SEMITI 2160 vs Kronos 2160

SEMITI 2160 matches Kronos 2160's outdoor PVC durability for window frames, siding, and fence boards.

Kronos 2160 is the European reference for outdoor PVC applications — heavy alumina + zirconia surface treatment specifically tuned to minimize photodegradation of PVC. SEMITI 2160 is the direct alternative.

Common questions

Can SEMITI 2160 substitute Kronos 2160 in outdoor PVC window frame extrusion?+
Yes — both share heavy Al₂O₃ + ZrO₂ surface treatment tuned for outdoor PVC. Test on your extrusion line: thermal stability + 5-year accelerated weathering. PVC stabilizer compatibility (Ca/Zn systems) is the key qualification gate. Typical qualification cycle: 4–8 weeks.
How much cheaper is SEMITI 2160 vs Kronos 2160?+
Kronos 2160 lands in Asia at USD 3.80–4.20/kg; SEMITI 2160 at USD 2.50–2.90/kg — a 30–40% cost advantage. For PVC profile extruders in Asia or Eastern Europe running high annual volumes, this savings is significant.
When should I keep using Kronos 2160 rather than switching?+
Keep Kronos 2160 when EU window frame fabricators with established Kronos qualifications are your primary customer base and requalification would disrupt supply. For new production lines or Asia-Pacific operations without existing Kronos qualification, SEMITI 2160 is the cost-optimal starting point.
