The Kimya PEKK-SC 3D filament belongs to the polyaryletherketone family. Polyetherketoneketone (PEKK) is a semi-crystalline thermoplastic polymer. PEKK-SC is PEKK in semi-crystalline form, imparting it with increased heat resistance. It is therefore resistant to high temperatures, abrasion and chemical products. Manufactured from KEPSTAN® Arkema, PEKK has excellent mechanical properties. Manufacturers use it to produce components exposed to acids and hydrocarbons, such as fuel and lubricants. It is compatible with the smoke/fire standard EN 45 545 – essential in the railway sector. The Kimya PEKK-SC 3D filament has the following properties:

• Semi-crystalline structure


• Excellent mechanical properties


• Heat resistance (up to 260°C)


• Railway fire and smoke standard EN45545


• Aerospace FAR 25.853 Standard


• Flame retardant – eligible to UL94 V0


• Complies with the RoHS and REACH standard
