PA12-LCF5 | 5% Long Carbon Fiber Reinforced Polyamide 12
PA12-LCF5 is a lightweight, toughened engineering thermoplastic that combines the excellent chemical resistance, low moisture absorption, and flexibility of Polyamide 12 (PA12) with 5% long carbon fiber reinforcement. The addition of long carbon fibers introduces enhanced dimensional stability, tensile performance, and impact resistance—while preserving the ductility and low warpage characteristics of unfilled PA12.
Optimized for applications that require moderate mechanical performance, reduced part weight, and consistent performance in humid or chemically aggressive environments, PA12-LCF5 is ideal for housings, enclosures, and light-duty structural parts across automotive, electronics, consumer products, and industrial devices.
