Covestro’s Makrolon® polycarbonate, achieving V0 performance in the UL94 flame retardancy test. This makes it a top choice for applications where fire safety is critical.

Outstanding Mechanical and Thermal Properties
Engineered for demanding environments, PolyMax™ PC-FR delivers excellent toughness, high strength, and superior heat resistance—ensuring reliability in challenging conditions.

Ideal for Specialized Industries
With its unique combination of flame retardancy and mechanical performance, PolyMax™ PC-FR opens new possibilities in the automotive, railway, and aerospace sectors, where stringent safety and durability standards are required.

Perfect for Safety-Critical Engineering Applications                                                      Choose PolyMax™ PC-FR when your project demands top-tier flame resistance alongside strength, toughness, and heat stability - ideal for advanced industrial and transportation components.

Please refer to the printing requirements below before purchasing. 

Printing Requirements

  • All-metal hotend that can reach at least 260˚C.
  • Enclosed printer that can trap heat required.
  • Actively heated chamber with minimum 90˚C chamber temp required.
  • Large, dense parts will require a heated chamber even more so than small parts.
  • Annealing post printing. More info on annealing: https://us.polymaker.com/blogs/3d-printing-tips/what-is-annealing-and-why-do-we-do-it
  • Dryer or drybox recommended.
  • Magigoo PC highly recommended to help with bed adhesion.
  • All-metal hotend that can reach at least 250˚C recommended

Frequently Asked Questions

Got questions? We've got answers. From choosing the right material to caring for your spools, here's everything you need to know in one spot.

Has PolyMax™ PC-FR been tested by a third-party?

Yes, PolyMax™ PC-FR has been tested by SGS-CSTC Standards Technical Services Co., Ldt.

Test Method:
IEC 60695-11-10:2013/Cor.1:2014 Method B

Result:
Classification: V-0

Full test report here.

Does the FR affect the mechanical properties?

Yes, the FR additive will make the material less ductile which means a higher tensile strength and Young's modulus (more rigid). However the PC will maintain its great impact and high heat resistance.

More information in the technical data sheet below.

What is annealing?

You can find out more about annealing HERE

Will the spools work in an AMS?

Yes! We have redesigned the edges of our spools so all Polymaker products will now spin great in the AMS.

Does PC absorbs moisture?

The short answer is yes, PolyLite™ PC will absorb moisture slightly faster than regular PLA. We recommend using a dry box to achieve high quality and strong prints.

Why are my parts cracking along layer lines?

You really need to make sure you are using an enclosed printer and that you are keeping ambient air temps as high as possible. You then want to make sure you are annealing the part the moment the print finishes. Keeping ambient air temps high and allowing for very slow cooling is a great way to reduce chances of cracking and to maintain layer strength.
