Information

It is well known that charging cables have certain requirements on the environment. Because the cable of charging car is exposed outdoors for a long time, it will encounter sunlight, humidity and freezing, etc., so it needs the cable material to have UV resistance and low temperature resistance, and it must have certain softness and high temperature resistance and aging resistance, and it has halogen-free flame retardant and low smoke density when burning. The TPU material of thermoplastic elastomer just meets these conditions. Here is a brief introduction to the application advantages of TPU material of thermoplastic elastomer in charging cable.

Comparison of performance of jacket material TPU with other materials

Cable sheath refers to the outermost layer of the cable, also known as the outer cover. Play the role of isolating the internal insulation layer and the outside world, prevent insulation from moisture, so that the internal from mechanical damage. Therefore, there are strict requirements for sheath materials in the use of cables.

TPU(thermoplastic polyurethane elastomer) is a special elastomer with a wide range of hardness, and can still maintain good elasticity and toughness under high hardness; In addition, the proportion of TPU is low, only 1.0-1.2g /cm3, the same weight of materials to prepare more products, more economic.

Charging pile cable TPU sheath generally refers to polyether TYPE TPU, because polyether type TPU strength, hydrolysis resistance and low temperature performance will be better.

Charging pile cable TPU sheath generally refers to polyether TYPE TPU, because polyether type TPU strength, hydrolysis resistance and low temperature performance will be better.

 

1. In terms of mechanical properties, the tensile strength of polyether TPU is far superior to other sheath materials, which is above 25Mpa; The elongation is more than 500%, with good bearing capacity, impact resistance and shock absorption performance;

 

2. In terms of temperature performance, TPU is superior in low temperature resistance, which can reach -50℃, which can fully meet the cold environment in the north;

 

3. Tearing strength greater than 80kN/m can effectively prevent sheath cracking;

 

4.TPU sheath is halogen-free and flame retardant, which will not pollute the environment.

 

5.TPU is also extremely superior in buckling resistance, wear resistance, oil resistance, hydrolysis resistance and weather resistance;

 

The application advantages of TPU in charging cable are introduced above. To sum up, from the comparison of performance data of different sheath materials, polyether TPU as the sheath material of charging cable does have great advantages.
