White PET coated wires have advantages in insulation, temperature resistance, and corrosion resistance, but their disadvantages such as hydrolysis resistance, flexibility, cost, and processing difficulty need to be weighed according to specific application scenarios. The disadvantages of white PET coated wires mainly include the following:

1. Poor hydrolysis resistance

PET materials are prone to hydrolysis under high temperature and alkaline conditions, resulting in reduced insulation performance and possible leakage or short circuit risks.

2. Weak tolerance to strong alkali and certain chemicals

Long-term contact with strong alkali or specific chemical solvents may cause the coating to dissolve or corrode, affecting the service life of the wire.

3. Low thermal deformation temperature

Under continuous high temperature environment, PET coating may soften and deform, reduce insulation strength, and limit its application in extreme high temperature scenarios.

4. Insufficient flexibility

Compared with materials such as PVC, PET coating has poor bending resistance, and frequent bending is prone to cracking, which is not suitable for scenes that require frequent movement.

5. High cost

PET material itself is more expensive than common insulating materials such as PVC, and it is difficult to process, resulting in a significant increase in overall cost.

6. Low-temperature brittleness

In extremely cold environments (such as below -70°C), PET materials may become brittle, increasing the risk of breakage and requiring additional protective measures.

7. Prone to static electricity

PET materials are prone to carry static electricity, which may absorb dust or cause static electricity discharge, and require anti-static treatment.

8. Difficult processing

PET coatings are sensitive to temperature, and the temperature and process parameters must be strictly controlled during processing, otherwise the coating may melt or deform.

9. Color limitations

White coatings are easy to get dirty, and the cleaning and maintenance costs are high, and may not meet aesthetic requirements in specific application scenarios.
