SEMITI 960
High thermal stability for engineering plastics — extrusion to 300°C without yellowing.
SEMITI 960 is a chloride-process rutile TiO2 specifically engineered for high-temperature plastic masterbatch — particularly for engineering plastics (ABS, PC, PA6, PA66, PBT) and high-loading masterbatch (60–70% TiO2) in PE and PP carriers. It is the direct counterpart to Chemours Ti-Pure R-960.
The amine-compatible organic surface treatment serves two distinct functions. First, it provides excellent thermal stability up to 300°C — the upper end of engineering plastic compounding temperatures. Second, the amine compatibility means SEMITI 960 will not antagonize HALS (hindered amine light stabilizers) in outdoor-service compounds. This is a major formulation advantage over universal rutile grades whose surface treatments can deactivate HALS over time.
In high-loading masterbatch (60%+ TiO2), the rapid wet-out behavior of SEMITI 960's surface treatment dramatically reduces extruder torque and improves dispersion quality. Customers running 70% loading masterbatch in twin-screw extruders typically see 15–20% lower torque vs universal rutile grades.
Why customers pick SEMITI 960
- 01Thermal stability to 300°C — engineering plastic safe (ABS, PC, PA, PBT)
- 02HALS-compatible amine surface treatment — no antagonism in outdoor-service compounds
- 03High-loading capable — runs cleanly at 60–70% MB loading
- 04Volatiles < 0.30% at 105°C — no splay in injection molded parts
