PA66 GF50 Density & Long Fiber Upgrades
The density of PA66-GF50 (50% glass fiber reinforced Polyamide 66) typically ranges from 1.56 g/cm³ to 1.61 g/cm³. For engineers calculating precise part weights, standard short-fiber PA66 GF50 is a common structural baseline. However, LFT-G® PA66 LGF50 offers a revolutionary performance upgrade. By utilizing 50% continuous long glass fibers, it builds a 3D internal skeleton that drastically multiplies impact toughness and tensile modulus to 16,000 MPa, all while maintaining the exact same lightweight 1.56 g/cm³ density profile.

Processing Guidelines for PA66 Long Glass Fiber
Pre-drying
100–110°C / 4–6h
Moisture < 0.10%
Injection
Melt Temp: 280–300°C
Low Shear Screw Speed
Tooling Settings
Mold Temp: 80–110°C
Generous Fan Gates
Engineered for Extreme Heavy-Duty Environments
Automotive Engine Compartments
High-vibration engine mounts, oil pans, and cooling system brackets must survive intense thermal radiation. PA66 LGF50 maintains structural integrity at 200°C+ continuous operating temperatures, utilizing its 16,000 MPa modulus to completely replace heavy cast metals.
Heavy-Duty Industrial Power Tools
Professional rotary hammers and high-torque gears face severe drop impacts. Capitalizing on a consistent 1.56 density for lightweight handling, the 35 kJ/m² impact toughness ensures the tool housing will never shatter under brutal industrial usage.
Industrial Load-Bearing Brackets
For scaffolding joints and heavy ventilation impellers, replacing rust-prone iron is a priority. The internal 3D continuous glass fiber network handles massive static loads and rotational stress, delivering extreme creep resistance in harsh environments.
