TPU Thermoplastic Polyurethane cable jacket material is a high-performance material used for cable jackets.
It has been widely used in the fields of data transmission and communication due to its unique physical and chemical properties.
Features
1. Abrasion resistance:TPU materials have excellent abrasion resistance, which is essential for the long-term stability of optical cables in various environments.
2. Flexibility:TPU can maintain flexibility even under low temperature conditions, which helps the installation and maintenance of optical cables in cold environments.
3. Chemical resistance:TPU is resistant to many chemicals, including oils, acids and alkalis, which makes it suitable for use in chemically polluted environments.
4. Weather resistance:TPU can resist the erosion of ultraviolet rays and ozone, keep the material performance from deteriorating, and is suitable for outdoor use.
5. Hydrolysis resistance:TPU has low permeability to moisture and can protect the inside of the optical cable from moisture damage.
6. Flame retardancy:By adding flame retardants, TPU can be made into cable jacket materials that meet different flame retardant standards, such as UL standards or IEC standards.
7. Environmental protection:TPU is a recyclable material that does not contain harmful substances and meets environmental protection requirements.
Applications
1. Communication optical cable: used to protect optical fibers from physical damage and environmental impacts, ensuring the stability of data transmission.
2. Industrial automation: In automation equipment and robotic systems, TPU-sheathed cables can withstand frequent bending and twisting.
3. Automotive cables: used for cable protection inside cars, such as connecting wires for sensors and actuators.
4. Medical equipment: In medical equipment, TPU-sheathed cables can provide the necessary flexibility and biocompatibility.
5. Energy and infrastructure: In wind power, solar energy and other renewable energy systems, TPU sheathing materials can protect cables from harsh environments.
