What are the main causes of silicone wire aging?

Although silicone wire has strong aging resistance, long-term use in harsh environments will still cause aging and performance degradation.

1. Long-term high temperature baking: working above the rated      temperature for a long time will accelerate the aging and hardening of      silicone insulation.

2. Ultraviolet and ozone erosion: outdoor long-term exposure will      cause the surface of the wire to crack and peel.

3. Mechanical friction and extrusion: long-term pulling, bending      and friction damage the insulation protective layer.

4. Chemical corrosion: contact with acid, alkali, oil and organic      solvents will corrode the silicone layer.

5. Overload and high voltage breakdown: long-term overcurrent      operation leads to internal heating and insulation damage.

Regular maintenance, avoiding overlimit use, and doing a good job of protection can effectively delay aging and extend service life.
