Diamine compound

Diamine compound

"Dimian compounds" applied as raw materials for new materials.

"Diamine compounds" are products developed for use in resins such as polyimides, polyamides, and polyurethanes, as well as for epoxy resin curing agents. They have a rigid molecular structure and exhibit high solubility in organic solvents. They can be applied as raw materials for new materials with excellent properties such as high heat resistance, low thermal expansion, and low water absorption. [Features] - Achieves a soluble polyimide that is rigid - Achieves a polyimide with good dimensional stability and a melting point *For more details, please download the PDF or feel free to contact us.

Ester-type diamine compound "PHBAAB"

Ester-type diamine compound "PHBAAB"

Highly effective for applications requiring high-frequency characteristics! It also demonstrates excellent environmental stability.

"PHBAAB" is a compound developed with the aim of improving heat resistance, low thermal expansion, and low dielectric properties. It achieves a high Tg due to its rigid aromatic framework while suppressing the formation of intermolecular CTC (charge transfer complexes) through the steric hindrance effect of the phenyl groups. The ester bonds and the hydrophobicity of the phenyl groups are expected to result in low water absorption. Additionally, by partially disrupting the planarity of the molecule through aromatic ester bonds and phenyl substitution, it suppresses the coloring of polyimide and improves visible light transmittance. It is suitable for transparent polyimide and display applications. [Features] ■ Achieves high Tg due to a rigid aromatic framework ■ Suppresses the formation of intermolecular CTC through the steric hindrance effect of phenyl groups ■ Expected low water absorption due to ester bonds and the hydrophobicity of phenyl groups ■ Suppresses the coloring of polyimide and improves visible light transmittance *For more details, please download the PDF or feel free to contact us.

Ester-type diamine compound "TBBAAB"

Ester-type diamine compound "TBBAAB"

Achieving low dielectric constant through CTC suppression design makes it suitable for high-frequency applications!

"TBBAAB" is an ester-type diamine compound with a tert-butyl (t-Bu) group introduced in the second position. It features an aromatic skeleton with an ester bond in the center and amino groups at both ends, providing a structure suitable for polyimide polymerization. The rigid aromatic skeleton maintains a high glass transition temperature while improving thermoplasticity and processability. The t-Bu group introduces significant steric hindrance, suppressing the formation of intermolecular charge transfer complexes (CTC) and contributing to improved visible light transmittance. The combination of hydrophobicity and ester bonds also achieves low water absorption. **Features** - Maintains a high glass transition temperature while improving thermoplasticity and processability - Suppresses the formation of intermolecular CTC, reducing the coloring of polyimides - Achieves low water absorption through the combination of the hydrophobic t-Bu group and ester bonds - Facilitates the achievement of low dielectric constant through CTC suppression design *For more details, please download the PDF or feel free to contact us.*
