Working with Extem XH1015 UNF
Is Extem XH1015 easy to machine?
Machines like a hard amorphous resin — sharp positive-rake carbide, high speed and light feed with air or mist cooling; avoid sharp internal corners and use annealing (≈240 °C, slow cool) after heavy cuts to relieve stress-cracking risk.
Can Extem XH1015 be welded?
Joined by ultrasonic, vibration and laser welding or by adhesive bonding after plasma/abrasion prep; hot-plate welding is difficult because of the very high softening temperature.
Can Extem XH1015 be formed, bent or molded?
Injection mold at 380–420 °C melt with 175–230 °C tool, hot runners rated for the temperature, drying 4–6 h at 150–160 °C to <0.02 % moisture; thermoforming of sheet requires >280 °C surface temperature.
What surface finishes work on Extem XH1015?
Takes paint, vacuum metallization and pad printing well after cleaning; the natural amber transparency polishes to optical quality but the resin yellows under sustained UV unless coated.

Extem XH1015 UNF — frequently asked
What is Extem XH1015 UNF used for?
Extem XH1015 UNF is typically used for surface-mount reflow carriers, aerospace ducting and high-temperature electrical bobbins. In short: highest-heat PEI copolymer; tg near 260 °C; survives reflow soldering.
What is the yield strength of Extem XH1015 UNF?
Extem XH1015 UNF has a typical yield strength of 115 MPa (16.7 ksi) and a tensile strength of 115 MPa (16.7 ksi) — stronger than 99% of polymer grades. Strength varies by condition: see the 4 listed tempers.
Is Extem XH1015 UNF easy to machine?
Reasonably — machinability is rated good (55/100, worse than 64% of polymer grades). Machines like a hard amorphous resin — sharp positive-rake carbide, high speed and light feed with air or mist cooling; avoid sharp internal corners and use annealing (≈240 °C, slow cool) after heavy cuts to relieve stress-cracking risk.
Can Extem XH1015 UNF be welded?
With care — weldability is rated fair (35/100). Joined by ultrasonic, vibration and laser welding or by adhesive bonding after plasma/abrasion prep; hot-plate welding is difficult because of the very high softening temperature.
What surface finishes work on Extem XH1015 UNF?

What is the maximum service temperature of Extem XH1015 UNF?
Extem XH1015 UNF is rated for continuous use to about 230°C (446 °F), and briefly to 300°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between Extem XH1015 UNF and Extem XH1015 PTFE15?
UNF is the default condition — default choice for thin-wall connectors, sockets and lenses needing 260 °C Tg with maximum ductility and dielectric performance. PTFE15: choose for unlubricated sliding contact at 200 °C+ where low friction and low wear rate dominate over strength. Yield strength is 115 MPa in UNF versus 90 MPa in PTFE15.
