Borealis Nucleation Technology (BNT)
BNT is a state-of-the-art in-situ nucleation technology that distinguishes BF970MO from conventionally nucleated polypropylenes. Unlike traditional post-reactor compounding methods, BNT introduces nucleation sites directly during polymerization in the Borstar® reactor process.
This results in a more uniform distribution of nucleation sites, leading to faster crystallization kinetics, enhanced processing efficiency, and superior mechanical properties while maintaining excellent part quality and purity.

Mechanical Properties Overview
Impact Strength vs Temperature
Injection Molding & Processing Guidelines
Processing Advantages
- Designed for high-speed injection molding
- Easy to process on standard equipment
- Wide processing temperature window
- Low mold temperature requirements
- Fast injection speeds possible
Economic Benefits
- 10-20% cycle time reduction
- Reduced energy consumption
- Up to 10% downgauging potential
- Increased production throughput
- Lower manufacturing cost per unit
| Parameter | Typical Value/Range | Rationale & Expert Notes |
|---|---|---|
| Melt Temperature | 210-260°C | Wide processing window provides operational flexibility. Lower end minimizes energy consumption, higher end ensures complete filling of thin-walled parts. |
| Mould Temperature | 10-30°C | Notably low range enabled by BNT accelerated crystallization. Key advantage for shorter cooling times and reduced cycle times. |
| Injection Speed | As high as possible | Good flowability (MFR 20) permits fast injection speeds, minimizing mold fill time and preventing short shots. |
| Holding Pressure | 200-500 bar | Optimize for specific part geometry. Apply minimum pressure to compensate for shrinkage and prevent sink marks. |
