The Kimya PEKK Carbon 3D filament belongs to the polyaryletherketone family. Polyetherketoneketone (PEKK) is a thermoplastic polymer reinforced with carbon fibre. This combination gives it a high level of rigidity and heat-resistance. It can be used as a material in components exposed to acids and hydrocarbons, such as fuel and lubricants, and also to produce components located in engine housings. The Kimya PEKK Carbon 3D filament has the following properties:
- Temperature resistance
- Reinforced with carbon fibre
- Complies with the REACH standard
2-year ARMOR warranty.
(PEKK) is a material derived from semi-cristalline thermoplastics, the polyaryletherketones (PAEKs). It is a family of materials that offers excellent thermomechanical properties and also includes PEEK, the material from the family currently most widely used.
PAEK is composed of ether and ketone; their ratio and functions influence the polymers’ glass transition and fusion temperature, thereby affecting their thermal resistance and blocking temperature. It is a material that offers numerous advantages such as its high level of rigidity; it is frequently compared to aluminium, although it is 40% lighter. It also offers a high level of resistance to UV and high temperatures, in addition to good chemical and abrasion resistance. However, it is expensive and difficult to transform. Additionally, few 3D printers are able to use the filament, further restricting its possibilities. Its rough surface and limited colours (black, blue, beige and green) are also drawbacks for PAEK.
