Technology

Borstar^® Polypropylene (PP) is Borealis’ proprietary Low-Pressure, Catalytic Technology for Manufacturing a full package of Polypropylene Materials.

The whole Process can be divided in the following Areas:

• Feedstock Preparation;
• Reactor Area;
• Recovery Area;
• Dry End (comprising pelletizing);
• Material Handling, comprising Bagging and Storage Area.

The reactor part of the Borstar^® Polypropylene Modular Technology consists of a Series of Slurry-Loop and Gas-Phase Fluidized Bed Reactors (GPR), where each Reactor can be independently controlled. Typically, an additional Pre-Polymerization Loop Reactor precedes the Reactor Cascade. Homopolymers, Random Copolymers as well as Heterophasic Matrix Copolymers can be produced by employing this Technology that enables tailoring the Molecular Weight Distribution (MWD), Isotacticity and Comonomer Content (CC) along the MWD.
