PBI PEEK Compounds

Quality Characteristics

Polybenzimidazole (PBI) is one of the highest performing engineering thermoplastic materials. It is a fully aromatic heterocyclic thermoplastic polymer that provides the ultimate in thermal mechanical properties and sets the standard for engineering polymer performance. This material is characterized by a glass transition temperature of 427 °C and a broad chemical resistance. PBI is the best polymer for mechanical usage: parts can work harder and last longer. The modified grades are mechanically tough and have very good friction and wear properties.

Combining the superior mechanical properties and thermal resistance of PBI with the melt process ability of polyaryletherketones (PEEK or PEKK), these products offer cost-effective high performance.

The advantage of Celazole® T-Series over ordinary PEEK is the unexpected property set that results from the combination with PBI and other fillers (when present) that yield higher heat deflection temperatures (HDT), higher moduli, higher strength, improved wear resistance and lower creep. In the T-Series composites, HDT’s can be raised to 320ºC, just below the crystalline melting point of PEEK.

  • Highest performing engineering thermoplastic
  • Glass transition temperature of 427 °C
  • Chemical resistance
  • Work harder and last longer
  • Excellent friction
  • Wear properties even at high PV-limits

Applications

As PBI has minimal outgassing properties, it is very attractive to semiconductor manufacturers.

Celazole® T-Series products are PBI compounds designed for injection molding and extrusion.

A desirable balance of performance and tractability is obtained with the T-Series products that place the group’s thermo-mechanical performance above PEEK, but below PBI. T-Series is designed for injection molding of parts that perform, but are cost effectively produced.

These PBI compounds are suitable for various insulation applications, electrical parts and aerospace and automotive.

  •                Sealings, bearings, glide-rings
  •                 Semiconductor industries
  •                 Aviation and space-flight applications
