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.

Voltage resistance

Self-rollig tube with metal rod inserted inside and metal foil wrapped outside, 1,000V voltage applied between metal conductors for 1min.

No breakdown

Abrasion resistance

Apply 450g of weight on the sample, use 150G gauze abrasion resistant tape (10mm wide conductive portion, maximum 150mm spacing), and run at a speed of 1,500mm/min. When the sample is worn through (conductor portion is in contact with the gauze support pins), record the length of the gauze abrasion resistant tape.
