Thickness change rate |
Take a 300mm long sample and place it in an oven at 120°C for 24h. Take it out from the oven, measure its thickness at 5 points at approximately equal intervals (measuring both before and after the experiment). Rate of change = (Pre-experiment thickness - Post-experiment thickness) / Pre-experiment thickness, taking the absolute value. |
≤10% |
|
Length change rate |
Take a 100mm long sample and place it in an oven at 120°C for 24h. Take it out and measure the length (both before and after the experiment). Rate of change = (Pre-experiment length - Post-experiment length) /Pre-experiment length, taking the absolute value. |
≤10% |
