Name: China LFT-G® PP LGF40-NG04:Upgrade Of PP GF40 Factory, Manufacturers and Suppliers - LFT-G
Brand: LFT-G®
SKU: 284769018

Product Description & Features

LFT-G^® PP LGF40 -NG04 is a 40% long glass fiber reinforced polypropylene composite, supplied in pellet form for injection molding. This material combines the low density and chemical resistance of polypropylene with the high mechanical performance of long glass fibers.

Unlike standard short fiber (SGF) materials, the long fibers in LFT-PP form an internal "skeletal network" within the molded part. This structure is key to delivering superior performance in:

√ Structural Integrity: The fiber network provides exceptional strength and stiffness, allowing for the design of large, complex, load-bearing components.
√ Impact Energy Absorption: The long fibers effectively distribute impact forces, preventing catastrophic failure and offering high toughness, particularly in crash-relevant automotive parts.
√ Lightweighting: Offers a significant weight reduction (up to 40-50%) compared to steel or aluminum, and a 10-20% reduction versus PA6-GF composites, enhancing fuel efficiency and EV range.

Key Questions Answered

1. What is the benefit of using 40% glass fiber (PP LGF40) over 30%?

A: The jump from 30% to 40% long glass fiber provides a significant increase in stiffness (flexural modulus) and strength. This makes LFT PP LGF40 the prime candidate for demanding structural parts (like IP carriers or appliance chassis) where minimizing deflection under load is the primary design goal.

2. How does LFT PP LGF40 compare to die-cast aluminum?

A: LFT PP LGF40 offers a superior stiffness-to-weight ratio. While aluminum is stiffer, our composite is over 50% lighter. This allows for parts with similar structural performance to be made with significant weight savings. Additional benefits include part consolidation, total corrosion resistance, and lower manufacturing costs.

3. How does LFT PP LGF40 compare to LFT PA6 LGF40 (Nylon)?

A: PP LGF40 has two key advantages: cost and moisture. It is significantly more cost-effective than Nylon. Crucially, PP absorbs virtually zero moisture, meaning its mechanical properties and dimensions remain stable in wet environments (unlike PA6, which can soften and swell). PA6 LGF40's main advantage is a higher heat resistance (HDT >200°C vs. ~160°C for PP).
