Special engineering plastics have demonstrated unparalleledadvantages in many fields due to their excellent comprehensive performance, however, polybenzimidazole(PBl)is the leader above all special engineering plastics.

l Ultra high-temperature resistant: 760 'C instantaneous temperature tolerance, over 300 'C long-term working temperature and over 400'C glass transition temperature.
l Strong acid and alkali resistance and chemical stability: PBl can maintain stable performance in extremely corrosive working environments with strong acid and alkali.
l Mechanical properties: The highest compressive strength, excellent tensile strength and bending strength.

Repazole™,with its excellent performance, can adapt to applications which are ultra high-temperature, strong chemical corrosiveness and extremely high durability requirements that other materials can not meet, such as in aerospace where high mechanical strength and instantaneous temperature tolerance are required, in flame-retardant fibers like firefighter uniforms with high working environment temperatures. Meanwhile, the application scenarios have been greatly expanded because of the designability of Repazole™'s molecular structure. By compounding with other polymers, Repazole™ can also be applied to proton exchange membranes in the hydrogen energy, oxidation-etched,  semiconductor components, corrosion-resistant, marine engineering components, and so on.
