Detailed Introduction

Repazole® PBI Compounds (E Series)

Product Overview

Repazole® PBI compounds are produced by blending and pelletizing PBI with PEEK / PEKK. They combine the excellent heat resistance of PBI with the melt processability of thermoplastics and can be molded into complex parts by injection molding or extrusion. The material retains its properties at 260 °C, keeping more than 70% of its high-temperature performance, offering a scalable, cost-effective solution for high-temperature wear applications.

Key Features

  • High-temperature resistance: glass transition temperature of 310 °C, retaining properties at 260 °C and keeping over 70% of high-temperature performance;
  • Melt-processable: supports injection molding and extrusion for volume production of complex parts;
  • Two matrices: PBI-PEEK and PBI-PEKK blend systems, the latter with higher temperature resistance;
  • Multiple grades: unfilled, carbon/glass-fiber reinforced, and self-lubricating options;
  • Engineered balance: balancing high-temperature performance, process efficiency, and cost.
