This PP LGF40ASFR-integrates three critical performance pillars into a single pellet: 40% Long Glass Fiber for structural rigidity, a halogen-free Flame Retardant (UL94 V-0) package, and permanent Anti-Static/Conductive additives with Polypropylene resin.
√ 94V0-Flame resistance
√ good conductive electrical
√ Excellent Stiffness & Toughness Balance
Standard PP GF40 provides excellent mechanical strength, but in hazardous environments, strength alone is not enough. Standard polypropylene is flammable and electrically insulating, posing risks in electronics, mining, and automotive fuel systems. LFT-G® PP-LGF40ASFR is the "Total Safety" upgrade.
This advanced compound (Model: LGF40ASFR) integrates three critical performance pillars into a single pellet: 40% Long Glass Fiber for structural rigidity, a halogen-free Flame Retardant (UL94 V-0) package, and permanent Anti-Static/Conductive additives. It is designed to replace metal or expensive engineering plastics in applications where fire safety and static discharge control are mandatory.
√ UL94 V-0 Flammability: Self-extinguishing properties prevent fire propagation, essential for electrical enclosures and EV battery components.
√ High Strength Copolymer Base: Despite high additive loading, the long fibers maintain high impact strength and stiffness, outperforming short-fiber FR compounds.

Case Study: EV High-Voltage Distribution Box
The Safety Gap
An EV manufacturer needed a housing for a high-voltage junction box. Metal was too heavy and conductive (dangerous). Standard PP GF40 lacked flame retardancy and allowed static buildup, creating a fire risk in the event of a short circuit.
The LFT Bridge
LFT-G® PP-LGF40ASFR was deployed. The V-0 rating ensured any internal arc would self-extinguish. The conductive additives grounded stray static charges. The 40% long fibers provided the structural strength to bolt the box securely to the chassis.
The Certified Result:Passed stringent automotive flammability tests (UL94 V-0). Reduced weight by 30% vs. aluminum, with enhanced electrical safety for vehicle occupants.
Applications for Hazardous Environments
Mining Ventilation Fans
Operating in explosive dust. LFT-G® LGF40ASFR prevents static sparks (AS) and resists fire (FR), while the long fibers withstand high rotational forces.
ECU & Electronic Housings
Protects sensitive electronics. The material shields against EMI/static discharge and ensures that in the event of a short circuit, the housing will not catch fire.
Chemical Plant Conveyors
In volatile environments, static on moving parts is dangerous. LFT-G® LGF40ASFR rollers dissipate charge safely and resist chemical corrosion that would destroy metal.
People Also Ask
1. Can polypropylene be made flame retardant?
A: Yes. While native Polypropylene burns easily, LFT-G® PP-LGF40ASFR is modified with special halogen-free flame retardant additives. This allows it to achieve a UL94 V-0 rating, meaning it self-extinguishes within 10 seconds on a vertical specimen, making it safe for electrical applications.
2. Is conductive plastic fire resistant?
A: Not automatically. Conductivity and flame retardancy are separate properties. Standard conductive plastics can still burn. LFT-G® PP-LGF40ASFR is a specialized "Dual-Functional" grade that is engineered to be both conductive (to prevent sparks) and flame retardant (to stop fire), offering complete safety.
3. What is the difference between V0 and HB flammability?
A: HB (Horizontal Burn) is the lowest rating; the material burns slowly but does not self-extinguish effectively. V-0 (Vertical Burn) is the highest standard for plastics; the flame must self-extinguish within 10 seconds, and the material cannot drip flaming particles. LFT-G® PP-LGF40ASFR meets the V-0 standard.
