Celebrating its 90th anniversary in 2023, PLEXIGLAS®, the brand polymethyl methacrylate (PMMA) from Röhm is showcased in ChinaPlas 2023 in innovative applications for the challenges of our time for the automotive industry, lighting industry, household appliances and medical industries.

Since it had replaced glass in the mid-1950s, PLEXIGLAS® molding compounds have been used in covers for taillights for over 70 years. Over time, the small, functional lights have been transformed into complex components for brand-typical signature lights – and Röhm has also continued to develop its customized portfolio of special molding compounds to meet this demand. The company produces transparent molding compounds in signal colors or crystal clear variants, as well as versions with heat deflection and light-scattering properties. 

Today, when vehicles have become electrified and intelligent, full-width strip taillight are an increasingly popular choice, but they also have possible issues of chemical stress crack. In response, Röhm has offered chemical-resistant PLEXIGLAS® special molding compounds to improve the yield and durability of complex automotive lights, helping customers in the automotive parts industry reduce costs and increase efficiency.

The design of vehicle front ends is also changing, with long light guides, high-gloss panels and logos replacing chrome. A vehicle front requires particularly robust materials that have been impact-modified. For illuminated applications, the PLEXIGLAS® Resist special molding compound meets both optical and mechanical requirements. In high-gloss panels at the front of the vehicle, PLEXIGLAS® Hi-Gloss is a robust and resource-efficient alternative to components that need additional painting. Its high weather resistance properties ensure a sophisticated appearance that lasts – one that has long become part of vehicle design with other non-transparent pillar covers.

Neutral gray PLEXIGLAS® molding compounds achieves the black panel effect, which transforms a black surface into a true-color display and gives automotive designers exciting new design options for vehicle lighting. This is heralding a new trend in the premium sector: extraordinary taillights which only become visible when turned on. When the vehicle is turned off, they are not visible as separate components but are black and glossy panels that are seamlessly integrated into the vehicle body. 

Röhm presents a newly developed neutral gray PLEXIGLAS® molding compound with an increased light transmittance in the red spectrum. With this, automotive suppliers can achieve the signal red needed to meet requirements for vehicle lighting with fewer LEDs, or with LEDs that require a lower energy intensity and thus contribute to sustainability.

PLEXIGLAS® 8N plus simplifies the manufacturing of complex injection-molded parts. With same proven properties, such as excellent light transmittance, very high UV and weather resistance and excellent flow properties during processing, the new product boasts added application-specific benefits for molded parts with complex geometries.

Röhm has been actively promoting and advancing sustainability development, making sustainability an integral part of our business strategy. Röhm has set itself the goal of significantly reducing carbon dioxide emissions by 2030. By 2050, Röhm aims to have climate-neutral production and eliminate all of its greenhouse gas emissions.

The company has set itself the goal of significantly reducing carbon dioxide emissions by 2030: we will reduce the carbon footprint of the products by 30% per ton compared to 2020. By 2050, Röhm aims to have climate-neutral production and eliminate all of its greenhouse gas emissions.

PLEXIGLAS® is sustainable by design: PMMA molding compounds are not only 100% recyclable, but their extraordinary weather resistance means that they are very durable, and thus help to save resources.
