√ Excellent Stiffness & Toughness Balance
LFT-G® PP LGF30-FR | The Fire-Safe Structural Upgrade for PP GF30
LFT-G® 30% Long glass fiber PP (Copo) - Flame Resistant
Standard PP GF30 is the industry's "workhorse" material for structural parts, but it has a critical weakness: it burns easily. In today's electronics and EV sectors, this flammability is unacceptable. LFT-G® PP-LGF30FR is the engineered answer to this safety challenge.
This specialized grade (Model: NG03FR) balances three critical properties: structural rigidity from 30% Long Glass Fiber, impact durability from a Copolymer PP matrix, and certified fire safety via a halogen-free Flame Retardant (V-0) system. It offers a lightweight, cost-effective alternative to FR-Nylons, ensuring parts remain dimensionally stable under load while preventing fire propagation.
√ UL94 V-0 Safety: Achieves the highest flammability rating for plastics, self-extinguishing within seconds to protect sensitive electronics and batteries.
√ Balanced Structural Strength: The 30% LGF content provides the optimal mix of stiffness and weight, perfect for medium-to-large housings that must resist warping.
√ Electrical Insulation: Maintains high CTI (Comparative Tracking Index) values, preventing electrical arcing and short circuits in high-voltage environments.
The "Golden Triangle" of Performance
Most FR materials sacrifice toughness for safety. LFT-G® PP-LGF30FR breaks this rule by expanding performance in all three critical directions.

OUTDOOR
Solar Inverter Housings
Must resist internal heat and outdoor elements. LFT PP LGF30FR is weatherable, fire-retardant, and tough enough to protect sensitive inverter electronics.
STRUCTURAL
Switchgear Frames
Provides the rigid backbone for industrial circuit breakers. The LGF structure maintains precise component alignment, while the FR package ensures safety compliance.
People Also Ask (Google PAA)
1. Is glass filled polypropylene flammable?
A: Yes, standard glass-filled PP (like PP GF30) burns easily and is rated UL94 HB (Horizontal Burn). For applications requiring safety, you must use a specialized Flame Retardant grade like LFT-G® PP-LGF30FR, which is formulated to self-extinguish and meet the stricter UL94 V-0 standard.
2. What is the difference between FR PP and Standard PP?
A: Standard PP acts as a fuel source in a fire. FR (Flame Retardant) PP contains additives that chemically disrupt combustion. When exposed to flame, LFT-G® PP-LGF30FR forms a char layer that cuts off oxygen, stopping the fire from spreading, which is critical for compliance in electronics and automotive sectors.
3. Can FR PP replace FR Nylon (PA6)?
A: In many cases, yes. While FR Nylon has higher heat resistance, it absorbs moisture which can affect electrical properties. LFT-G® FR-PP absorbs zero moisture, ensuring stable electrical insulation (CTI), is lighter, and often more cost-effective. It is an excellent replacement for applications with operating temperatures below 120°C.
