Angst+Pfister APSOplast® EP GM 203 (epoxy resin/glass filament mat)
Categories:	Polymer; Thermoset; Epoxy
Material Notes:	Thanks to the use of the temperature-resistant, mechanically strong epoxy resin system, this EP glass filament mat can often replace an epoxy laminated glass fabric, as well as offering a commercial advantage. Grade EP GM 203 has good resistance to seawater and chemicals, exceptional electrical properties such as high track resistance, and very good heat stability with a temperature limit of +180 °C. This meets the requirements of Heat Insulation Class H. Its mechanical strength remains unchanged over a broad temperature range. At elevated temperatures, it even has a lower loss in mechanical properties than epoxy laminated glass fabric Hgw 2372.4 and is thus often preferred. Information provided by Angst + Pfister
