Cable Compound: TPU Pellet Material

What is TPU Material?

TPU (Thermoplastic Polyurethane) is an advanced polymer material that falls between elastomeric plastics and rubber. It can be categorized into ester-based and ether-based types. TPU materials can be produced for wire and cable applications using various polymer processing techniques, such as injection molding and extrusion. They possess characteristics like high and low temperature resistance, flame retardancy, abrasion resistance, and oil resistance. TPU is widely used in the manufacture of cables for electric vehicles, charging stations, marine floating cables, equipment, wire plugs, and medical cables.

Angreen is a professional TPU material manufacturer and thermoplastic polyurethane supplier in China. We are one of the few TPU manufacturers on the market capable of providing halogen-free flame-retardant ether-based TPU materials that meet VW-1 or IEC60332 flame retardancy testing requirements. Our modified TPU (TPU composites/thermoplastic polyurethane) and TPU cable sheath material technologies are at the forefront of large-scale industrial applications worldwide. Our thermoplastic polyurethane has achieved UL94 -V0 certification.

At low temperatures, TPU remains soft, while PVC hardens.

At room temperature, PVC has a noticeable plastic odor, whereas TPU is virtually odorless.

TPU is recyclable, making it an environmentally friendly material.

Application Of TPU materials in cable Field

TPU cable compound, which refers to thermoplastic polyurethane cable materials, has found widespread applications in the cable industry due to its excellent physical and chemical properties. TPU cable materials can be utilized in power energy cables, communication cables, geological exploration cables, automotive cables, industrial cables, and other special-purpose cables (such as spring wires, retractable cables, image and audio cables, and medical cables).

In the automotive sector, TPU is used to manufacture cables for anti-lock braking systems (ABS), speedometer cables, and automotive communication cables, all of which require hydrolysis resistance, elasticity, flexibility, and good heat resistance.

Regarding electrical performance, TPU cable materials exhibit low conductivity, making them suitable as insulation materials in applications like cable sheaths or connectors. The surface resistivity of TPU ranges from 10^13 to 10^15 Ω, while the volume resistivity is between 10^11 and 10^15 Ω·cm. The dielectric strength of TPU increases with hardness; for ether-based TPU, it reaches about 35 kV/mm at lower hardness and can rise to 38 kV/mm at higher hardness. Additionally, the dielectric constant and dielectric loss factor of TPU are important electrical properties that are critical to the electrical performance of cables.

Thermoplastic Polyurethane Sold by Processing Method

Thermoplastic plastics can be reshaped and are typically produced using various polymer processing technologies, including injection molding and extrusion. As a leading manufacturer and supplier of TPU composites and thermoplastic polyurethane materials worldwide, Angreen offers high-quality extruded TPU cable sheaths and injection-molded TPU in the TPU manufacturer market.

With the increasing emphasis on environmental and safety requirements, the demand for halogen-free flame-retardant TPU cable materials is on the rise. Halogen-free flame-retardant TPU not only demonstrates excellent flame-retardant properties but also does not emit toxic fumes when burned, meeting environmental and health safety standards. This material is particularly advantageous in public spaces such as subway stations and large shopping malls. Overall, TPU cable materials have become one of the essential materials in the cable industry due to their outstanding comprehensive performance. With advancements in technology and changes in market demand, the application range and performance of TPU cable materials will continue to expand and improve.
