Evonik Cyro LLC has introduced an acrylic with superior heat resistance, enhanced mechanical properties and exceptional surface hardness.
Acrylite hw55 is well-suited to injection molding of technical parts for high-powered lighting applications in automotive, marine, airport and medical lighting as well as in gauges and instrument panels.
The new polymer provides high light transmission and can withstand years of thermal stress in uses such as surgical lighting, street lamps and auto fiber optics. Acrylite hw55 has a heat-deflection temperature of 241° F at 264 pounds per square inch. Even after long-term exposure to heat, the polymer retains maximum transparency, said Parsippany, N.J.-based Evonic Cyro.
Other benefits are superior strength, scratch and break resistance, and processing in injection molding and extrusion with three-zone general-purpose screws.
