The Ultimate Moisture-Proof Structural Nylon
Traditional polyamides like PA6 and PA66 suffer a fatal flaw in fluid environments: they absorb moisture rapidly, leading to severe swelling and a catastrophic drop in mechanical stiffness. LFT-G® PA12-NA-LGF50 completely resolves this engineering nightmare. By utilizing the inherently moisture-resistant Nylon 12 matrix infused with a 50% long glass fiber internal skeleton, this composite maintains its exceptional 12,000 MPa flexural modulus and exact molecular dimensions even after years of continuous submersion or high-humidity exposure.

Processing Guidelines for Nylon 12 LGF
Pre-drying
80–100°C / 4–6h
Ensure Moisture < 0.1%
Injection
Melt Temp: 240–280°C
Optimize for LGF Length
Tooling Settings
Mold Temp: 60–100°C
Generous Gate Size Required
Engineered for Critical Fluid & Precision Mechanics
Smart Water Meters & Fluid Valves
Precision metering equipment requires gears and housings that will never swell, even after a decade of continuous submersion. PA12 LGF50 provides unmatched dimensional stability, ensuring internal rotating components never seize due to moisture expansion, completely outperforming standard PA66 alternatives.
High-Pressure Pneumatic & Hydraulic Connectors
Industrial fluid lines operate under extreme hydrostatic pressure and are constantly exposed to aggressive hydraulic oils. The robust long fiber skeleton within our Nylon 12 matrix grants phenomenal burst strength and fatigue endurance, while inherently resisting chemical degradation from synthetic lubricants.
Medical Load-Bearing Components
Advanced hospital beds and surgical robotic arms rely on absolutely flawless mechanical precision. PA12 LGF50 delivers a metal-like 12,000 MPa modulus alongside natural self-lubricating properties, ensuring smooth, silent, and rigid performance for high-end medical rail mechanisms without requiring greasy maintenance.
