LFT-G® 30% Long glass fiber PP (Copo)
What is PP-LGF30FR?
A high-performance flame-retardant engineering plastic designed for industrial structural part manufacturing, PP-LGF30FR is 30% long glass fiber (LGF) reinforced polypropylene (PP) with integrated flame-retardant (FR) functionality-engineered to meet the strict strength, safety, and durability demands of global automotive, electronics, and machinery sectors.
Key Performance Advantages
Superior Mechanical Strength & Durability
30% long glass fiber reinforcement delivers 3x higher notched impact strength and 40% better creep resistance than short-fiber PP alternatives, ensuring long-lasting performance for load-bearing structural parts.
Reliable Flame Retardancy
Integrated flame-retardant formula meets strict UL94 V-0 fire safety standards, ideal for high-risk applications like automotive engine bay components and electronic device housings requiring EU market compliance.
Exceptional Dimensional Stability
Low water absorption and minimal warpage guarantee precise part molding, reducing post-processing costs and avoiding assembly issues caused by material deformation.
Cost-Effective & Process-Friendly Molding
Compatible with standard injection molding equipment, featuring smooth melt flow and reducing production scrap rates, lowering overall manufacturing costs for mass production.

FAQ
Q: Which applications benefit most from PP-LGF30FR?
A: This combo excels in scenarios requiring both safety and structural reliability: 1. New energy vehicle battery pack brackets; 2. Electrical equipment enclosures ; 3. Industrial control cabinet internal supports.
Q: Can PP-LGF30FR be customized for specific color or fiber content requirements?
A: Yes. We offer two key customizations: 1. Color matching (per Pantone/RAL codes, suitable for brand-unified component production); 2. Fiber content adjustment (20%-60% LGF, tailored to balance cost, strength, and flame retardancy). All customized batches undergo the same performance testing as standard grades.
Q: What's the key difference between PP-LGF30FR and general grade PP-LGF30?
A: General-grade PP-LGF30 offers long-fiber-reinforced strength/rigidity, but lacks flame retardancy. In contrast, PP-LGF30FR retains the reinforced performance of PP-LGF30, along with flame-retardant properties, making it suitable for fire-required industrial/electronics/automotive scenarios.
