Item | Tensile strength/MPA≥ | Elongation at break/%≥ | Abrasion/mm³ ≤ | Hardness(0) |
Properties before aging | 14.0 | 400 | 250 | 60 |
Properties after aging | 12.0 | 340 | - | 65 |
Note: when thickness of cover is 0.8mm-1.6mm, the thickness of the sample can be the maximum by cutting out, at this moment, the tensile strength and elongation at break can be lower in 15% than the data in form |
