Technology & Products
Key Products
POTICON Filament grades NTL34M, NTL34MB, NTL36 and RT4 (RT4 has a 231.9 °C heat deflection temperature at 1.80 MPa); POTICON injection-molding compounds; TISMO potassium titanate fibers; WHISTATT conductive compounds.
Technical position · AMPulse analysis
Proprietary TISMO ultra-fine potassium titanate fibers (about 10-20 µm long, 0.3-0.5 µm diameter), which give low nozzle aggressiveness, good sliding properties and high heat resistance.
Differentiation
Value Proposition
Fiber-reinforced engineering filaments based on ultra-fine TISMO potassium titanate fibers, giving high strength, dimensional accuracy and sliding properties with low nozzle wear on standard hardware.
How They Differentiate
Fine potassium titanate fiber reinforcement works on standard 0.4 mm nozzles without hardened components, and the filament is validated on a specific printer (Gutenberg G-ZERO), unlike generic carbon- or glass-fiber filaments.
