    Characteristics of PBI Compounds

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. PBI has never used Perfluroroalkyl Substances or Polyfluoroalkyl Substances.

 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.
