Classification and selection of TPU wires and cables
Classification of TPU cables: power energy cables, communication cables, geographic exploration cables, automotive cables, industrial cables. Others: spring wire, retractable wire, image and audio wire, medical.
The main classification description of TPU cable:
Wire and cable raw materials, have you chosen TPU?
Comparison of characteristics of polyurethane TPU, EPDM, and PVC in cable applications
The cable sheath of TPU has:
Unparalleled hardness
Low temperature flexibility
Abrasion resistance
Environmental and weather resistant
These excellent mechanical and physical properties extend the durability and service life of the cable.

Processing performance
|
The mechanical strength is extremely high, the processing performance is excellent, no vulcanization is required, and the extruder that extrudes PVC can be used to extrude TPU (the screw length is greater than 1:25)
|
The performance before vulcanization is very poor, and the strength is low after vulcanization, which is only equivalent to one third of TPU. After adding fire retardant to make flame retardant, the strength is worse
|
The soft grade contains a lot of plasticizers without exception, has poor low temperature resistance, and plasticizers may migrate, which is not environmentally friendly
|
|
Use environment
|
Except for use in general environments. Use in harsh environments: For example, dynamic cables have high-strength requirements, and need to be wound, twisted or dragged in rocks, ground, desert, ice and snow, or immersed in water with great temperature difference between day and night, etc.
|
It is not suitable for use in general environment, and is not suitable for areas that require higher strength and higher wear resistance. At the same time, its flame-retardant model has lower strength, which limits its use
|
It is not suitable for use in general environment, which requires environmental protection, wear resistance, fatigue resistance, and low temperature resistance, and its soft grade contains a lot of plasticizers
|
The cable sheath of TPU has:
Unparalleled hardness
Low temperature flexibility
Abrasion resistance
Environmental and weather resistant
These excellent mechanical and physical properties extend the durability and service life of the cable.
