The Gateway to Metal Replacement: Supreme Flowability Meets Structural Rigidity
When engineering plastic components, heavily loaded composites (such as 50% or 60% fiber) provide maximum stiffness but often sacrifice melt flowability and surface aesthetics. The LFT-G® PA6 LGF20 composite strategically targets the "sweet spot" for visible structural components. By reinforcing the highly resilient Polyamide 6 matrix with exactly 20% continuous long glass fibers, we create an internal 3D load-bearing skeletal network that achieves an impressive 8,885 MPa tensile modulus. Because the fiber loading is kept at a moderate 20%, the polymer maintains supreme flowability during the injection molding process. This allows the resin to perfectly fill highly complex, thin-walled molds without suffering from the dreaded "floating fiber" surface defects. Engineers are left with a component that possesses immense structural fatigue resistance and an ultra-low molding shrinkage of just 0.1%, all wrapped in a flawless, consumer-ready surface finish.

High-Aesthetic Structural Applications
Visible Automotive Engine Beauty Covers
Unlike functional under-hood components, engine beauty covers and NVH acoustic shields demand an exceptionally smooth surface finish alongside high heat resistance. The supreme melt fluidity of PA6 LGF20 prevents unsightly floating glass fibers on the part's exterior, while the 208°C HDT easily withstands the radiant thermal stress of the combustion engine compartment.
Industrial Power Tool Enclosures
Professional power drills and rotary hammers feature complex mold geometries with numerous internal reinforcing ribs and screw bosses. The LGF20 composite effortlessly flows into these intricate micro-features during injection. Once cooled, the internal continuous fiber network grants the tool casing extreme resistance to fatigue and drop-impacts (26.5 KJ/m² Izod impact), protecting the internal motor during harsh construction site usage.
