The TECAFIL PES filament, based on the high performance plastic polyethersulfone, is characterised above all by its excellent physical properties. In addition to its transparent, slightly amber colour, which results in good light transmission, PES (sometimes also referred to as PESU) is also heat resistant, creep resistant and particularly dimensionally stable.
TECAFIL PES filament offers exceptional temperature resistance, making it particularly suitable for applications requiring tight tolerances and minimal dimensional changes over a wide temperature range. The high temperature resistance of TECAFIL PES filament allows it to withstand extreme heat and cold without compromising its structural integrity. This characteristic makes TECAFIL PES filament ideal for applications in engineering, aerospace, automotive and other industries where precision and reliability are paramount.
In addition, the low dimensional variability of the filament allows parts to be manufactured with high precision and consistent quality over a wide temperature range. This is particularly important in applications where any dimensional variation can be critical, such as machine components.
