Common types of conductive TPU

There are several types of conductive TPU:

1. Carbon black filled conductive TPU:
Principle: Add carbon black as a conductive filler to the TPU matrix. Carbon black has a high specific surface area and good conductivity, forming a conductive network in TPU, giving the material conductivity.
Performance characteristics: The color is usually black, with good conductivity and processing performance, and can be used for products such as wires, pipes, watch straps, shoe materials, casters, rubber packaging, electronic appliances, etc.
Advantages: Carbon black has a relatively low cost and a wide range of sources, which can to some extent reduce the cost of conductive TPU; Meanwhile, the addition of carbon black has little effect on the mechanical properties of TPU, and the material can still maintain good elasticity, wear resistance, and tear resistance.

2. Carbon fiber filled conductive TPU:
Carbon fiber conductive grade TPU has many significant characteristics. Firstly, its stable conductivity enables it to reliably function in areas that require conductivity. For example, in the manufacturing of electronic and electrical components, stable current transmission can be ensured to avoid static electricity accumulation and damage to electronic components. It has good toughness and can withstand large external forces without easily breaking, which is very important in some application scenarios that require high material strength, such as sports equipment, automotive components, etc. High rigidity ensures that the material is not easily deformed during use, maintaining the shape and structural stability of the product.
Carbon fiber conductive grade TPU also has excellent wear resistance, and among all organic materials, TPU is one of the more wear-resistant materials. At the same time, it also has the advantages of good resilience, good sealing, low compression deformation, and strong creep resistance. Excellent performance in oil and solvent resistance, able to maintain stable performance in environments exposed to various oily and solvent based substances. In addition, TPU is an environmentally friendly material with good skin affinity, which can be used in the production of various equipment to ensure the safety and comfort of users. Its hardness range is wide, and different hardness products can be obtained by changing the ratio of each reaction component to meet different application needs. High mechanical strength, excellent load-bearing capacity, impact resistance, and shock absorption performance of the product. Even in low-temperature environments, it maintains good elasticity, flexibility, and other physical properties. Good processing performance, can be processed using common thermoplastic material processing methods such as injection molding, extrusion, rolling, etc., and can also be processed together with certain polymer materials to obtain polymer alloys with complementary properties. Good recyclability, in line with the requirements of sustainable development.
3. Metal fiber filled conductive TPU:
Principle: Mix metal fibers (such as stainless steel fibers, copper fibers, etc.) with TPU, and the metal fibers come into contact with each other to form a conductive path, thereby making TPU conductive.
Performance characteristics: Good conductivity, high strength and stiffness, but the flexibility of the material may be affected to some extent.
Advantages: Compared with carbon black filled conductive TPU, metal fiber filled conductive TPU has higher conductivity stability and is less susceptible to environmental factors; And in some situations where high conductivity is required, such as electromagnetic shielding, anti-static and other fields, it has better application effects.
4. Carbon nanotube filled conductive TPU:
Principle: By utilizing the excellent conductivity of carbon nanotubes, they are added to TPU, and the carbon nanotubes are uniformly dispersed and interconnected in the TPU matrix to form a conductive network.
Performance characteristics: It has high conductivity and good mechanical properties, as well as excellent thermal and chemical stability.
Advantages: The addition of relatively small amounts of carbon nanotubes can achieve good conductivity and maintain the original properties of TPU; In addition, the small size of carbon nanotubes does not have a significant impact on the appearance and processing performance of the material.
