eSUN ePEEK-PRO 1,75mm naturel 0,25kg filament

Introducing the eSUN ePEEK-PRO filament, a high-performance polyether ether ketone (PEEK) material engineered for demanding industrial applications. This 1.75mm diameter filament in natural color offers exceptional thermal and mechanical properties, making it ideal for aerospace, medical, automotive, and other high-performance parts. With a net weight of 0.25kg, it is perfect for prototyping and small-scale production.

Advantages

ePEEK-PRO provides outstanding chemical and wear resistance, high tensile strength, and excellent thermal stability. It maintains its integrity at elevated temperatures, with a heat deflection temperature of 150°C and a glass transition temperature of 143°C. The filament's tight diameter tolerance of ±0.03mm ensures consistent extrusion and reliable print quality.
