How do l choose the right wire?

In wire harness customization, selecting the right outer jacket material significantly affects product durability, safety, and cost efficiency. With common options like PVC, PE, TPU, and Silicone, customers often face confusion during the selection process.

As a manufacturer specializing in custom cable assemblies, Era WingShing has summarized years of production experience to help you quickly choose the right material for different application scenarios.

✅ PVC (Polyvinyl Chloride) – Cost-Effective and Practical

Pros: Low cost, good formability, excellent flame resistance.

Best for: Household appliances, computer peripheral cables, indoor lighting.

Note: Not suitable for high-temperature or outdoor use due to limited heat and UV resistance.

✅ PE (Polyethylene) – Excellent Cold Resistance

Pros: Moderate flexibility, great insulation, performs well in low temperatures.

Best for: Refrigeration equipment, low-temperature wiring, power tools.

Note: Less heat-resistant and more brittle; suitable for static installations.

✅ TPU (Thermoplastic Polyurethane) – Durable and Flexible

Pros: High flexibility, oil resistance, wear resistance, and great for repetitive motion.

Best for: Industrial automation, robots, medical equipment.

Note: Higher cost, not ideal for extreme heat environments.

✅ Silicone – High & Low Temperature Champion

Pros: Excellent heat/cold resistance, very flexible, anti-aging, and eco-friendly.

Best for: High-temp appliances, outdoor lighting, EVs, and advanced medical harnesses.

Note: Higher production costs and stricter processing requirements.
