LFT-G® PP LGF30 | The High-Performance Upgrade to PP GF30

Product Description & Features

LFT-G PP LGF30 material-the performance upgrade of PP GF30 short fiber LFT-G^® PP LGF30 -NG03 is a 30% long glass fiber reinforced polypropylene composite. Engineers searching for standard 'PP GF30' value its good stiffness-to-cost ratio. LFT-G^® PP LGF30 is the professional upgrade, designed to solve the common failures of short-fiber materials: poor impact strength and long-term creep.

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:

√ Balanced Performance: The ideal "workhorse" grade, offering an excellent combination of high stiffness and exceptional toughness.
√ Superior Impact Strength: The long-fiber network arrests crack propagation, providing 2-3 times the impact resistance of SGF PP GF30, especially at low temperatures.
√ Long-Term Creep Resistance: Maintains its shape under constant load and heat, making it reliable for true structural applications where SGF would fail.

Applications for Balanced-Performance PP LFT

Durable Power Tool Housing

Power Tool Housings

Provides the perfect blend of high rigidity to protect internal components and exceptional impact resistance to survive job-site drops and abuse, replacing standard PA6 GF30.

Automotive Door Module Carrier made from LFT PP LGF30

Automotive Door Modules

A lightweight solution for large carriers. LFT PP LGF30 offers the stiffness to support window regulators and speakers, plus the high impact strength needed for side-impact safety.

Structural support frame for an industrial water pump

Industrial Pump Housings

An excellent replacement for cast metal. LFT PP LGF30 provides long-term dimensional stability, high creep resistance, and complete immunity to corrosion from water and chemicals.

Key Questions Answered

1. Why should I use LFT PP LGF30 instead of a standard PP GF30?

A: The key difference is long-term performance and toughness. The long-fiber network in LFT PP LGF30 provides far superior impact strength (especially in cold) and creep resistance. This means your part won't sag under load or crack when dropped, which are common failure points for short-fiber (SGF) PP GF30.

2. What is the difference between PP LGF30 and PP LGF40?

A: The choice depends on your primary goal. LFT PP LGF30 (30% fiber) is the "workhorse" grade, offering the best balance of high impact strength and good stiffness. LFT PP LGF40 (40% fiber) is a step up in stiffness and is chosen when minimizing deflection is the most critical design requirement, though it trades away some impact toughness.

3. How does LFT PP LGF30 compare to LFT PA6 LGF30 (Nylon)?

A: PP LGF30 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 LGF30's main advantage is its higher heat resistance (HDT >200°C).
