Heat-Resistant Grade PMMA
Heat-resistant grade PMMA is produced by copolymerizing heat-resistant monomers (such as maleic anhydride MAH, cyclohexyl methacrylate CHMA, etc.) or adding heat-resistant fillers, raising the heat deflection temperature to 105~130°C, with some high-end grades reaching 140°C. This series is specifically developed for transparent components requiring long-term high-temperature resistance, such as automotive headlamp lenses, water heater windows, and HVAC panels.
