Flame-retardant polypropylene corrugated pipe is a high-performance cable protection pipe made of modified polypropylene (PP) as the base material and added with flame retardants and stabilizers. The product surface is a corrugated structure with excellent flexibility, mechanical strength and flame retardant properties. It is widely used in the protection of wires and cables in the fields of power, communication, rail transit, automotive wiring harnesses, electromechanical equipment, etc.
2. Product Features
Excellent flame retardant performance: meets UL94 V-0 or V-2 flame retardant grade, good self-extinguishing property, and extinguishes immediately when away from fire.
Reliable material: modified polypropylene is used, with good chemical stability, heat resistance and mechanical strength.
Flexible structure: The corrugated structure is flexible, bendable, resistant to pulling and not easy to break.
Easy installation: It can be used with special connectors (nylon buckles, quick connectors) for easy threading and maintenance.
Environmentally friendly and halogen-free: It does not contain halogen, burns without toxic gases, and is suitable for application scenarios with high environmental protection requirements.
Anti-UV/aging resistance: Suitable for long-term use indoors and outdoors, with excellent weather resistance.
