Cable trunking is an essential component in modern electrical and data systems. It provides a protective pathway for wires and cables, ensuring safety, organization, and long-term reliability. From homes and offices to factories and data centers, cable trunking is used wherever wires need to be organized, hidden, and protected.
Thanks to plastic extrusion technology, cable trunking can be manufactured in a wide range of materials—each offering unique benefits in terms of durability, flame resistance, aesthetics, and cost.
As a professional plastic extrusion cable trunking factory with 20 years of manufacturing experience, SW specializes in PVC cable trunking as well as other plastic trunking materials. In this blog, we’ll explore the most common materials used for extruded cable trunking, compare their properties, and provide guidance on choosing the right type for your project.
Why Material Choice Matters for Cable Trunking
The performance of cable trunking depends heavily on the material used. Key factors include:
Electrical insulation – Prevents short circuits and protects users.
Flame resistance – Critical for fire safety.
Impact strength – Important in industrial and outdoor environments.
Heat resistance – Ensures stability under high cable loads.
Aesthetics – Especially important in offices, retail, and residential spaces.
Cost – Must balance budget with performance.
By selecting the right material, engineers and contractors can maximize safety, reduce maintenance, and extend the life of electrical systems.
Common Cable Trunking Materials
1 PVC Cable Trunking
Overview:
PVC is the most widely used material for extruded cable trunking. It combines affordability, durability, and good flame resistance.
Advantages:
Cost-effective: One of the cheapest trunking materials.
Flame retardant: Self-extinguishing properties reduce fire risk.
Excellent insulation: Prevents electrical leakage.
Corrosion resistant: Does not rust or degrade easily.
Variety of finishes: Available in white, gray, or custom colors.
Disadvantages:
Heat limitations: Softens at higher temperatures (>60°C).
Environmental impact: Not as eco-friendly as some alternatives.
Applications:
Residential electrical wiring
Office cable management
General indoor applications
SW specializes in PVC cable trunking extrusion, offering custom sizes, flame-retardant grades, and OEM solutions for global clients. Learn more about SW PVC cable trunking factory.
2 ABS Cable Trunking
Overview:
ABS is a tough, impact-resistant plastic often used in higher-end applications.
Advantages:
High impact strength: Resistant to physical damage.
Good surface finish: Can be made with glossy or textured surfaces.
Moderate heat resistance: Performs better than PVC under heat.
Disadvantages:
Higher cost than PVC.
Less flame resistance compared to specialized PVC grades.
Applications:
Industrial cable protection
Areas prone to mechanical impact
Data centers requiring stronger trunking
3 PP Cable Trunking
Overview:
Polypropylene is lightweight, chemically resistant, and flexible.
Advantages:
Lightweight and easy to install
High chemical resistance
Good fatigue resistance (withstands repeated stress)
Affordable alternative to ABS
Disadvantages:
Lower flame resistance unless specially treated
Less rigid than PVC or ABS
Applications:
Industrial plants exposed to chemicals
Lightweight, budget-friendly projects
Temporary wiring installations
4 PE Cable Trunking
Overview:
Polyethylene is known for its toughness and weather resistance.
Advantages:
Excellent outdoor performance
Good chemical resistance
Impact resistant even at low temperatures
Moisture resistant
Disadvantages:
Lower flame resistance without additives
Less aesthetic finish compared to PVC or ABS
Applications:
Outdoor wiring protection
Agricultural installations
Harsh environments with moisture exposure
5 PC Cable Trunking
Overview:
Polycarbonate is a premium material with exceptional mechanical and thermal properties.
Advantages:
High heat resistance – ideal for heavy electrical loads
Unbreakable strength – impact resistance superior to ABS
Excellent flame retardancy
Transparent options available
Disadvantages:
Significantly more expensive
Heavier than other plastics
Applications:
High-performance electrical systems
Industrial and commercial buildings
Environments with strict fire safety standards
