In power cord production, material selection directly affects electrical safety, mechanical strength, and service life. PE, PP, and ABS are the three most commonly used materials. PE and PP are primarily used for wire insulation and sheathing, while ABS is mainly used for plugs and housings.
I. PE (Polyethylene)
PE is a classic wire insulation material with excellent electrical insulation, good flexibility, low-temperature resistance, and extremely low water absorption. It is suitable for long-term use from -40°C to 80°C, making it ideal for power cord inner insulation. Standard PE is non-flame-retardant (oxygen index 17–18) and requires flame-retardant modification (e.g., with magnesium hydroxide or aluminum hydroxide) to meet safety standards. PE is used for insulation layers in power cords, electronic wires, and data cables, and can also serve as lightweight cable sheathing. It is generally not used for plug housings.
II. PP (Polypropylene)
PP outperforms PE in heat resistance and mechanical strength. Modified grades achieve long-term operating temperatures of 100°C to 105°C, with excellent flex resistance, fatigue resistance, and chemical stability. PP is well-suited for electronic wires, wiring harnesses, and medium-to-high-temperature power cords requiring higher heat resistance and durability. Like PE, PP is primarily used for wire applications. Its rigidity and impact strength are lower than ABS, and its high mold shrinkage makes it unsuitable for plug housings.
III. ABS
ABS is an engineering plastic specifically for power cord plugs and housings. It combines rigidity, impact resistance, dimensional stability, and excellent surface gloss, with superior injection molding processability. Standard ABS is flammable (oxygen index approximately 18), so flame-retardant ABS meeting UL 94 V-0 or V-2 ratings is required for power cord applications. ABS is not suitable for wire insulation and is used exclusively for external plastic components.
IV. Selection Recommendations
PE: For insulation layers in power cords, electronic wires, and data cables requiring high insulation performance and flexibility. Flame-retardant modified PE must be used.
PP: For electronic wires, wiring harnesses, and medium-to-high-temperature power cords demanding higher heat resistance and flex resistance.
Flame-Retardant ABS: For plugs, adapter housings, cable clips, and other structural components. Select ABS meeting UL 94 flame-retardant ratings.
Proper material selection ensures optimal safety, durability, and appearance for power cords.
