Oil resistance and aging resistance		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
Oil resistance and aging resistance		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		Industrial covering for cable	soft covering for cable which excelled TP1 in non freezing and oil resistant aspects	excelled TP2 in high temperature resistant and oil resistant aspects
