1,4-Bis(3,4-dicarboxyphenoxy)benzene dianhydride (HQDPA for short) is an organic compound. HQDPA is a pale yellow to white crystal with a strong, irritating odor. It is insoluble in water but soluble in most organic solvents such as alcohols, ethers and ketones. HQDPA decomposes at high temperatures and emits toxic gases.
1,4-Bis(3,4-dicarboxyphenoxy)benzene dianhydride is mainly used as a raw material for polyimide resins and is widely used in electronics, medical, aerospace and automotive industries.
It has excellent high temperature resistance, corrosion resistance and electrical insulation properties, and can also be used in the manufacture of electronic components, sensors, insulating coatings and so on.
