The maximum volume change rate is no more±3%after 70 hours’ immersion in ASTM3 at 70° C
The tensile strength rate -2.5%,the elongation rate at break -2%after 70 hours?immersion in ASTM2 at 70° C
Changes in tensile strength is smaller than -14%and the one in elongation at break is smaller than -12%after 168 hours’ immersion in ASTM2 at 80° C
 
Changes in elongation at break is not greater than-25%after 168 hours’ immersion in ASTM2 at 90° C.
Changes in tensile strength is not greater than -12%and the one in elongation at break is not greater than -20%after 168 hours’ heat aging at 100° C.
Changes in tensile strength is not greater than -10%and the one in elongation at break is not greater than -6%after 168 hours’ heat aging at 100° C.
Sphere of Application
