优质的加工性能

At the same high loading concentration, DW-1070 causes a significantly smaller reduction in the resin's melt flow index (MFI) compared to conventional titanium dioxide of equivalent quality, thereby minimizing the impact on melt flowability. Furthermore, compounding time is shortened, and viscosity drops substantially at high shear rates, which ultimately boosts processing efficiency and finished product uniformity.

Excellent Lacing Resistance

When evaluated at an identical 70% loading across various shear rates, our product demonstrates a significantly smaller variation in viscosity compared to the benchmark titanium dioxide. This means that our product is exceptionally well-suited for high-temperature extrusion coating and lamination applications (such as packaging material production). During these high-speed, high-temperature manufacturing processes, it effectively reduces the risk of pinholes, cracking, or lacing defects on the film surface, thereby safeguarding overall product quality.

Melt viscosity directly controls how a TiO₂-loaded compound behaves during extrusion, coating, and film-blowing. Two samples were tested at identical loading — 30% LDPE (12 MFI) as the carrier resin plus 70% of either (1) DW-1070, Super-dispersed TiO₂ Masterbatch or (2) reference rutile titanium dioxide, TiO₂(616S). At 190 °C, DW-1070 shows a much flatter viscosity profile than the reference — starting at ~6575 Pa·s vs ~20800 Pa·s at low shear, and converging at high shear. This makes DW-1070 especially suited to high-temperature extrusion coating and lamination (e.g., flexible packaging) where high speeds and high temperatures otherwise risk pinholes, cracks, and surface defects in the finished film.

提升混炼效率

加入 DW-1070 可显著缩短物料达到均匀熔融状态所需的时间，从而缩短加工周期、提高生产效率，并降低单位能耗和综合制造成本。

图 2 密炼机功率曲线

Internal mixer power consumption is a direct measure of how much energy is needed to incorporate and disperse a pigment into the resin. Two samples were compared in an internal mixer (Banbury / BR) — 30% LDPE (12 MFI) carrier resin plus 70% of either (1) DW-1070, Super-dispersed TiO₂ Masterbatch or (2) reference rutile titanium dioxide, TiO₂(616S). The reference powder needs full wetting and dispersive mixing — peak power climbs to ~27 kW with fusion at ~41 s. DW-1070, already pre-dispersed in carrier resin, only requires distributive blending — peak power stays around ~13 kW with fusion at ~10 s, then settles to a low, steady ~8 kW.

~52% Lower Peak Power

Pre-dispersed pigment means no need for high-energy dispersive mixing — peak motor load drops dramatically, protecting motor and gearbox from overload trips.

~4× Faster Fusion

Fusion in ~10 s instead of ~41 s shortens cycle time, multiplies batch throughput on the same equipment, and reduces residence time at high temperature.

Lower Energy & Cost per kg

Lower peak + shorter cycle = significantly less kWh per kilogram of compound, with the bonus of less wear on rotors and chamber walls.

Low Volatile Content

This prevents the formation of bubbles and silver streaks (splay marks) during processing, effectively guaranteeing a high finished product yield.

低挥发分对于高温塑料加工至关重要。水分或其他挥发性物质含量过高，容易导致气泡、银纹和制品表面缺陷。 DW-1070 在150℃条件下仍能保持初始质量的99.5%，表明其挥发分极低，能够满足高要求的挤出及注塑加工条件。
