ROHM's Molding Compounds business unit has launched a new high-temperature specialty molding compound, PLEXIGLAS® Optical HT, which maintains excellent optical properties even at higher long-term operating temperatures

As a member of ROHM's portfolio of polymethyl methacrylate (PMMA) molding compounds, PLEXIGLAS® Optical HT has well-balanced properties: its optical efficiency reaches the level of PLEXIGLAS® 8N, but its heat distortion temperature Higher, close to the PLEXIGLAS® Heatresist product range; in addition, it also inherits the excellent ageing resistance and durability of PLEXIGLAS®

PLEXIGLAS® Optical HT is especially suitable for the production of LED headlight optics for the automotive industry

This new specialty molding compound gives designers of automotive headlights and lighting components more creative latitude to help create a distinctive look

The long-term operating temperature of PLEXIGLAS® Optical HT is 15°C higher than the standard

Optical components used in automotive headlights, high-power floodlights and street lights usually have high requirements on materials

However, increasing the heat distortion temperature often means sacrificing even a small amount of optical performance

René Kogler, Head of Product Management Luminaires, Extrusions and Optics at ROHM, said: "PLEXIGLAS® Optical HT was launched in response to the market demand for optical components with higher heat distortion temperatures, providing greater flexibility in luminaire designs.
Flexibility

The new PLEXIGLAS® Optical HT: The long-term operating temperature is higher than the industry standard, creating new opportunities for luminaire design

Designed for high performance LED applications

PLEXIGLAS® Optical HT can be processed using a variety of standard thermoplastic processes and has excellent flow properties comparable to basic molding compounds for the production of complex optical components
.

Dr.
Rüdiger Carloff, Project Manager at Rohm Methacrylates Innovation Management emphasizes: "PLEXIGLAS® Optical HT is specially designed for high-performance LED applications and can withstand temperatures up to 105°C
.
This has been confirmed by RTI rating Certified to UL 746B
.
At the same time, it is also ideal for light pipes with long light paths
.
”

Sivakumara Krishnamoorthy, Senior Product Manager for the Automotive Industry at ROHM's Molding Compounds business unit, said: "The potential for PLEXIGLAS® Optical HT is particularly great in the automotive industry, where long light pipes and other optical components in automotive headlights are subject to high The thermal stress is very demanding and the material requirements are very demanding
.
We believe that PLEXIGLAS® Optical HT can meet the material solutions for automotive lamps and related optical components
