PA Flame-Retardant Corrugated Pipe

Five Core Advantages
1. UL94 V0 Flame Retardancy: Self-Extinguishing
It has passed the UL94 vertical burning test, demonstrating a burn time of ≤10 seconds with no flaming drips capable of igniting cotton. The flame-retardant system is free from restricted substances such as red phosphorus and halogens, thereby complying with environmental protection standards.
2. Oil and Chemical Resistance: Suitable for Harsh Conditions
It exhibits excellent resistance to mineral oils, diesel, gasoline, lubricants, and weak acids and bases; furthermore, its flame-retardant performance remains stable even after prolonged immersion in oil contaminants.
3. Wide Temperature Stability: Covering -40°C to 120°C
It does not become brittle or crack at low temperatures (having passed the -40°C low-temperature impact test) and does not soften or deform at high temperatures; its flame-retardant properties remain undiminished even under extreme thermal conditions.
4. High Mechanical Strength: Compression and Tear Resistant
The annular corrugated structure provides superior ring stiffness and impact resistance, allowing the tubing to quickly recover its shape after compression, thereby protecting internal cables from damage. Its tensile strength significantly exceeds that of standard PE/PP corrugated tubing.
5. Excellent Flexibility: Small Bending Radius
It is highly flexible and retains its bent shape without springing back; the minimum bending radius is only 3 to 5 times its inner diameter, facilitating easy cable routing in confined spaces (e.g., within automotive door panels or robotic joints).

Typical Application Scenarios
New Energy Vehicles: High-voltage wiring harnesses within battery packs, motor controller harnesses, and charging port connection cables (featuring UL94 V0 flame retardancy, oil resistance, and vibration resistance). Rail Transit: Underfloor wiring in high-speed train carriages, subway bogie cabling, signal system protective conduits.
Industrial Power Distribution: CNC machine tool control cabinets, robotic cable drag chain systems, internal cabling for laser equipment (flame-retardant + fatigue-resistant).
Automotive Engine Compartments: ABS sensor harnesses, oxygen sensor harnesses, engine peripheral cabling (high-temperature resistant + oil-resistant + flame-retardant).
Energy Storage Systems: Inter-module connection cables for battery energy storage, protective conduits for BMS sampling lines (UL94 V0 rated, salt-spray resistant).

Production & Quality Control Capabilities
Molding Process: Fully automated extrusion lines dedicated to flame-retardant materials + inline laser diameter measurement; internal diameter range: 6mm–65mm (closed type), 10mm–50mm (split type).
Flame Retardancy Testing: UL94 vertical burning tests (V0/V2 rating verification) are conducted on every production batch, with corresponding test videos and reports archived.
Other Testing Items: Low-temperature impact resistance at -40°C (no cracking), dielectric strength (no breakdown at 1000V/1 min), ring stiffness testing.
Customization Services: Flame retardancy ratings (V0/V2), split/closed structural designs, UV resistance (black UV-stabilized), special colors (e.g., high-voltage warning orange).
