# Flame retardant thermoplastic polyurethane (TPU) of UL94 V-0 grade is a high-performance elastomer specially formulated for cable insulation and sheathing. It integrates exceptional fire safety, mechanical durability, and environmental resistance, making it ideal for power, communication, automotive, and industrial cables.
### Key Flame Retardant Performance – **UL94 V-0 Rating**: Achieves V-0 classification at 1.5mm thickness, ensuring **self-extinguishment within 5 seconds** and no dripping of flaming particles that ignite combustible materials. – **Compliance with Cable Standards**: Passes **IEC 60332-1-2** (single vertical burning) and **UL 1581 VW-1** (vertical wire flame test), meeting global fire safety requirements for cables. – **Halogen-Free & Low Smoke**: Eco-friendly formulation (no halogens) emits **low smoke and low toxicity** during combustion, critical for public spaces, data centers, and EV applications.
### Core Material Advantages 1. **Superior Mechanical Properties** – High tensile strength (≥15–30 MPa) and tear resistance (≥40 N), resisting abrasion, impact, and mechanical stress during installation and use. – Excellent flexibility (elongation at break: 450%–550%) over a wide temperature range (-50°C to 125°C), maintaining elasticity in extreme cold or heat. 2. **Outstanding Environmental Resistance** – **Hydrolysis & Chemical Resistance**: Withstands 1,000–2,000 hours of hydrolysis (85°C/85% RH) and resists oils, acids, alkalis, and UV radiation, extending cable service life. – **Mold & Mildew Resistance**: Complies with military standards (GJB 150.10), suitable for humid and harsh environments. 3. **Processing & Application Versatility** – Suitable for **extrusion and injection molding**, enabling efficient production of cable jackets and insulation layers. – Customizable hardness (Shore A 70–95) and colors, supporting diverse cable designs and marking requirements.
### Typical Applications – **EV Charging Cables**: High voltage resistance, flame safety, and durability for electric vehicle charging systems. – **Communication & Data Cables**: Low smoke, halogen-free, and high electrical insulation for data centers and telecom networks. – **Automotive Cables**: Resists oil, heat, and vibration for engine wiring and in-vehicle communication. – **Industrial & Marine Cables**: Withstands harsh chemicals, UV, and extreme temperatures for industrial machinery and marine equipment.
### Compliance & Certifications – **UL94 V-0** (1.5mm), **RoHS**, **REACH**, **IEC 60332**, **UL 1581**. – Halogen-free, low smoke, and low toxicity, aligning with global environmental and safety regulations. This V-0 grade flame retardant TPU balances **fire safety, durability, and sustainability**, serving as a reliable solution for high-performance cables in safety-critical applications.
