An inspirational brand for 90 years

PLEXIGLAS® has been an inspiration since its very first application – after all, the brand polymethyl methacrylate (PMMA) from Röhm is the material of choice for creative designs and innovative projects thanks to its versatile properties and intelligent functions.

Recycling of PLEXIGLAS®: Post-consumer recycling of back-light units of PMMA screens

Backlight units of screens are often made of high-purity polymethyl methacrylate (PMMA) and are therefore ideal for chemical recycling. In this process, the polymer (PMMA) is returned to the monomer (MMA) by heating, which can then be used as a raw material for polymerizing PLEXIGLAS® or other products such as reactive resins.

Products made from this have a significantly reduced carbon footprint compared with virgin material. This process clearly distinguishes PMMA from other materials where chemical recycling only produces precursors for monomer production, such as pyrolysis oils.

Nomenclature change for light diffusing products

Röhm is constantly aiming for better quality and innovations for our products, but also for better solutions along the entire customer journey. This is why we are changing the nomenclature for light diffusing molding compounds from January 1st 2023.

PLEXIGLAS® makes even red lights green.

PLEXIGLAS® has the ability to take on any color – while also remaining green. At its basic structure, PLEXIGLAS® contains no halogens, no aromatic compounds, and no plasticizers. It is nontoxic, noncarcinogenic, and nonmutagenic. Best of all, at the end of its life, it is fully recyclable. PLEXIGLAS® is the material of choice for your green products.

For PLEXIGLAS®, reincarnation is old hat. We call it “recycling.”

We believe in reincarnation. The reincarnation of PLEXIGLAS®, at least. Because PLEXIGLAS® is so pure that it can be broken down into its basic components again to be reborn as new PLEXIGLAS®. Few plastics can achieve a rebirth of this kind – this is not downcycling, but true recycling in the interests of a circular economy!

PLEXIGLAS® Optical HT

The universe created the sun. All other lights can be created with PLEXIGLAS®.

The great thing about PLEXIGLAS® is that it is always in impressive shape – to be specific, in precisely the shape you require. That’s because our high-performance plastic can be individually formed, making it possible to create entirely new lighting concepts. PLEXIGLAS® also outshines conventional materials in terms of transparency and durability.
