“Why is others’ plastic film so bright white while their costs are lower than yours?” In the field of industrial manufacturing, the selection of titanium dioxide directly determines the product’s appearance and cost structure. Choosing the wrong one may quietly increase the cost by thousands of yuan per ton!

The domestic product recommended to you next — 930 Rutile Titanium Dioxide, with the posture of a “cost-effective all-rounder”, has become a “money-saving tool” for more and more manufacturers!

01  Purity and performance outperform competitors

🔹The core value of titanium dioxide first depends on its purity. 930 adopts imported sand mill wet grinding process to achieve remarkable particle size uniformity, eliminating color difference and spots caused by coarse particles from the source.
🔹More importantly, its crystal form purity — rutile content is as high as 98%, combined with more than 94% TiO₂ content, endows the product with ultimate whiteness (L value 95.0) and scattering power (100%).
🔹This indicator is directly reflected in the finished products: for plastic films of the same thickness, the covering power is increased by about 20%, which means that the same effect can be achieved with less dosage.

 

02  Easy to disperse, saving time and energy consumption

What troubles engineers most about traditional titanium dioxide is agglomeration and difficulty in dispersion, which not only prolongs working hours but also increases equipment wear! 930 breaks through through two innovations:
🔹On the one hand, it adopts silica/alumina dense coating technology to reduce particle surface energy;
🔹On the other hand, the oil absorption is controlled at a low level of 21g/100g, combined with the excellent performance of Hegman dispersion index 5.5.
🔹Verified in actual production: in PE masterbatch processing, the dispersion time is shortened by 15% and energy consumption is reduced by about 8%. A production manager of plastic pipes sighed: “It used to take 40 minutes to grind the material, but now it becomes uniform in 34 minutes!”

 

03  Adaptability to break through scenario limitations

Through flexible organic-inorganic composite treatment process, 930 titanium dioxide can perfectly meet the needs of different systems with the same product:
▶ Paper industry: improve coating whiteness while reducing powder falling rate
▶ Plastic pipes: weather resistance extends outdoor service life by more than 30%
▶ Packaging films: high covering power enables thinning and cost reduction
▶ Color masterbatches: optimized fluidity avoids injection molding color streaks
