40% Long Carbon Fiber Reinforced Semi-Aromatic Nylon (Semi-Aromatic PA LCF40)

Product Overview

Semi-Aromatic PA LCF40 is a high-strength engineering plastic based on aromatic polyamide and reinforced with 40% long carbon fiber. Compared to aliphatic nylons, semi-aromatic nylons offer lower moisture absorption, better heat stability, dimensional accuracy, and chemical resistance. The long fiber reinforcement significantly enhances mechanical strength, impact resistance, dimensional flatness, and fatigue performance. It is ideal for structural and metal replacement parts used in extreme environments.
