LFT-G® PP-LGF30: Precision Density & Lightweighting Data

LFT-G® PP-LGF30: Precision Density & Lightweighting Data

Details
For structural engineers executing mass-reduction projects, precise material weight calculation is critical. The density of PP LGF30 is typically 1.12 g/cm³ (or 1120 kg/m³), acting as an ultra-lightweight foundation for metal substitution. Depending on specific co-polymer or homo-polymer matrices, our LFT-G® engineering grades reliably maintain a narrow tolerance range of 1.11 ± 0.03 g/cm³. This exceptionally low specific gravity, combined with a continuous long-glass-fiber skeleton, allows manufacturers to slash component weight without compromising severe impact resistance.

Density Comparison: Why PP LGF30 Dominates Lightweighting

Modern electric vehicles (EVs) and aerospace components can no longer afford the heavy burden of die-cast metals. At just 1.12 g/cm³, LFT-G® PP LGF30 offers a staggering weight reduction advantage while utilizing its 30% long-fiber internal skeleton to match the structural rigidity of traditional alloys. To demonstrate the sheer mass-saving potential for your next injection molding project, review the exact specific gravity comparison chart below against standard engineering materials.

Transforming Industries via Mass Reduction

EV Battery Trays lightweighted with PP LGF30

EV Battery Trays & Enclosures

Every ounce saved on an electric vehicle directly increases driving range. By leveraging the 1.12 g/cm³ specific gravity of our 30% long fiber composite, automotive OEMs can replace extremely heavy steel battery enclosures while perfectly retaining the 7,000 MPa stiffness required to pass stringent crash-test standards.

UAV and commercial drone frames molded with PP LGF

UAV & Commercial Drone Frames

Commercial aerospace applications require absolute material optimization to maximize battery life. This ultra-lightweight thermoplastic radically lowers the payload threshold of drone arms and landing gears, offering superior vibration damping capabilities that traditional aluminum structures completely lack.

Automotive interior door modules using lightweight PP composite

Automotive Door Modules

Combining structural integrity with mass efficiency, inner door panels molded from PP LGF30 completely negate the need for secondary steel reinforcements. The integrated long-fiber matrix prevents thermal warpage under intense cabin heat, ensuring precise dimensional tolerances for interior assembly.

Frequently Asked Questions (FAQ)

Q1: How much lighter is PP LGF30 compared to aluminum?

A: Die-cast aluminum typically has a density of 2.70 g/cm³, whereas our LGF30 compound sits at 1.12 g/cm³. This equates to a staggering 60% mass reduction for identical component volumes, massively lowering transport costs.

Q2: Does the low density compromise its mechanical stiffness?

A: No. Because the 30% long glass fibers create a continuous internal skeleton during molding, the material retains a massive 7,000 MPa flexural modulus, providing metal-like rigidity despite its ultra-low weight.

Q3: Do you offer free density and material testing analysis?

A: Yes. As the direct factory source, our engineering team provides complimentary structural analysis and offers a 25KG MOQ trial sample to physically validate your lightweighting ROI.
