TPU pellets Material 

·TPU is the abbreviation of thermoplastic polyurethane, which is divided into polyester type and polyether type.

·TPU materials can be used to produce wire and cable materials through various polymer processing technologies (such as injection molding and extrusion), and have the characteristics of high and low temperature resistance, flame retardancy, wear resistance, oil resistance, etc.

·TPU has many advantages over PVC.

·At low temperatures, TPU materials will still remain soft, while PVC will harden.

·At room temperature, the plastic smell of PVC is more obvious, while TPU has basically no smell.

·TPU can be recycled and is an environmentally friendly material.

·It is widely used in the manufacture of wires and cables in the fields of new energy vehicles、charging piles、marine floating cables、equipment、wire plugs、medical cables, etc.

TPU cable materials, namely thermoplastic polyurethane cable materials, have been widely used in the cable industry due to their excellent physical and chemical properties. TPU has excellent wear resistance, oil resistance, hydrolysis resistance, weather resistance, and good flexibility and elasticity, which make TPU cable materials suitable for various environmental conditions, including dynamic applications and harsh environments.

The main categories of TPU cable materials include power energy cables, communication cables, geo-exploration cables, automotive cables, industrial cables, and other special-purpose cables, such as spring wires, retractable wires, image and audio cables, and medical cables. In the automotive field, TPU is used to manufacture anti-lock braking system (ABS) cables, odometer cables, and automotive communication cables, which need to be hydrolysis-resistant, elastic and flexible, as well as good heat resistance. Geological exploration cables need to have good wear resistance and low temperature resistance.

In terms of electrical properties, TPU cable materials have low conductivity and are suitable for use as insulating materials in applications such as cable sheaths or cable connectors. The surface resistivity of TPU ranges from 10^13 to 10^15 Ω, while its volume resistivity is between 10^11 and 10^15 Ω·cm. The dielectric strength of TPU increases with the increase of hardness. The dielectric strength of polyether-based TPU is higher, which is 35 kV/mm at low hardness and rises to 38 kV/mm for higher hardness values. In addition, the dielectric constant and dielectric loss factor of TPU are also its important electrical properties, and these parameters are crucial for the electrical performance of cables.

With the improvement of environmental protection and safety requirements, the demand for halogen-free flame-retardant TPU cable materials is increasing. Halogen-free flame-retardant TPU not only has good flame retardant properties, but also does not produce toxic smoke when burning, which meets the requirements of environmental protection and health and safety. This material shows its unique advantages in the application of public places such as subway stations, large shopping malls, etc.

In general, TPU cable materials have become one of the important materials in the cable industry due to their excellent comprehensive properties. With the development of technology and changes in market demand, the application scope and performance of TPU cable materials will be further expanded and improved.
