GAZOLE™ Polybenzimidazole (PBI) – Exceptional Performance for Extreme Environments

At JesMetal Chemie, we proudly offer GAZOLE™ Polybenzimidazole (PBI), a high-performance semi-crystalline polymer renowned for its unparalleled thermal stability, chemical resistance, and inherent flame retardancy. With a glass transition temperature of 427°C, PBI stands as one of the most heat-resistant engineering thermoplastics available, making it ideal for applications subjected to extreme conditions.

Key Features

Outstanding Thermal Stability: PBI maintains its mechanical properties at continuous operating temperatures up to 540°C and does not exhibit a melting point, ensuring structural integrity in high-temperature environments.
Exceptional Chemical Resistance: Resistant to a wide range of chemicals, including hydrocarbons, acids, and solvents, PBI is suitable for use in harsh chemical environments where other polymers may degrade.
Inherent Flame Retardancy: With a Limiting Oxygen Index (LOI) of 58%, PBI does not ignite or sustain combustion in air, making it inherently flame-resistant without the need for additional flame retardant additives.
High Mechanical Strength: PBI exhibits superior tensile and compressive strength, low creep, and excellent wear resistance, ensuring durability and longevity in demanding applications.
Dimensional Stability: The polymer maintains its shape and size under mechanical stress and thermal cycling, providing reliable performance in precision components.
Low Outgassing and High Purity: PBI’s low outgassing properties make it suitable for vacuum environments and applications requiring high material purity, such as semiconductor manufacturing.
