Ester-type dianhydride "TADBHQ" for low dielectric polyimide
Ideal for fields requiring high-frequency characteristics! It significantly contributes to the high performance of communication and advanced devices.
"TADBHQ" is a novel ester-type anhydride that suppresses interchain CTC due to its aromatic ester structure positioned at the center of the main chain, achieving high transparency and low coloration. By introducing tert-butyl (t-Bu) substitution, it improves the solubility and processability of polyimide resins (compatible with high varnish concentrations). While it slightly lowers the Tg (glass transition temperature), it allows for improvements in thermoplasticity and ductility. Additionally, it is easy to achieve low water absorption and low dielectric constant, and it excels in low CTE (low thermal expansion) design as well as adhesion and composite suitability. 【Features】 ■ Suppresses interchain CTC, achieving high transparency and low coloration ■ Improves the solubility and processability of polyimide resins (compatible with high varnish concentrations) ■ Allows for improvements in thermoplasticity and ductility ■ Easy to achieve low water absorption and low dielectric constant ■ Excels in low CTE design and adhesion/composite suitability *For more details, please download the PDF or feel free to contact us.
