stability
The relative density of PBI film is 1.26, the tensile strength is 60.76MPa, low temperature and heat resistance is very good, at -196℃ no brittle, glass temperature 480℃, 550℃ in the air began to decompose, can be used at 270℃ for a long time, PBI adhesive has high temperature bonding strength. It is bonded with steel and has a shear strength of 19.6-21.56MPa at room temperature. The temperature is 16.66-21.56MPa at 200℃ and 16.66-19.6MPa at 300℃. PBI glass cloth laminate has excellent high temperature resistance, and long-term temperature resistance can reach 427℃. The hydrolysis stability of PBI is quite high. The polymer viscosity does not change after 5h in 95% sulfuric acid at 160℃, and the polymer viscosity does not change after 10h in 70% sulfuric acid or 25% potassium hydroxide solution heated reflux. It can be dissolved in concentrated sulfuric acid, dimethylformamide, dimethyl sulfoxide, N-methylpyrrolidone and hexamethylphosphamide.
