Our Makrolon® portfolio for lighting applications

Our wide range of Makrolon® products meet the needs of luminaire manufacturers when it comes to creating energy-efficient lighting solutions that are both sustainable and effective. Depending on the application, this requires high lumen efficiency per watt, light guiding or thermal conductive properties, flame retardancy, or a multifunctional design. 
 
The Covestro portfolio includes transparent, translucent, reflective white, light blocking, thermal conductive, and flame retardant grades:
 
Makrolon® LED: Upmost transmission (> 90%) to improve efficacy for transparent luminaire covers, lenses, light guides, or other optics. 
Makrolon® DQ: Three levels of translucency with maximum transmission, offering individually suitable opacity for your luminaires. 
Makrolon® RW: Ideal surface for reflectors in aesthetic white with up to 97% diffuse reflection in all directions. Easy for the eyes without glare and available as a light- blocking variant to avoid light leakage. 
Makrolon® TC: Maximized thermal conductivity for plastic solutions, e. Enabling the replacement of metals in heat sinks with less weight, more design freedom, and an energy- efficient production. 
Makrolon® FR: Flame retardant variants of LED, DQ, RW, and TC products for high demands on light and safety. Special solutions also for high requirements in rail, aircraft or other public transportation applications.

More sustainable material solutions in the lighting industry

Sustainability is a central aspect of Covestro's strategy. Our polycarbonate solutions for lighting applications enable energy-efficient and long-term stable systems with significantly lower weight than glass or aluminum products. In addition, alongside fossil-based production, our core products are also available as Makrolon® RE grades. These are manufactured using raw materials from ISCC Plus certified mass-balanced biowaste and residual materials, as well as renewable energy, and enable significant CO2 savings.
