The examples and comparative examples were tested on an Oscillating Disc Rheometer (ODR), where Δ T is the difference between Tc90 and Tc10, a parameter commonly used to measure cure rate, with smaller values indicating higher cure rates.
Tensile strength tests and abrasion resistance tests were conducted on the examples and comparative examples.
| ΔT(min) | Tensile strength (Mpa) | Volume of abrasion (cm)∧3) | |
| Example one | 7∶10 | 20.5 | 0.401 |
