In military applications, TPU Material is gradually becoming the preferred material for the outer sheath and insulation layer of special military cables.
TPU Material, the full name of which is thermoplastic polyurethane elastomer, is a polymer material that combines the advantages of rubber and plastic. It has good flexibility, high mechanical strength and chemical resistance, and is widely used in the automotive, medical, consumer electronics and military fields.
TPU Material is mainly divided into the following according to the structure:
Polyester TPU: strong oil resistance and good mechanical properties;
Polyether TPU: good hydrolysis resistance and good low-temperature flexibility;
Fully aliphatic TPU: has super strong anti-yellowing and light stability, and is often used in outdoor applications.
Military cables must cope with various extreme environments, and the performance of the material directly determines the durability and reliability of the cable. Common performance requirements include:
1. Strong wear resistance
2. High and low temperature resistance (-40℃ to 125℃)
3. Oil and corrosion resistance
4. UV and ozone aging resistance
5. Excellent flexibility, easy wiring and storage
6. Has a certain flame retardant grade
TPU has excellent mechanical strength, with a tensile strength of 40~100 MPa, which is much higher than traditional sheath materials such as PVC and PE, and can effectively protect the internal conductor structure. TPU Material has a tough surface and has strong tear and wear resistance. Even when used in complex terrains such as sand, dust, mud and water, it can effectively protect the cable core and extend the service life of the cable.
TPU Material has excellent UV and ozone resistance, and is suitable for complex environments such as plateaus, high temperatures, and strong sunshine. This weather resistance makes it particularly suitable for military cable systems deployed in the field.
Even in extremely cold environments (such as -50℃), TPU Material can still maintain good flexibility, is not easy to break or harden, and ensures the normal operation of the cable in extreme weather.
TPU can resist a variety of oils, solvents and chemical corrosives, and is suitable for military environments that need to resist chemical leaks and fuel pollution.
Angreen TPU Material complies with flame retardant standards such as UL 94 V-0, IEC 60332-1, and EN 45545-2, and most TPU Materials are halogen-free and low-smoke materials that do not contain halogens. The smoke generated during combustion is low and the toxicity is low, which meets the dual requirements of environmental protection and safety for modern military equipment.
1. Communication system connecting wire
2. Field radar system cable
3. Tactical backpack power cord
4. UAV power transmission cable
5. Military power plug harness
In the military industry, the requirements for cable performance are constantly increasing. TPU Material has become the best solution for military cable outer sheath materials with its comprehensive and superior physical and chemical properties. In the future, with the continued demand for high-performance, environmentally friendly and lightweight materials, the share of TPU in the military cable market is expected to continue to grow.
In the future trend of intelligent, modular and unmanned military equipment, cables must not only transmit data and energy, but also bear the challenges of adaptability to higher frequencies and more complex environments.
As a "future material", TPU Material:
Can be combined with antibacterial, antistatic and anti-electromagnetic interference functions;
Supports laser marking and can be recycled;
Has been integrated with optoelectronic composite cables, radio frequency cables, and high-frequency and high-speed transmission cable technologies.
