名古屋化学工業所 List of Products and Services

"Meireji Coat" is a polyamic acid solution, which is a precursor to polyimide (high-performance engineering plastic). By performing solvent removal and imidization reactions, it is possible to obtain a polyimide coating with excellent heat resistance, chemical resistance, and electrical insulation properties. It can be diluted with NMP or DMAc (N,N-Dimethylacetamide), or adjusted in temperature to be used at the desired solution viscosity. 【Features】 ■ We offer varnish grades optimized for each application and characteristic to meet customer requirements. ■ Viscosity and concentration can be customized to match customer usage conditions. *For more details, please download the PDF or feel free to contact us.

"Meireji Coat" is a polyimide precursor made from BPDA (3,3',4,4'-biphenyltetracarboxylic dianhydride). The coatings produced from the polyimide precursor exhibit excellent performance. Polyimide coatings show high thermal decomposition temperatures and do not soften, flow, or decompose at the usage temperature, making them suitable for high-temperature processes. 【Features】 ■ A range of varnish grades optimized for different applications and characteristics to meet customer needs. ■ Viscosity and concentration can be customized to match customer usage conditions. *For more details, please download the PDF or feel free to contact us.

Our company offers contract manufacturing of polyimide resin compatible with kilo lab operations. To avoid the "valley of death" between research and mass production, we propose manufacturing solutions that can accommodate products in the expansion stage through "kilo lab" designs ranging from approximately 20kg to 3000kg. We support special heat-resistant resins from research to mass production. Please feel free to contact us when you need assistance. 【Recent Development Products】 ■Special heat-resistant resins (polyimide-based, filler-added resins) *For more details, please download the PDF or feel free to contact us.

"Soluble polyimide" is a polyimide solution or polyimide powder that can be molded at low temperatures compared to conventional polyimide precursor varnishes. Molding is possible at 100 to 200°C depending on the choice of solvent. It completely dissolves (DMAc immersion test). Please feel free to contact us when you need our services. 【Features】 ■ Soluble: Soluble in common solvents (DMAc, NMP, etc.) ■ Low-temperature molding: Molding is possible at 100 to 200°C depending on the choice of solvent ■ No imidization required: Can be used without conventional imidization treatment (300 to 400°C) *For more details, please download the PDF or feel free to contact us.

We would like to introduce our "Transparent Polyimide." This product can be molded with heat treatment below 250°C. Additionally, the resulting film demonstrates high insulation properties. Please feel free to contact us when you need assistance. 【Features】 ■ Insulation: The resulting film shows high insulation properties. ■ Transparency: Achieves high transmittance over a wide wavelength range. ■ Low-temperature molding: Can be molded with heat treatment below 250°C. *For more details, please download the PDF or feel free to contact us.

"Porous Polyimide" is a porous-forming varnish primarily based on PMDA-ODA. It can be produced at the same heat treatment temperature as conventional polyimides. The resulting film exhibits a low dielectric constant, and the porosity can be adjusted as desired. Please feel free to contact us when you need our services. 【Features】 ■ Low Dielectric Constant: The resulting film shows a low dielectric constant (can be adjusted arbitrarily from 2.0 to 2.9). ■ Control of Porosity: The porosity can be adjusted as desired (porosity from 1% to 70%). *For more details, please download the PDF or feel free to contact us.
