The INTAMSYS PEEK-GF Filament is a high-performance 3D printing filament designed for professional and industrial applications. Engineered with polyetheretherketone (PEEK) reinforced with glass fibers (GF), it offers exceptional strength, heat resistance, and mechanical performance. This filament is ideal for creating robust, heat-resistant parts that can withstand high mechanical stress, making it suitable for industries such as aerospace, automotive, and manufacturing. With its outstanding dimensional stability, chemical resistance, and compatibility with INTAMSYS industrial-grade 3D printers, the INTAMSYS PEEK-GF filament unlocks new possibilities for creating durable and reliable objects in challenging environments.

The INTAMSYS PEEK-GF filament stands out with its exceptional tensile strength, rigidity, and heat resistance. With a glass transition temperature (Tg) of approximately 150°C and a melting temperature (Tm) exceeding 300°C, it can withstand extreme temperature environments without compromising its structural integrity. Its chemical resistance to various substances further extends its applicability in industries requiring resistance to harsh chemicals. Experience the power of INTAMSYS PEEK-GF and unleash the potential of reinforced PEEK for your most demanding 3D printing projects.
