Cable Compound For Electronic Appliances Industry Knowledge

What key performance indicators should be considered when selecting composite materials for electronic cables?

When selecting composite materials for electronic cables, the following key performance indicators are very important:

Electrical performance:
Dielectric Constant: affects the capacitance and signal transmission speed of the material.
Dielectric Loss: affects the efficiency of signal transmission, especially in high-frequency applications.
Insulation Resistance: ensures that current does not leak through the insulation layer, affecting the reliability of the cable.

Thermal performance:
Thermal Stability: the performance of the material in a high temperature environment, including thermal decomposition temperature and thermal expansion coefficient.
Heat Resistance: the long-term stability of the material at high temperatures to avoid performance degradation or failure in a hot environment.

Mechanical properties:
Flexibility: the performance of the material when bent and twisted, affecting the laying and service life of the cable.
Tensile Strength: the load-bearing capacity of the material during stretching, ensuring that it is not easy to break under mechanical stress.
Abrasion Resistance: the ability to resist external physical damage and extend the service life of the cable.

Chemical stability:
Corrosion Resistance: The material's resistance to chemicals and environmental conditions, especially in harsh environments.
Oil and Solvent Resistance: Resistance to common chemicals and solvents.

Flammability:
Flammability Rating: The material's burning characteristics when exposed to flames, ensuring safety.

Environmental adaptability:
UV Resistance: The material's resistance to ultraviolet rays, suitable for outdoor or high-intensity light environments.
Moisture Resistance: The material's resistance to moisture and water, preventing the degradation of insulation performance.

How do composite materials for electronic cables perform in terms of high temperature resistance and chemical corrosion resistance?

The performance of composite materials for electronic cables in terms of high temperature resistance and chemical corrosion resistance varies depending on the type of material. The following are the performances of several common composite materials for electronic cables in these aspects:

1. Polyurethane (PU)
High temperature resistance: Polyurethane has average high temperature resistance and can usually maintain its performance in the range of 80°C to 120°C. Performance degradation or deformation may occur above this temperature.
Chemical corrosion resistance: It has good resistance to most chemicals, but may be corroded in strong acids, strong alkalis and certain solvents.

2. Silicone
High temperature resistance: Silicone has excellent high temperature resistance and can usually withstand ambient temperatures of up to 200°C or even 250°C. Some special silicones can withstand higher temperatures.
Chemical corrosion resistance: Silicone has good resistance to most chemicals and solvents, but has limited resistance to strong acids and alkalis.

3. Fluoropolymer
High temperature resistance: Fluoropolymers have excellent high temperature resistance and can usually maintain stable performance in environments above 260°C.
Chemical corrosion resistance: Fluoropolymers have extremely high tolerance to almost all chemicals, including strong acids, strong bases and organic solvents.

4. Polytetrafluoroethylene (PTFE, Teflon)
High temperature resistance: PTFE has excellent high temperature resistance and can withstand ambient temperatures up to 260°C and remain stable for a long time.
Chemical corrosion resistance: PTFE has excellent corrosion resistance to almost all chemicals, including strong acids, strong bases and organic solvents.

5. Polyethylene (Polyethylene, PE)
High temperature resistance: Polyethylene has poor high temperature resistance and can generally be used in the range of 70°C to 90°C. Exceeding this temperature may cause deformation or melting.
Chemical corrosion resistance: It has good tolerance to most chemicals, but performs poorly in strong acid and strong base environments.

6. Polyvinyl chloride (PVC)
High temperature resistance: PVC has average high temperature resistance, usually working stably in an environment of 70°C to 85°C. It will soften and lose strength above this temperature.
Chemical corrosion resistance: PVC has good resistance to most chemicals, but may degrade in some strong acid and alkali environments.
