Makrolon® 2407 RE

What is it?

A polycarbonate (PC) that is extremely tough, it’s also lightweight with glass-like transparency; it is impact-resistant even at low temperatures. Makrolon® RE products use fewer fossil raw materials, as they are partially replaced by renewable feedstock made from bio-waste and residues, using mass balancing approach – meaning identical material performance compared with the fossil-based versions. They are ISCC Plus certified along the supply chain and production lines. The 2407 RE is a general purpose grade, with low viscosity, UV stability, and a luminous transmittance of 89% at 1mm material’s thickness.

Technical benefits

The advantages of polycarbonate, such as excellent impact resistance, thermal resistance, transparency, and mechanical strength are not compromised.

Look and feel

The material is available in transparent, translucent, and opaque colours.
It can easily be coloured with masterbatches. The straightness and surface quality of the sample is very good.

Environmental benefits

Makrolon® RE has a global warming potential (GWP), or product carbon footprint, from cradle to gate, of 0.5kg of CO2e (CO2 equivalent). The LCA calculation and result were critically reviewed by TÜV Rheinland. ISCC Plus certified, it has an attributed sustainable share of up to 72%, which indicates bio-circular content of up to 72%.

Applications

This thermoplastic is suitable for truly diverse applications. It is used in medical devices, automotive headlamps, sporting equipment, electronics, eyewear, architectural glazing, LED lighting, and numerous other products. This grade is a drop-in solution for those seeking high performance and best-in-class environmental performance.

Why we chose this material 

Transparent polycarbonate grades with a reduced environmental footprint are difficult to find. Usually, mechanically recycled grades experience some reduced properties, which is not an issue with this grade.

Why you should consider this material

  • You need a high-gloss transparent polymer.

  • You need a material approved for medical applications.

  • You are looking for a material with a bio-based content that substantially reduces the environmental impact in terms of energy used and CO₂ emitted.

About the manufacturer

Covestro – formerly Bayer MaterialScience – arose from the Bayer Group’s chemicals and plastics unit. The company produces precursors for polyurethane foams and high-performance plastic polycarbonate as well as precursors for coatings, adhesives, sealants, and specialty products including films. Headquartered in Leverkusen, Germany, the company has 50 production sites across the globe.
