Rutile titanium dioxide DR-2589
Product classification:
DR-2589 is a specially designed plastic Rutile grade with good durability. DR-2589 specialties are super bluish undertone, outstanding lightness in coloring and excellent opacity. The special inorganic treatment of dense amorphous silica and alumina protect the surface of TiO2 from acting with polymers or additives. The organic surface treatment ensures DR-2589 outstanding dispersion, processibility and low hygroscopicity in plastics production. The new treatment technology of DR-2589 can effectively improve the heat resistance, light fastness and weathering of plastics and keep them free from UV lights. So DR-2589 is enabling to improve the plastics mechanical property and also the insulation when used in cable.

Note:
1. It is tested in white PVC-P system containing plasticizer with titanium dioxide content of 4PHR.
2. It is tested in grey PVC-P system containing plasticizer and carbon black with titanium dioxide content of 4PHR.
3. It is tested in linear low density polyethylene (MFR: 25g/10min) masterbatch with titanium dioxide content of 70%.
4. Linear low density polyethylene masterbatch with titanium dioxide content of 70% is diluted with low density polyethylene (LDPE) as the base resin and tested according to ISO23900-5:2015.
5. After the test of volatiles at 105℃, titanium dioxide is put into an oven with a constant temperature of 300℃ and heated for 2h to calculate the heating loss.
