Tear Resistance XLPE

The material properties related to the crack resistance of the cable mainly include the following items:

1. Low-temperature shock:

Low-temperature embrittlement impact is an important index to evaluate the low-temperature performance of cable materials. Polyolefin Cable Compound

The low-temperature performance of pure polyolefin materials is better, the low-temperature embrittlement impact temperature of pure polyolefin materials should be below -70℃, and the low smoke halogen-free polyolefin cable materials can basically pass the low-temperature embrittlement impact of -40℃.

2. Aging:

Thermal aging is to put the material into a thermal aging box to examine the changes in mechanical properties at a certain temperature and time.

After thermal aging, the properties of the material will generally decline. Thermal aging is an important indicator of the cable material, and it is also the basis for judging the temperature resistance level of the cable. For example, the temperature resistance level of the cable is 70°C, 90°C, 105°C, 125°C, etc., which are distinguished according to the thermal aging conditions. If the aging performance is poor or does not meet the temperature resistance level, the cable will crack.

ATP's xlpe material totally solves those problems and makes the cables with good tear resistance.
