DR-2588 Rutile Titanium Dioxide
DR-2588 is a rutile titanium dioxide pigment designed specifically for plastic applications, with strong blue background color tone, excellent coloring brightness, and outstanding coverage. Its special surface treatment ensures extremely low moisture absorption, low high-temperature volatile matter, ultra-low oil absorption, and outstanding dispersibility and processing flowability in plastics.

description2
Note: 1. Tested in a polyvinyl chloride system (PVC-P) containing plasticizers with a titanium dioxide content of 4PHR.
2. Tested in a polyvinyl chloride system (PVC-P) containing plasticizers and carbon black with a titanium dioxide content of 2PHR.
3. Detect in linear low-density polyethylene (MFR of 25g/10min) masterbatch with a titanium dioxide content of 70%.
4. Linear low-density polyethylene (LLDPE) masterbatch with 70% titanium dioxide content is made of low-density polyethylene
Dilute LDPE as the base resin and test according to the European standard EN1390-5:2005.
5. After testing for volatile compounds at 105 ℃, the titanium dioxide was placed in a constant temperature oven at 300 ℃ and heated for 2 hours to detect the heating loss.
