GLS 285-056 exhibits good aging properties at 70°C for at least one week. This is illustrated by the initial and final properties after aging shown in Figure 7 indicate that GLS 285-056 exhibits good aging properties at 70°C for at least one week. The percent of change in tensile strength, elongation, modulus, and tear strength after heat aging is nominal.
