General Description NTR-874 is a chrome(Cr) based catalyst used in UNIPOL process to  produce LLDPE products with medium molecular weight distribution (MFR=50-90). In term of operating conditions and performance in the reactor, NTR-874 is similar to traditional F-4 catalyst, however, due to the improvement in the support and electron donor, its properties are somewhat improved. Therefore, NTR-874 is supposed to be an excellent substitute of F-4 catalyst.   Specification Cr content: 0.18-0.22 wt% Ti content: 3.0-4.0 wt% Cr(Ⅵ) content 0.15-0.22 wt% Catalyst Bulk Density 240-270 kg/m3 Catalyst Productivity 6000-10000 kgPE/kgCat
