| Introduction |
|
|
|
| Woven by polyester monofilament and multifilament, it has good abrasion resistance, fire resistance and heat dissipation. It is used to provide anti-wear protection and noise suppression; the open structure is convenient for the maintenance, maintenance, modification and overhaul of the covering; suitable for Harness and pipeline system protection for traditional road vehicles and new energy vehicles. |

| Thickness change rate |
Take a sample with a length of 300mm and place it in an oven at 120°C for 24h. After taking it out, measure 5 points at approximately the same interval for thickness measurement (measurement is required before and after the experiment). Change rate = (thickness before experiment-thickness after experiment)/thickness before experiment, taking the absolute value. |

| Length change rate |
Take a test piece with a length of 100mm, place the sample in an oven at 120°C for 24h, and then take it out for length measurement (measurement is required before and after the experiment). Change rate = (length before experiment-length after experiment)/length before experiment, taking the absolute value. |

| Withstand voltage performance |
Insert a metal rod inside the self-coiling tube, wrap the outside with metal foil, and apply a voltage of 1000V between the metal conductors for 1 min. |
No breakdown |
| Wear resistance |
Apply a weight of 450g to the sample, use 150G gauze wear-resistant tape (10mm wide conductive part, maximum 150mm interval), run at a speed of 1500mm/min, when the sample wears through (the wire part is in contact with the gauze support pin), record the gauze The length of the hardband. |
