Features: transport the oily material or use under Oily environment .
Application:grain、mineral、Recycling plant、Oil refineries and so on.
Technical data:
After the aging test(70℃*168h), at cover rubber rate of “tensile strength at breaking” and “elongation at breaking “,the value change is not over 25% than before
Grade | Breaking Strength,Mpa | Elongation At Break,% | Abrasion,Mm3 |
L | ≥14.0 | ≥350 | ≤200 |
D | ≥16.0 | ≥350 | ≤160 |
Note:L----Under the general oil resistant condition;D---Under the high abrasion and oil resistant condition | |||
Cover rubber oil resistant testing.
Note:when you test the oil resistant, choice one of oil in above is ok.
