Evonik Cyro Introduces ACRYLITE® hw55 Acrylic Polymer For High Heat Applications Requiring Excellent Lighting Efficiency

New Grade Added to Industry-Leading ACRYLITE® Line Offers Superior Heat Resistance, Enhanced Mechanical Properties, and Excellent Surface Hardness

Evonik Cyro LLC introduces ACRYLITE® hw55 acrylic polymer that provides superior heat resistance, enhanced mechanical properties and exceptional surface hardness. These excellent properties make the ACRYLITE hw55 polymer ideal for injection molding of technical parts used in high powered compact lighting applications in automotive, marine, airport and medical lighting, as well as gauge and instrument panels.

“We are proud to introduce the latest addition to the industry-leading ACRYLITE® line of acrylic polymers, ACRYLITE hw55. This new copolymer offers designers a tough acrylic with excellent light transmission qualities that withstands years of high thermal stress,” said Wolfgang Kaster, General Manager Molding Compounds. “Whether used for surgical lighting, high-intensity street lamps, or fiber optics in automobiles, ACRYLITE hw55 can take the heat.”

In applications where high heat buildup is common, materials need to withstand excessive temperature to prevent poor performance and damage, such as warping and discoloration. ACRYLITE hw55 polymer has a high heat deflection temperature of 241° F at 264 psi under load. Even after long-term exposure to heat, ACRYLITE hw55 polymer retains maximum transparency in contrast with alternative plastics on the market.

ACRYLITE hw55 polymer has superior tensile and flexural strength; good dimensional stability; and is highly resistant to breakage, scratching, and isopropyl alcohol. It can be processed on injection molding machines and extrusion lines with 3-zone general purpose screws, making it easy to integrate into most manufacturing lines. The polymer is crystal clear, but can also be custom colored upon request.


ACRYLITE hw55 polymer can be used in a variety of applications. Listed with the Automotive Manufacturers Equipment Compliance Agency (AMECA), it is well suited for transportation designs, including covers for fiber optics in automobiles, as well as for condenser lenses and headlamps in cars. It can also be used in navigation and signaling lights on boats, lighting for airfields, tunnels, and subways; and high-density street lamps. Other applications include diagnostic and surgical lighting products; platform markings on oil and offshore rigs; and for utility meter lenses/covers.
