Working with TPC (COPE/TPEE) HS-UV
Is TPC (COPE/TPEE) easy to machine?
Soft grades smear and deflect — use very sharp positive-rake tools, high speed/low feed, chilled or fixtured workpieces; hard 72–82 D grades machine much like acetal.
Can TPC (COPE/TPEE) be welded?
Readily joined by hot-plate, ultrasonic, vibration, HF/RF and laser welding; solvent bonding is poor, use polyurethane or cyanoacrylate adhesives after plasma/primer treatment.
Can TPC (COPE/TPEE) be formed, bent or molded?
Dry to <0.05 % (2–3 h at 100–110 °C) to prevent hydrolytic MW loss; inject at 200–250 °C melt, 20–60 °C mould, fast fill with generous gates; also extrudable, blow-mouldable and 3D-printable as filament.
What surface finishes work on TPC (COPE/TPEE)?
Takes in-mould texture and pad/screen printing with PU inks after flame or plasma treatment; not electroplatable, and overmoulds well onto PBT, PET and PC/ABS substrates.

TPC (COPE/TPEE) HS-UV is rated for continuous use to about 135°C (275 °F), and briefly to 165°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.

55D is the default condition — default balance of elasticity, strength and heat resistance; the workhorse for boots, couplings, hose covers, gears and seals. 82D: hardest standard TPEE, near-engineering-plastic stiffness with high impact toughness; used for hose reinforcement, ski/boot shells and structural clips.
