PLEXIGLAS® MOLDING COMPOUNDS FOR OPTICAL APPLICATIONS, ELECTRONICS AND COMMUNICATION

PLEXIGLAS® molding compounds are the material of choice whenever light needs to pass through covers unobstructed, illuminate large light guides or reach its intended destination with precision through delicately structured lenses. Röhm’s brand polymethyl methacrylate (PMMA) also adds surprising effects to displays and gives electronic devices an elegant look.

BENEFITS OF PLEXIGLAS® MOLDING COMPOUNDS FOR OPTICS, ELECTRONICS AND COMMUNICATION

Optical purity and the high light transmission it provides are a decisive factor in selecting the right materials for optical applications, electronics and communication. PLEXIGLAS® molding compounds impress with high transparency and a light transmission of up to 92 percent. This unexcelled transparency is only reduced by the reflection loss of four percent each on the light entry and exit surfaces, due to physical factors. In combination with the good flow properties and high reproduction accuracy of even the smallest structures, PMMA enables the production of sophisticated lenses and delicately structured surfaces. PMMA’s high transparency and excellent transmittance are also invaluable when used in display covers and measuring devices, as well as for visual aids and magnifying glasses.

At the same time, PLEXIGLAS® molding compounds give manufacturers freedom of design – since the material is absolutely crystal clear in its initial form, it can be colored at will. Examples include PMMA covers colored in neutral gray that only become visible when turned on, or black, high-gloss molding compounds formed into elegant frames and pedestals for televisions or computer monitors.

PLEXIGLAS® molding compounds from Röhm provide these benefits for optical applications, electronics and communication:

  • High brilliance and transparency (92% light transmittance)
  • High reproduction accuracy
  • Highest surface hardness of all thermoplastics
  • Outstanding UV and weather resistance
  • High abrasion resistance
  • Can be processed with all common thermoplastic processes
  • High chemical resistance and easy to clean
  • Absolute colorlessness, for precise and virtually unlimited coloring options
  • Long-lasting color stability
  • 100% recyclable

PLEXIGLAS® molding compounds for the highest optical demands

Simply brilliant – their high optical purity and unexcelled light transmittance make PLEXIGLAS® molding compounds ideal for meeting the highest optical demands in optics and display applications. Offering precise processing and precise mold surface reproduction, the material enables the production of structured surfaces and even large PMMA lenses. The light-guiding properties of PLEXIGLAS® create high luminance in back-lit units – while the high transparency gives an unobstructed view of the information shown behind display covers.

PLEXIGLAS® molding compounds for hidden displays

A “secret-until-lit” function or “black panel” effect is when a dark, high-gloss cover, for example on a hi-fi unit, can transform into a display. PLEXIGLAS® molding compounds in special neutral gray colorings are ideal for this. Display covers made from these special molding compounds can accurately show the entire color spectrum of the LEDs behind them.

PLEXIGLAS® molding compounds for long-lasting components

Components for optical applications, electronics and communication made from PLEXIGLAS® molding compounds ensure a perfectly clear view and high-quality look that last. From low-maintenance covers for touch displays to high-gloss housing parts for electronic devices, from robust lenses for reading glasses to unbreakable vials in spirit levels: PLEXIGLAS® provides the best possible protection for long-term use. After all, PMMA has the highest surface hardness of any thermoplastics and is resistant against a wide variety of chemicals. Modified to be impact-resistant, PLEXIGLAS® Resist combines the proven benefits of the basic types with higher impact resistance and improved break resistance or stress crack resistance. Components made from PLEXIGLAS® molding compounds are also resistant to UV and weathering, remaining transparent and colorless or colorfast.

PLEXIGLAS® is the resource-efficient solution

PLEXIGLAS® molding compounds contribute to sustainable product design: PMMA is not only extraordinarily durable, it is also completely recyclable – in almost identical quality. Manufacturers can recycle and use post-industrial PMMA waste in their own production processes or choose PLEXIGLAS® proTerra M5 molding compounds containing 30% recycled material, thereby reducing their product carbon footprint. PLEXIGLAS® proTerra 8N molding compounds also reduce resource consumption and CO2 emissions by replacing fossil raw materials with ISCC-PLUS*-certified raw materials – without sacrificing any of the material’s proven performance.
