Kimya PEKK-SC is a high-performance 3D printing filament made from polyetherketoneketone (PEKK), a semi-crystalline thermoplastic in the polyaryletherketone family. The semi-crystalline structure of PEKK-SC provides enhanced heat resistance, making it ideal for use in extreme environments. It combines excellent mechanical strength with resistance to abrasion and harsh chemicals, including acids, fuels, and lubricants. PEKK-SC is also compatible with smoke and fire safety standards, making it suitable for critical applications in aerospace, automotive, and industrial sectors.
• Flame retardant.
• Aerospace Standard.
• Excellent Temperature and Chemical Resistance.
