The IDES datasheet for 3412R prints a density of 1.35 g/cm3, a flexural modulus of 5520 MPa, a Vicat softening temperature of 166 °C and a heat deflection temperature of 146 °C at 1.8 MPa. The LEXAN 3413R grade, which a distributor describes as \"a 30% glass reinforced polycarbonate\", is listed with a specific gravity of 1.43 and a heat deflection temperature of 303 °F at 66 psi. Both values sets are typical datasheet values, not specification limits, and no in-orbit flight result was found for either grade.\n",
